手动编译安装lanmp centos6.5 64位

对于新手来说一个很大的问题就是连源码包都在到在哪下载，还有就是软件的依赖关系

如果网卡也不会配置，请翻看我的其他文章

这就是基本所需的源码包了

http://pan.baidu.com/s/1kTxbN5X

然后就是开始

yum -y install gcc gcc-c++ autoconf nss_ldap libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel openldap-clients openldap-servers pcre pcre-devel make wget vim cmake gd gd-devel libevent libevent-devel zip unzip libtool
yum基本的rpm包

 

安装完成之后

关闭selinux和防火墙

service iptables stop

chkconfig iptables off

vi /etc/selinux/config 

把SELINUX=enforcing 修改为disabled

centos7是iptables被firewalld替代了

systemctl stop firewalld

 记得改完之后reboot重启或者直接service iptables restart

源码存放路径：/usr/local/src

yum install lrzsz

cd /usr/local/src

rz

可以多选

这个虚拟机比较方便，如果是真机器上，装完系统之后直接wget到src文件里就行

tar -zxvf 源码包

安装httpd

首先安装apr

tar -zxvf apr-1.5.1.tar.gz

cd  apr-1.5.1

 ./configure --prefix=/usr/local/apr

如果你不知道是不是对的，请直接继续，如果在编译httpd有问题可以删掉文件夹，再次编译，没事

make && make install

cd ..

tar -zxvf apr-util-1.5.4.tar.gz

cd cd apr-util-1.5.4

./configure  --prefix=/usr/local/apr-util --with-apr=/usr/local/apr

make && make install

 tar -zxvf httpd-2.4.10.tar.gz

cd httpd-2.4.10

 

./configure --prefix=/usr/local/apache --sysconfdir=/etc/httpd --enable-so --enable-rewrite --enable-ssl --enable-cgi --enable-cgid --enable-modules=most --enable-most-shared=most --enable-mpms-shared=all --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util
配置文件在 /etc/httpd/httpd.conf 

make && make install

cd /usr/local/apache

 bin/apachectl start

 

AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message

如果出现以下问题

vi /etc/httpd/httpd.conf 

首先把pid文件指到run下面，这个和出现的问题无关

在serveRoot="/usr/local/apche" apache的根目录加上。如果USR目录空间不大，可以吧目录指导HOME目录下

PidFile "/var/run/httpd.pid"

配置而已

找ServerName和ServerAdmin改成

ServerAdmin localhost

ServerName localhost：80

ESC

：wq保存退出

netstat -tnlp

kill 80断就的PID

cd /usr/local/apache

 bin/apachectl start

curl 127.0.0.1

It works!、

在别的机器上输入IP，就OK了

网站根目录/usr/local/apache/htdocs 下面index.html就是主页文件

吧httpd加入开机启动

1、将apachectl文件拷贝到/etc/rc.d/init.d 中，然后在/etc/rc.d/rc5.d/下加入链接即可。

命令如下：

cp /usr/local/apache/bin/apachectl /etc/rc.d/init.d/httpd  //如果有其他的版本的Apache存在，也可以直接覆盖掉

ln -s /etc/rc.d/init.d/httpd /etc/rc.d/rc5.d/S85httpd      //建立链接(85的意义后面介绍)

此时Apache就可以自动启动了。

2、 运行chkconfig --list，发现没有linux服务列表中httpd，通过chkconfig --add httpd来添加,但是提示：httpd服务不支持 chkconfig。需要编辑/etc/rc.d/init.d/httpd,添加以下注释信息：任何位置都可以

# chkconfig: 345 85 15

# description: Activates/Deactivates Apache Web Server

第一行3个数字参数意义分别为：哪些Linux级别需要启动httpd(3,4,5)；启动序号(85)；关闭序号(15)。

保存后执行：chkconfig --add httpd,成功添加。

在rc3.d、rc4.d、rc5.d路径中会出现S85httpd的链接文件，其他运行级别路径中会出现K61httpd的链接文件。

3、运行chkconfig --list httpd

 

 

 

接下来是mysql

 这就有个大问题，大文件的mysql源码包是无法使用rz命令，这里有个小技巧

你平常用的ftp工具 除了登陆ftp之外，还是可以用root用户登陆选择sftp over ssh这个就可以用root用户登陆，大文件就可以上传了，不用安装samba和配置

cp /root/mysql-5.6.21-x86_64.tar.gz  /usr/local/

tar -zxvf mysql-5.6.21-x86_64.tar.gz


创建软链接

 

创建用户组合用户id

 groupadd -r -g 306 mysql
 useradd -g 306 -r -u 306 mysql

 id mysql

chown -R mysql.mysql /usr/local/mysql/*

更改属组

mkdir -p /data/mysql
chown -R mysql:mysql /data/mysql
mkdir -p /usr/local/mysql
tar zxvf mysql-5.5.28.tar.gz
cd mysql-5.5.28

cmake
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql
-DMYSQL_DATADIR=/data/mysql/data
-DSYSCONFDIR=/etc
-DWITH_MYISAM_STORAGE_ENGINE=1
-DWITH_INNOBASE_STORAGE_ENGINE=1
-DWITH_MEMORY_STORAGE_ENGINE=1
-DWITH_READLINE=1
-DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock
-DMYSQL_TCP_PORT=3306
-DENABLED_LOCAL_INFILE=1
-DWITH_PARTITION_STORAGE_ENGINE=1
-DEXTRA_CHARSETS=all
-DDEFAULT_CHARSET=utf8
-DDEFAULT_COLLATION=utf8_general_ci

根据自己需求编译选项


make
make install
cd /usr/local/mysql
cp ./support-files/my-medium.cnf /etc/my.cnf

scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/data/mysql/data --user=mysql

chown -R mysql.mysql /data/mysql/data

cp ./support-files/mysql.server /etc/rc.d/init.d/mysqld
chmod 755 /etc/init.d/mysqld
chkconfig --add mysqld
chkconfig mysqld on
chkconfig --list mysqld

vi /etc/rc.d/init.d/mysqld

basedir=/usr/local/mysql/
datadir=/data/mysql/data/
加上
echo 'export PATH=$PATH:/usr/local/mysql/bin' >> /etc/profile  吧mysql的命令加入

source /etc/profile 启动命令

ln -s /usr/local/mysql/lib/mysql /usr/local/lib64/mysql
ln -s /usr/local/mysql/include/mysql /usr/local/include/mysql


service mysqld start

mysql -uroot  登陆 默认密码为空
mysql> SET PASSWORD = PASSWORD('123456'); 设置root密码
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'172.16.%' IDENTIFIED BY 'password' WITH GRANT OPTION;
开始远程访问



初始化的时候请注意
scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/data/mysql/data --user=mysql

这个地方一定要把这2个基本的地址，如果你需要更多的初始化选项参考下面的选项

不然启动服务的时候会出现
mysql The server quit without updating PID file
你启动mysql的时候就会出现这个问题，网上的解决办法很多，但是需要更具你自己的指定的data目录下的错误信息来判断
比如你上面你没指定
--basedir=/usr/local/mysql这个选项
localhost.localdomain.err 这个里面会提示 
Fatal error: Can't open and lock privilege tables: Table 'mysql.host' doesn't exist
因为默认的权限表不在/usr/local/mysql里面

还有一个问题就是/etc/my.ini也是配置文件确保整个的mysqld段里面 

basedir=/usr/local/mysql/
datadir=/data/mysql/data
这2个是和/usr/local/mysql/my.ini里面都是一样
下面是错误日志的路径，如果以上问题还是解决不了。请查看日志

log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

请参考下面的



这里注意下，很多文章没指出的，你下载mysql的源码包是由2中，一种是解压，直接
scripts/mysql_install_db的那个包，有200M左右，现在5.6的差不多有400M。一般你没看到cmake的编译的话，那就这种包
如果你的源码包只有20M-30M，你的包就需要cmake编译，你先的yum install cmake
这里演示的是cmake的




接下来是php


先解决几个编译php的编译选项的依赖库
libmcrypt
mhash
mcrypt
libiconv
上面的源码包都有


cd /usr/local/src
tar zxvf libmcrypt-2.5.8.tar.gz
cd libmcrypt-2.5.8
./configure
make && make install
/sbin/ldconfig
cd libltdl

./configure --enable-ltdl-install
make && make install
cd ../../
tar zxvf mhash-0.9.9.9.tar.gz
cd mhash-0.9.9.9/
./configure
make && make install
ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la
ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so
ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4
ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8
ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a
ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la
ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so
ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2
ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1
ln -s /usr/local/bin/libmcrypt-config /usr/bin/libmcrypt-config
cd ../
tar zxvf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8/
/sbin/ldconfig
./configure
make && make install
cd ../
tar zxvf pcre-8.31.tar.gz
cd pcre-8.31
./configure –-prefix=/usr/local/pcre
make
make install
cd ../
tar zxvf libiconv-1.13.1.tar.gz
cd libiconv-1.13.1/
./configure –-prefix=/usr/local/libiconv

这个地方做好指定，因为编译php的时候会搜索不到这个包


make && make install
cd ../
tar zxvf ImageMagick.tar.gz
cd ImageMagick-6.5.1-2/
./configure
make && make install
cd ../

接下来是重点，因为根据你架构的需求一下有很多不同，比如lamp就使用默认的工作模式即可，如果是lnmp的话就要使用fastcgi
lanmp的也是要使用fastcgi模式
解释下为什么要使用lanmp处理php交给apache处理，静态文件交给nginx处理，因为nginx处理资源文件盒并发的能力更强，nginx作为反向代理有很多好处
比如集群轮换配置简单，并发能力强，目前并发最好的不是nginx而是lvs，但是就整体而言nginx好用程度和能力不逊色与LVS，如果你真的需要大并发的，其实lanmp的搭建方式
不行，以后再详细讨论
./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache/bin/apxs --with-mysql=/usr/local/mysql/ --with-ttf --with-xmlrpc --with-openssl --with-zlib --with-freetype-dir --with-gd --with-jpeg-dir --with-png-dir --with-iconv=/usr/local/libiconv --enable-short-tags --enable-sockets --enable-zend-multibyte --enable-soap --enable-mbstring --enable-static --enable-gd-native-ttf --with-curl --with-mcrypt

这个是默认工作模式，lanmp建议使用这个


./configure --prefix=/usr/local/php --with-mysql=/usr/local/mysql --with-openssl --with-mysqli=/usr/local/mysql/bin/mysql_config --enable-mbstring --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --enable-sockets --with-apxs2=/usr/local/apache/bin/apxs --with-mcrypt --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-bz2 --enable-maintainer-zts --with-curl --enable-fpm --enable-soap --with-iconv=/usr/local/libiconv  --with-mysqli=/usr/local/mysql/bin/mysql_config  --with-freetype-dir=/usr/local/freetype  --with-gd

如果不会安装gd或者libiconv请参看俺的其他文章


这是fpm模式 搭建lanmp必备


vi /etc/httpd/httpd.conf


增加2个东西就可以使用了
   AddType application/x-httpd-php .php .php3 .htm .phtml .php4

   AddType application/x-httpd-php-source .phps

 

支持php文件的支持

在增加支持DirectoryIndex index.php index.html

这个是全局的配置支持默认打开index.php

保存，重启apache

service httpd stop

service httpd start

 

测试

vi /usr/local/apache/htdocs/index.php

<?php

$con = mysql_connect('localhost','root','');

 

if($con){

echo "OK":

}else{

echo "fuck";

}

phpinfo();

?> 

 显示了OK和phpinfo的信息

OK，php和mysql开启了

 

php是作为apache的模块执行，不需要作为服务启动

以下是配置虚拟机

 

 

vi /etc/httpd/httpd.conf
注释掉
# DocumentRoot "/usr/local/apache/htdocs/"
 开启虚拟机主机

include "/etc/httpd/extra/httpd-vhost.conf"

OK

vi /etc/httpd/extra/httpd-vhosts.conf

默认是开启 mod_log_config模块，不放心就自己去

vi /etc/httpd/httpd.conf检查下

配置虚拟主机有2个默认配置

mkdir /www/{a.com,b.com} -pv
mkdir /var/log/httpd/

<VirtualHost *:80>
ServerName www.a.com
DocumentRoot "/www/a.com"
ErrorLog "/var/log/httpd/a.com-error_log"
CustomLog "/var/log/httpd/a.com-access_log" common
</VirtualHost>

<VirtualHost *:80>
ServerName www.b.com
DocumentRoot "/www/b.com"
ErrorLog "/var/log/httpd/b.com-error_log"
CustomLog "/var/log/httpd/b.com-access_log" common
</VirtualHost>

combined的日志文件更丰富

在自己的本地的hosts文件映射

192.168.0.206 www.a.com

192.168.0.206 www.b.com

 

service httpd stop

service httpd start

打开你会发现You don't have permission to access / on this server

因为从httpd2.4起，每个虚拟主机都需要主动配置目录才能访问

 
vi /etc/httpd/extra/httpd-vhosts.conf

<VirtualHost *:80>
ServerName www.a.com
DocumentRoot "/www/a.com"
<Directory "/www/b.com">
Options none
AllowOverride none
Require all granted
</Directory>
ErrorLog "/var/log/httpd/a.com-error_log"
CustomLog "/var/log/httpd/a.com-access_log" common
</VirtualHost>

<VirtualHost *:80>
ServerName www.b.com
DocumentRoot "/www/b.com"
<Directory "/www/b.com">
Options none
AllowOverride none
Require all granted
</Directory>
ErrorLog "/var/log/httpd/b.com-error_log"
CustomLog "/var/log/httpd/b.com-access_log" common
</VirtualHost>

 

 

service httpd stop

serveice httpd start

OK.了

安装phpmyadmin

cd /etc/local/src/

tar -zxvf phpMyAdmin-4.2.11-all-languages.tar.gz -C /www/a.com

就可以了，如果提示空密码不能登陆

mysqladmin -uroot password 'com'

如果提示要使用mysqli，就去再次编译一下php。或者扩展其他模块

 

 

下面是nginx
groupadd nginx
useradd -r -g nginx nginx -s /sbin/nologin
id nginx

tar -zxvf nginx-1.6.2
cd nginx-1.6.2
./configure

这个是php的fpm工作模式的配置

lnmp配置


cd /usr/local/src/php-5.6/
cp php.ini-production /usr/local/php/etc/php.ini
cp php.ini-production /etc/php.ini
这个是默认php.ini的路径

cp sapi/fpm/init.d.php-fpm  /etc/rc.d/init.d/php-fpm

 

cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf 

 vi /usr/local/php/etc/php-fpm.conf
       启用如下选项：
       pm.max_children = 50
       pm.start_servers = 5
       pm.min_spare_servers = 2
       pm.max_spare_servers = 8
       pid = run/php-fpm.pid
根据服务器配置修改

只需要把蓝色部分前面的注释去掉，修改完成，试着启动

/usr/local/php/sbin/php-fpm   

启动后用netstat -tnlp 查看 如果有如图所示端口 测表示正常启动

如需要开机自动启动 则可以添加到/etc/rc.d/rc.local中

vim /etc/rc.d/rc.local

chkconfig --add fpm

chkconfig fpm on
chmod +x /etc/init.d/php-fpm


vi /etc/nginx/fastcgi_params

将里面内容替换为

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx;
fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;
fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;
# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

 

 

 

vi /etc/nginx/nginx.conf

 

首先将

 

#user  nobody;
改为user  nginx;

 

之后找到
去掉#
 

        location ~ .php$ {
            root           /www;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
            include        fastcgi_params;
        }

 

 server nginxd start
在nginx的根目录下

测试代码
vi index.php
<?php

phpinfo();
?>
192.168.0.206/index.php

可以看到

Server API的工作模式是fpm 这个是指lnmp架构已fpm工作模式工作
但是当nginx作为反向代理的时候 使用的配置文件还是apache的  显示的php的工作模式还是php已模块方式工作的 
Server API Apache 2.0 Handler 因为php文件交给了httpd处理，显示的php信息还是apache的
这个时候请注意
你的php-fpm是不是还在运行

如果出现
iconv.c:1350: undefined reference to `libiconv'错误

tar -zxvf libiconv-1.13.1.tar.gz
cd libiconv-1.13.1
./configure --prefix=/usr/local/libiconv
make
make install

--with-iconv=/usr/local/libiconv

php编译的时候指定路径就OK了

./configure --prefix=/usr/local/php --with-mysql=/usr/local/mysql --with-openssl --with-mysqli=/usr/local/mysql/bin/mysql_config --enable-mbstring --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --enable-sockets --with-apxs2=/usr/local/apache/bin/apxs --with-mcrypt --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-bz2 --enable-maintainer-zts --with-curl --enable-fpm --enable-soap --with-iconv=/usr/local/libiconv  --with-mysqli=/usr/local/mysql/bin/mysql_config  --with-freetype-dir=/usr/local/freetype  --with-gd
这个fpm工作模式的编译选项


最后多说几句话，php5.4以后pdo本身不再是php的分支了已经合并

最后就是nginx反向代理apache，在nginx的配置文件里，吧apache的鉴定端口改为8080
定义server段
server里面可以定义location
静态文件处理交给nginx php处理交给apache

 vi /etc/nginx/nginx.conf

location ~* .(js|css|jpg|jpeg|gif|png)$ {
access_log off;
expires 1d;
}
location ~ ^(.+.php)(.*)$ {

查看phpinfo信息时，Server API Apache 2.0 Handler现在是这个模式运行证明，php交给apache处理了

让nginx反向代理apache时候，需要开启apche的虚拟机和nginx虚拟机，在nginx上也要配置比如我在apache监听的是81，那么反向代理的时候设置成http://127.0.0.1:81

首先配置nginx虚拟机

vi /etc/nginx/nginx.conf

user nginx nginx; #用户和用户组
worker_processes 2;

#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;

events
{
use epoll;epoll模型
worker_connections 65535;最大连接数
}

http {

include mime.types;
default_type application/octet-stream;

#主定义httpd

include /usr/local/nginx/vhost.conf;#引入读取的虚拟机配置文件也可以配置成×.conf也就是读取所有的配置文件，位置也可以自己选择

}

vi /usr/local/nginx/vhost.conf

fastcgi_param PATH_INFO $request_uri;
实现path_info支持

这个测试的时候apache监听是81请注意

server{
listen 80;
server_name www.b.com;
index index.php index.html;
root /www/b.com;

location ~ .php$ {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-Proto https;
"/usr/local/nginx/vhost.conf" 37L, 941C written
[root@localhost ~]# vi /usr/local/nginx/vhost.conf

server{
listen 80;
server_name www.a.com;
root /www/a.com;
index index.php index.html;

location ~ .php$ {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-Proto https;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://127.0.0.1:81; }

location ~ .*.(gif|jpg|jpeg|png|bmp|swf)$ {
expires 1s;
}
location ~ .*.(js|css)?$ {
expires 1s;
}

}

server{
listen 80;
server_name www.b.com;
index index.php index.html;
root /www/b.com;

location ~ .php$ {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-Proto https;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://127.0.0.1:81; }

location ~ .*.(gif|jpg|jpeg|png|bmp|swf)$ {
expires 1s;
}
location ~ .*.(js|css)?$ {
expires 1s;
}

}

a如果你需要配置全局的nginx的请在

/etc/nginx/nginx.conf配置比如日志格式，gzip，各种代理配置

整个下面是apache的配置文件和上面配置的一样，只是

<VirtualHost *:81>
ServerName www.a.com
DocumentRoot "/www/a.com"
<Directory "/www/b.com">
Options none
AllowOverride none
Require all granted
</Directory>
ErrorLog "/var/log/httpd/a.com-error_log"
CustomLog "/var/log/httpd/a.com-access_log" common
</VirtualHost>

<VirtualHost *:81>
ServerName www.b.com
DocumentRoot "/www/b.com"
<Directory "/www/b.com">
Options none
AllowOverride none
Require all granted
</Directory>
ErrorLog "/var/log/httpd/b.com-error_log"
CustomLog "/var/log/httpd/b.com-access_log" common
</VirtualHost>
