linux-------lnmp安装

一 环境准备

 

1.系统环境

[root@web02 ~]# cat /etc/redhat-release 
CentOS release 6.5 (Final)
[root@web02 ~]# uname -r
2.6.32-431.el6.x86_64

 

 

 2.关闭selinux iptables

[root@web02 ~]# getenforce 
Disabled
[root@web02 ~]# /etc/init.d/iptables status
iptables: Firewall is not running.

 

 

3.安装的位置目录，存放软件的目录

mkdir -p /application/   /server/tools

 

 

4.软件版本

mysql-5.6.34    　　　　#二进制编译安装

php-5.5.32　　　　　　#编译安装

wordpress-4.7  

nginx-1.12.2　　　　     #编译安装

 

二 部署nginx

 

1  创建用户

[root@web02 tools]# useradd www -s /sbin/nologin -M

 

2 解压，编译安装

tar -xf nginx-1.12.2.tar.gz
cd nginx-1.12.2
./configure --prefix=/application/nginx-1.12.2 --user=www --group=www --with-http_ssl_module --with-http_stub_status_module
make && make install 

 

3 创建软连接

ln -s /application/nginx-1.12.2 /application/nginx

 

4 启动 精简配置文件

[root@web02 nginx-1.12.2]# /application/nginx/sbin/nginx -t　　　　#检查配置文件
nginx: the configuration file /application/nginx-1.12.2/conf/nginx.conf syntax is ok
nginx: configuration file /application/nginx-1.12.2/conf/nginx.conf test is successful
[root@web02 nginx-1.12.2]# /application/nginx/sbin/nginx　　　　　　#启动

 

 

[root@web02 nginx-1.12.2]# grep -Ev "#|^$" /application/nginx/conf/nginx.conf.default   > /application/nginx/conf/nginx.conf

[root@web02 nginx-1.12.2]# cat /application/nginx/conf/nginx.conf
worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    server {
        listen       80;
        server_name  localhost;
        location / {
            root   html;
            index  index.html index.htm;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
}

 

 

 

三 部署mysql（二进制）

 

mysql官方下载链接地址：ftp://ftp.jaist.ac.jp/pub/mysql/Downloads/MySQL-5.6/

1.下载mysql

mysql-5.6.34-linux-glibc2.5-x86_64.tar.gz

 

2.解压安装

tar xf mysql-5.6.34-linux-glibc2.5-x86_64.tar.gz

mv mysql-5.6.34-linux-glibc2.5-x86_64 /application/mysql-5.6.34

ln -sf /application/mysql-5.6.34/ /application/mysql

 

 

3.创建用户

useradd mysql -M -s /sbin/nologin 

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

 

 

4.初始化数据库

/application/mysql/scripts/mysql_install_db --basedir=/application/mysql --datadir=/application/mysql/data/ --user=mysql

 

 

5.启动mysql服务

 

cp /application/mysql/support-files/mysql.server /etc/init.d/mysqld
sed -ri 's#/usr/local#/application#g' /etc/init.d/mysqld /application/mysql/bin/mysqld_safe
cp /application/mysql/support-files/my-default.cnf /etc/my.cnf
/etc/init.d/mysqld start

 

 

6.设置密码

/application/mysql/bin/mysqladmin -uroot password "oldboy123"
/application/mysql/bin/mysql -uroot -poldboy123

 

 

7.设置MySQL开机自启动

chkconfig --add mysqld

chkconfig mysqld on

 

 

8.配置环境变量

echo 'export PATH=/application/mysql/bin:$PATH' >>/etc/profile 

source /etc/profile

 

 

9.清理无用的MYsql用户及库

mysql>  select user,host from mysql.user;
+------+-----------+
| user | host      |
+------+-----------+
| root | 127.0.0.1 |
| root | ::1       |
|      | localhost |
| root | localhost |
|      | web02     |
| root | web02     |
+------+-----------+
6 rows in set (0.00 sec)

 

 

mysql> drop user "root"@"::1";
Query OK, 0 rows affected (0.00 sec)

mysql> drop user ""@"localhost";
Query OK, 0 rows affected (0.00 sec)

mysql> drop user ""@"web02";
Query OK, 0 rows affected (0.00 sec)

mysql> drop user "root"@"web02";
Query OK, 0 rows affected (0.00 sec)

mysql>  select user,host from mysql.user;
+------+-----------+
| user | host      |
+------+-----------+
| root | 127.0.0.1 |
| root | localhost |
+------+-----------+
2 rows in set (0.00 sec)

 

四 php编译安装

FastCGI：
FastCGI是一个可伸缩地，高速地在HTTP服务器和动态脚本语言间通信的接口（在LINUX下 FastCGI接口即为socket，这个socke可以是文件的socket，也可以是IP socket），主要的优点是把动态语言和HTTP服务器分离开来，多数流行的HTTP服务器都支持FastCGI，包括Apache nginx lighttpd。

同时，FastCGI也是被许多的脚本语言支持，例如当前比较流行的PHP，FastCGI接口采用的是C/S架构，可以将HTTP服务器和脚本解析服务器分开，同时还能在脚本解析服务器上启动一个或多个脚本来解析守护进程，HTTP服务器遇到动态程序时，可以将其直接交付给FastCGI进程来执行，然后将得到的结果返回给浏览器。这种方式可以让HTTP服务器专一地处理静态请求，或者将动态脚本服务器的结果返回给客户端，这在很大的程度上提高整个应用系统的性能

FastCGI的重要特点：
1）http服务器和动态脚本语言通信的接口和工具
2）可把动态语言解析和HTTP服务器分离开
3）Apache nginx lighttpd，以及多个动态语言支持FastCGI
4）FastCGI接口采用的是C/S架构 ，分为客户端和服务端
5）HPH动态语言服务器可以启动多个FastCGI的守护进程
6）http服务器通过（例如nginx fastcgi_pass） FastCGI客户端和动态语言FastCGI服务器端通信（例如php-fpm）

1.安装依赖包

yum install -y zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel libmcrypt-devel mhash mcrypt

2.安装libiconv软件

tar zxf libiconv-1.14.tar.gz
cd libiconv-1.14
./configure --prefix=/usr/local/libiconv
make
make install
cd ../

3.下载php包

php-5.5.32.tar.gz

4.安装php包

cd /server/tools/
tar xf php-5.5.32.tar.gz
cd php-5.5.32

./configure 
--prefix=/application/php-5.5.32 
--with-mysql=/application/mysql-5.6.34 
--with-pdo-mysql=mysqlnd 
--with-iconv-dir=/usr/local/libiconv 
--with-freetype-dir 
--with-jpeg-dir 
--with-png-dir 
--with-zlib 
--with-libxml-dir=/usr 
--enable-xml 
--disable-rpath 
--enable-bcmath 
--enable-shmop 
--enable-sysvsem 
--enable-inline-optimization 
--with-curl 
--enable-mbregex 
--enable-fpm 
--enable-mbstring 
--with-mcrypt 
--with-gd 
--enable-gd-native-ttf 
--with-openssl 
--with-mhash 
--enable-pcntl 
--enable-sockets 
--with-xmlrpc 
--enable-soap 
--enable-short-tags 
--enable-static 
--with-xsl 
--with-fpm-user=www 
--with-fpm-group=www 
--enable-ftp 
--enable-opcache=no

防错(以下信息可以不进行配置了)

ln -s /application/mysql/lib/libmysqlclient.so.18 /usr/lib64/
touch ext/phar/phar.phar
make
make install
ln -s /application/php-5.5.32/ /application/php

5.配置php

cp php.ini-production /application/php-5.5.32/lib/php.ini

cd /application/php/etc/

cp php-fpm.conf.default php-fpm.conf

6.启动php程序服务

/application/php/sbin/php-fpm

[root@web02 etc]# netstat -lntup|grep php
tcp        0      0 127.0.0.1:9000              0.0.0.0:*                   LISTEN      128497/php-fpm 

7.修改nginx支持php解析

[root@web02 html]# cat ../conf/nginx.conf
worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    server {
        listen       80;
        server_name  localhost;
       root         html;
    index        index.php index.html index.htm;
    location ~* .*.(php|php5)?$ {
       fastcgi_pass   127.0.0.1:9000;
       fastcgi_index  index.php;
           include       fastcgi.conf;
    }
    }
}

8.php 测试页面

[root@web02 html]# cat test_info.php 
<?php 
        phpinfo(); 
?> 

9.编写mysql的测试页面

[root@web02 html]# cat mysql_info.php 
<?php
//$link_id=mysql_connect('主机名','用户','密码');
//mysql -u用户 -p密码 -h 主机
$link_id=mysql_connect('localhost','root','oldboy123') or mysql_error();
if($link_id){
echo "mysql successful by oldboy !
";
}else{
echo mysql_error();
}
?>

10. 编写php 启动脚本

打开配置文件 （/application/php/etc/php-fpm.conf）

打开 注释    pid = run/php-fpm.pid 

编写/etc/init.d/php-fpm

#!/bin/bash
# php-fpm startup script for the php-fpm 
# php-fpm version:5.5.32
# chkconfig: - 85 15
# description: php-fpm is very good
# processname: php-fpm
# pidfile: /application/php/var/run/php-fpm.pid
# config: /application/php/etcphp-fpm.conf
  
php_command=/application/php/sbin/php-fpm
php_config=/application/php/etc/php-fpm.conf
php_pid=/application/php/var/run/php-fpm.pid

RETVAL=0
prog="php-fpm"
  
#start function
php_fpm_start() {
    /application/php/sbin/php-fpm
}
  
start(){
    if [ -e $php_pid  ]
    then
    echo "php-fpm already start..."
    exit 1
    fi
    php_fpm_start
}
  
stop(){
    if [ -e $php_pid ]
    then
    parent_pid=`cat $php_pid`
    all_pid=`ps -ef | grep php-fpm | awk '{if('$parent_pid' == $3){print $2}}'`
    for pid in $all_pid
    do
            kill $pid
        done
        kill $parent_pid
    fi
    #exit 1
}

restart(){
    stop
    sleep 3
    start
}

case "$1" in
        start)
      start
    ;;
    stop)
      stop
    ;;
        restart)
          restart
                ;;
        * )
    echo "Usage: $prog [start|stop|restart]"
      exit 1
       ;;
esac

## 添加执行权限 
chmod a+x /etc/init.d/php-fpm

## 加入服务
chkconfig --add php-fpm

## 开机自启 
chkconfig php-fpm on

五 安装wordpress

1.下载软件

wordpress-4.7.3-zh_CN.tar.gz

2. 安装 wordpress

tar xf wordpress-4.7.3-zh_CN.tar.gz 
mv wordpress/* /application/nginx/html/
chown -R www.www /application/nginx/html/

3.创建库 并授权

create database wordpress;

grant all on wordpress.* to 'wordpress'@'localhost' identified by 'oldboy123';
