  1. 下载mysql到/usr/local/src/
cd /usr/local/src/
wget http://syslab.comsenz.com/downloads/linux/mysql-5.1.40-linux-i686-icc-glibc23.tar.gz
  1. 解压
[root@localhost src]# tar zxvf /usr/local/src/mysql-5.1.40-linux-i686-icc-glibc23.tar.gz
  1. 把解压完的数据移动到/usr/local/mysql
[root@localhost src]# mv mysql-5.1.40-linux-i686-icc-glibc23 /usr/local/mysql
  1. 建立mysql用户
[root@localhost src]# useradd -s /sbin/nologin mysql
  1. 初始化数据库
[root@localhost src]# cd /usr/local/mysql
[root@localhost mysql]# mkdir -p /data/mysql ; chown -R mysql:mysql /data/mysql
[root@localhost mysql]# ./scripts/mysql_install_db --user=mysql --datadir=/data/mysql

Installing MySQL system tables..../bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory

yum install libaio 


---------------------------------------------------------------------------------------
./bin/mysqld  --initialize --user=mysql --datadir=/data/mysql //MYSQL 5.6/5.7 后 新版的初使化方法
注意,这一步最后一行会有一个提示
[Note] A temporary password is generated for root@localhost: B*s1i(*,kXwg
最后面的字符串为root密码。
./bin/mysql_ssl_rsa_setup --datadir=/data/mysql
4. 拷贝配置文件和启动脚本
cp support-files/my-default.cnf  /etc/my.cnf   //老版本为: cp support-files/my-large.cnf /etc/my.cnf

----------------------------------------------------------------------------------

cp support-files/my-large.cnf /etc/my.cnf
vim /etc/my.cnf //编辑或者修改   
[mysqld]   //在这里修改
basedir = /usr/local/mysql
datadir = /data/mysql
port = 3306
socket = /tmp/mysql.sock



cp support-files/mysql.server /etc/init.d/mysqld
chmod 755 /etc/init.d/mysqld
vim /etc/init.d/mysqld   //编辑或者修改
basedir=/usr/local/mysql
datadir=/data/mysql


5. 启动服务
/etc/init.d/mysqld start //路径方式启动mysql
chkconfig -add mysqld //添加进service 列表,可用service 来启动。
chkconfig mysqld on //服务默认开启
service mysqld start //用 service 来启动

6. 设置root密码
使用初始化密码登录
/usr/local/mysql/bin/mysql -uroot -p'B*s1i(*,kXwg'  //进入后直接设置密码 老版密码为空 不用-p
mysql>set password = password('mypass');   //一定要设置一下新密码
退出来,再使用新的密码登录就可以了
安装需要的包:
64位系统选择:
rpm -ivh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm //EPEL源
yum install -y gcc
yum install -y libxml2-devel
yum install -y openssl openssl-devel
yum install -y bzip2 bzip2-devel
yum install -y libpng libpng-devel
yum install -y libjpeg-turbo-devel 
yum install -y freetype freetype-devel
yum install -y libcurl-devel
yum install -y libtool-ltdl-devel
yum install -y  libmcrypt-devel          // 这个需要安装epel源

yum -y install pcre-devel

  1. 下载php
[rot@localhost httpd-2.2.24]# cd /usr/local/src
[root@localhost src]# wget http://am1.php.net/distributions/php-5.3.27.tar.gz
  1. 解压php
[root@localhost src]# tar zxf php-5.3.27.tar.gz
  1. 创建相关账户
[root@localhost src]# useradd -s /sbin/nologin php-fpm
  1. 配置编译参数
[root@localhost src]# cd php-5.3.27
[root@localhost php-5.3.27]# ./configure 
--prefix=/usr/local/php 
--with-config-file-path=/usr/local/php/etc 
--enable-fpm 
--with-fpm-user=php-fpm 
--with-fpm-group=php-fpm 
--with-mysql=/usr/local/mysql 
--with-mysql-sock=/tmp/mysql.sock 
--with-libxml-dir 
--with-gd 
--with-jpeg-dir 
--with-png-dir 
--with-freetype-dir 
--with-iconv-dir 
--with-zlib-dir 
--with-mcrypt 
--enable-soap 
--enable-gd-native-ttf 
--enable-ftp 
--enable-mbstring 
--enable-exif 
--enable-zend-multibyte 
--disable-ipv6 
--with-pear 
--with-curl 
--with-openssl

该过程中,如果出现如下错误,请按照阿铭给出的解决办法解决,如果出现的错误阿铭并没有写出来,请参考上一章LAMP的php安装步骤(http://study.lishiming.net/chapter17.html#php)

错误信息:

configure: error: Please reinstall the libcurl distribution -
    easy.h should be in <curl-dir>/include/curl/

解决办法:

yum install -y libcurl-devel
  1. 编译php
[root@localhost  php-5.3.27]# make

在这一步,你通常会遇到一些错误,没有关系,遇到错误是好事,这样可以增加你处理问题的经验。阿铭同样也遇到了错误:

/usr/bin/ld: cannot find -lltdl
collect2: ld returned 1 exit status
make: *** [sapi/fpm/php-fpm] 错误 1

阿铭是这样解决的:

yum install -y libtool-ltdl-devel
  1. 安装php
[root@localhost  php-5.3.27]# make install

以上每一个步骤,如果没有完全执行正确,那么下一步是无法进行的,是否还记得判断执行是否正确的方法? 使用 echo $? 看结果是否为 “0” , 如果不是,就是没有执行正确。

  1. 修改配置文件
cp php.ini-production /usr/local/php/etc/php.ini
vim /usr/local/php/etc/php-fpm.conf

把如下内容写入该文件:

[global]
pid = /usr/local/php/var/run/php-fpm.pid
error_log = /usr/local/php/var/log/php-fpm.log
[www]
listen = /tmp/php-fcgi.sock
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024

保存配置文件后,检验配置是否正确的方法为:

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

如果出现诸如 “test is successful” 字样,说明配置没有问题。

  1. 启动php-fpm
cp /usr/local/src/php-5.3.27/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
chmod 755 /etc/init.d/php-fpm
service php-fpm start

如果想让它开机启动,执行:

chkconfig php-fpm on

检测是否启动:

ps aux |grep php-fpm

看看是不是有很多个进程(大概20多个)。

安装nginx

Nginx官方网站(http://nginx.org), 从官方网站可以看到nginx更新速度很快,这也反映了一个事实,目前使用nginx跑网站的公司或者个人越来越多。当前最新版本为1.5, 但是阿铭不建议你安装这么新的,因为它还太新,难免会有一些bug或者漏洞,所以阿铭建议你安装1.4版本的nginx.

(近期nginx报出一个安全漏洞,影响版本很广 CVE-2013-4547,所以之前的老版本都需要升级一下, 1.4.4, 1.5.7以及往后版本没有问题)

  1. 下载nginx
cd /usr/local/src/
wget http://nginx.org/download/nginx-1.4.4.tar.gz
  1. 解压nginx
tar zxvf nginx-1.4.4.tar.gz
  1. 配置编译参数
cd nginx-1.4.4
./configure 
--prefix=/usr/local/nginx 
--with-http_realip_module 
--with-http_sub_module 
--with-http_gzip_static_module 
--with-http_stub_status_module  
--with-pcre
  1. 编译nginx
make
  1. 安装nginx
make install

因为nginx比较小,所以很快就会安装完,而且也不会出什么错误,如果出错了,到阿铭论坛(http://www.aminglinux.com/bbs/forum-40-1.html)发帖求助阿铭吧。

  1. 编写nginx启动脚本,并加入系统服务
vim /etc/init.d/nginx

写入如下内容:

#!/bin/bash
# chkconfig: - 30 21
# description: http service.
# Source Function Library
. /etc/init.d/functions
# Nginx Settings

NGINX_SBIN="/usr/local/nginx/sbin/nginx"
NGINX_CONF="/usr/local/nginx/conf/nginx.conf"
NGINX_PID="/usr/local/nginx/logs/nginx.pid"
RETVAL=0
prog="Nginx"

start() {
        echo -n $"Starting $prog: "
        mkdir -p /dev/shm/nginx_temp
        daemon $NGINX_SBIN -c $NGINX_CONF
        RETVAL=$?
        echo
        return $RETVAL
}

stop() {
        echo -n $"Stopping $prog: "
        killproc -p $NGINX_PID $NGINX_SBIN -TERM
        rm -rf /dev/shm/nginx_temp
        RETVAL=$?
        echo
        return $RETVAL
}

reload(){
        echo -n $"Reloading $prog: "
        killproc -p $NGINX_PID $NGINX_SBIN -HUP
        RETVAL=$?
        echo
        return $RETVAL
}

restart(){
        stop
        start
}

configtest(){
    $NGINX_SBIN -c $NGINX_CONF -t
    return 0
}

case "$1" in
  start)
        start
        ;;
  stop)
        stop
        ;;
  reload)
        reload
        ;;
  restart)
        restart
        ;;
  configtest)
        configtest
        ;;
  *)
        echo $"Usage: $0 {start|stop|reload|restart|configtest}"
        RETVAL=1
esac

exit $RETVAL

保存后,更改权限:

chmod 755 /etc/init.d/nginx
chkconfig --add nginx

如果想开机启动,请执行:

chkconfig nginx on
  1. 更改nginx配置

首先把原来的配置文件清空:

> /usr/local/nginx/conf/nginx.conf

“>” 这个符号之前阿铭介绍过,为重定向的意思,单独用它,可以把一个文本文档快速清空。

vim /usr/local/nginx/conf/nginx.conf

写入如下内容:

user nobody nobody;
worker_processes 2;
error_log /usr/local/nginx/logs/nginx_error.log crit;
pid /usr/local/nginx/logs/nginx.pid;
worker_rlimit_nofile 51200;

events
{
    use epoll;
    worker_connections 6000;
}

http
{
    include mime.types;
    default_type application/octet-stream;
    server_names_hash_bucket_size 3526;
    server_names_hash_max_size 4096;
    log_format combined_realip '$remote_addr $http_x_forwarded_for [$time_local]'
    '$host "$request_uri" $status'
    '"$http_referer" "$http_user_agent"';
    sendfile on;
    tcp_nopush on;
    keepalive_timeout 30;
    client_header_timeout 3m;
    client_body_timeout 3m;
    send_timeout 3m;
    connection_pool_size 256;
    client_header_buffer_size 1k;
    large_client_header_buffers 8 4k;
    request_pool_size 4k;
    output_buffers 4 32k;
    postpone_output 1460;
    client_max_body_size 10m;
    client_body_buffer_size 256k;
    client_body_temp_path /usr/local/nginx/client_body_temp;
    proxy_temp_path /usr/local/nginx/proxy_temp;
    fastcgi_temp_path /usr/local/nginx/fastcgi_temp;
    fastcgi_intercept_errors on;
    tcp_nodelay on;
    gzip on;
    gzip_min_length 1k;
    gzip_buffers 4 8k;
    gzip_comp_level 5;
    gzip_http_version 1.1;
    gzip_types text/plain application/x-javascript text/css text/htm application/xml;

server
{
    listen 80;
    server_name localhost;
    index index.html index.htm index.php;
    root /usr/local/nginx/html;

    location ~ .php$ {
        include fastcgi_params;
        fastcgi_pass unix:/tmp/php-fcgi.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
    }

}

}

保存配置后,先检验一下配置文件是否有错误存在:

/usr/local/nginx/sbin/nginx  -t

如果显示内容如下,则配置正确,否则需要根据错误提示修改配置文件:

nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

启动nginx:

service nginx start

如果不能启动,请查看 “/usr/local/nginx/logs/error.log” 文件,检查nginx是否启动:

ps aux |grep nginx

看是否有进程。

测试是否解析php文件

创建测试文件:

vim /usr/local/nginx/html/2.php

内容如下:

<?php
    echo "测试php是否解析";
?>

测试:

[root@localhost nginx]# curl localhost/2.php
测试php是否解析[root@localhost nginx]#

nginx+php测试时显示 502 bad gateway的解决方法
