CentOs 安装 Nginx + php + mysql (推荐方式)

本文全部采用yum进行安装, CentOs6.5 mini 版本。

一、更改yum源为网易的源加快速度， 如果是从网易镜像下载的安装包，直接注释这几项也可以

vim /etc/yum.repos.d/CentOS-Base.repo

# 需要更改的项
[base]
baseurl = http://mirror.163.com/centos/$releasever/os/$basearch/

[updates]
baseurl=http://mirror.163.com/centos/$releasever/updates/$basearch/

[extras]
baseurl=http://mirror.163.com/centos/$releasever/extras/$basearch/

[centosplus]
baseurl=http://mirror.163.com/centos/$releasever/centosplus/$basearch/

[contrib]
baseurl=http://mirror.163.com/centos/$releasever/contrib/$basearch/

二、安装依赖库

yum -y install gcc gcc-c++ autoconf 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 nss_ldap openldap-clients openldap-servers

注：lib【生产环境库】, lib-dev【开发环境库】, lib-gdb【调试环境库】，我们安装生产环境库与开发环境库。

三、由于centos没有默认的nginx软件包，解决方法是：

1.启用REHL的附件包 （推荐）

# 32位
rpm -Uvh ftp://ftp.univie.ac.at/systems/linux/fedora/epel/6/i386/epel-release-6-8.noarch.rpm

# 64位
rpm -Uvh ftp://ftp.univie.ac.at/systems/linux/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm
# 如果版本不对，打开列表查看最新版本号

如果既想获得 RHEL 的高质量、高性能、高可靠性，又需要方便易用(关键是免费)的软件包更新功能，那么 Fedora Project 推出的 EPEL(Extra Packages for Enterprise Linux)正好适合你。EPEL(http://fedoraproject.org/wiki/EPEL) 是由 Fedora 社区打造，为 RHEL 及衍生发行版如 CentOS、Scientific Linux 等提供高质量软件包的项目。

2. 应用第三方yum源 （不推荐）

yum install wget #安装下载工具wget
wget http://www.atomicorp.com/installers/atomic #下载atomic yum源
sh ./atomic #安装
yum check-update #更新yum软件包

四、开始一键安装Nginx, Mysql, PHP

yum -y install nginx mysql mysql-server mysql-dev php-mysql php-fpm php-cli php-pdo  php-mcrypt php-mbstring php-gd php-tidy php-xml php-xmlrpc php-pear php-pecl-memcache php-eaccelerator

五、设置启动与开机启动

启动
service mysqld start
service php-fpm start
service nginx start

设置开机启动
chkconfig --level 345 mysqld on
chkconfig --level 345 php-fpm on
chkconfig --level 345 nginx on

配置文件都在 /etc 下

六、配置nginx.conf, 能够使用php

vi /etc/nginx/nginx.conf

worker_processes  5;

keepalive_timeout  2;

server {
        listen       80;
        server_name  localhost; # 这里一定要设置，否则不能支持php
 
        #charset koi8-r;
 
        #access_log  logs/host.access.log  main;
        root   /usr/share/nginx/html; # 放到该层级让下面的location继承
 
        location / {
            index  index.php index.html index.htm;
        }
 
        error_page  404  /404.html;
        location = /404.html {

        }
 
        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
        }
 
        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ .php$ {
        #    proxy_pass   http://127.0.0.1;
        #}
 
        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        location ~ .php$ {
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $ducoment_root$fastcgi_script_name;
            include        fastcgi_params;
        }
 
        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        location ~ /.ht {
            deny  all;
        }
}

重启nginx

service nginx restart

5. 写一个php测试文件

<?php
phpinfo();
?>

如果用IP访问不了服务器，则需要配置

1. 防火墙配置， 开放80,3306端口：

vi /etc/sysconfig/iptables

# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT

/etc/init.d/iptables restart  #最后重启防火墙使配置生效

2、关闭SELINUX
vi /etc/selinux/config

#SELINUX=enforcing #注释掉
#SELINUXTYPE=targeted #注释掉
SELINUX=disabled #增加

:wq 保存，关闭
shutdown -r now #重启系统
