centos6.8安装lnmp

一、配置CentOS 第三方yum源（CentOS默认的标准源里没有nginx软件包）

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

二、安装开发包和库文件

[root@localhost ~]# yum -y install ntp make openssl openssl-devel pcre pcre-devel libpng libpng-devel libjpeg-6b libjpeg-devel-6b freetype freetype-devel gd gd-devel zlib zlib-devel gcc gcc-c++ libXpm libXpm-devel ncurses ncurses-devel libmcrypt libmcrypt-devel libxml2 libxml2-devel imake autoconf automake screen sysstat compat-libstdc++- curl curl-devel

三、卸载已安装的apache、mysql、php

[root@localhost ~]# yum remove httpd
[root@localhost ~]# yum remove mysql
[root@localhost ~]# yum remove php

四、安装nginx

[root@localhost ~]# yum install nginx -y
[root@localhost ~]# service nginx start
[root@localhost ~]# chkconfig --levels 235 nginx on  #设置2、3、5级别开机启动

五、安装mysql

[root@localhost ~]# yum install mysql mysql-server mysql-devel -y
[root@localhost ~]# service mysqld start
[root@localhost ~]#  chkconfig --levels 235 mysqld on

#为root账户设置密码
[root@localhost ~]#mysql_secure_installation  #初始化MySQL
Enter current password for root (enter for none):   <---输入现在的root密码，因为我们还没设置，直接回车
Set root password? [Y/n] Y                                    <---是否设定root密码，当然设置了，输入Y回车
New password:                                                      <---输入root密码，并回车，输入的过程中不会有任何显示
Re-enter new password:                                        <---再次输入root密码，并回车，输入的过程中不会有任何显示
Remove anonymous users? [Y/n] Y                      <---是否删除匿名用户，删除，输入Y回车
Disallow root login remotely? [Y/n] Y                     <---是否删禁止root用户远程登录，当然禁止，输入Y回车
Remove test database and access to it? [Y/n]      <---是否删除测试数据库test，看个人喜好
Reload privilege tables now? [Y/n] Y                    <---刷新权限，输入Y回车
最后出现：Thanks for using MySQL!
MySql密码设置完成，重新启动 MySQL：

[root@localhost ~]#/etc/init.d/mysqld start  #启动
[root@localhost ~]# /etc/init.d/mysqld status
[root@localhost ~]# chkconfig mysqld on

六、安装php

[root@localhost ~]# yum -y install php php-cli php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-mssql php-snmp php-soap 

安装php和所需组件使PHP支持MySQL、FastCGI模式

[root@localhost ~]# yum install  php-tidy php-common php-devel php-fpm php-mysql -y
[root@localhost ~]# service php-fpm start
Starting php-fpm:                                          [  OK  ]
[root@localhost ~]# chkconfig --levels 235 php-fpm on

七、配置nginx支持php

[root@localhost ~]# cp /etc/nginx/nginx.conf{,.bak}  #将配置文件改为备份文件

#修改nginx配置文件，添加fastcgi支持
vim /etc/nginx/nginx.conf  #编辑
user  nginx  nginx;  #修改nginx运行账号为：nginx组的nginx用户
:wq!    #保存退出

[root@localhost nginx]# cp /etc/nginx/conf.d/default.conf{,.bak}

[root@localhost nginx]# vim /etc/nginx/conf.d/default.conf 

    location / {
        root   /usr/share/nginx/html;
        index  index.php index.html index.htm;   #增加index.php
    }
      location ~ \.php$ {
        root           /usr/share/nginx/html;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/html$fastcgi_script_name;
        include        fastcgi_params;
    }

八、配置php

[root@localhost nginx]# cp /etc/php.ini{,.bak}
[root@localhost ~]# vim /etc/php.ini
expose_php = Off #禁止显示php版本的信息

九、重启nginx php-fpm

[root@localhost nginx]# service nginx restart
Stopping nginx:                                            [  OK  ]
Starting nginx:                                            [  OK  ]
[root@localhost nginx]# service php-fpm restart
Stopping php-fpm:                                          [  OK  ]
Starting php-fpm:           

十、测试

[root@localhost ~]# cd /usr/share/nginx/html/
[root@localhost html]# vim  index.php
<?php
     phpinfo();
?>
[root@localhost html]# chown nginx.nginx /usr/share/nginx/html/ -R  #设置目录所有者

#配置防火墙，开启80端口、3306端口
[root@localhost ~]vi /etc/sysconfig/iptables
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT（允许80端口通过防火墙）
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT（允许3306端口通过防火墙）
特别提示：很多网友把这两条规则添加到防火墙配置的最后一行，导致防火墙启动失败，正确的应该是添加到默认的22端口这条规则的下面
添加好之后防火墙规则如下所示：
#########################################################
# 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 -mstate --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A INPUT -mstate --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
######
[root@localhost ~]/etc/init.d/iptables restart  #最后重启防火墙使配置生效
 

在客户端浏览器输入服务器IP地址，可以看到相关的配置信息！

备注

nginx默认站点目录是：/usr/share/nginx/html/
权限设置：chown nginx.nginx/usr/share/nginx/html/ -R
MySQL数据库目录是：/var/lib/mysql
权限设置：chown mysql.mysql -R /var/lib/mysql
