centos7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++-33 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 ~]# systemctl start nginx.service
[root@localhost ~]# systemctl status nginx.service
[root@localhost ~]# systemctl enable nginx.service
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.
[root@localhost ~]# 

五、安装mariadb

[root@localhost ~]# yum install mariadb-devel mariadb mariadb-server
[root@localhost ~]# systemctl start mariadb.service
[root@localhost ~]# systemctl status mariadb.service
● mariadb.service - MariaDB database server
   Loaded: loaded (/usr/lib/systemd/system/mariadb.service; disabled; vendor preset: disabled)

[root@localhost ~]# systemctl enable mariadb.service
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service

#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

最后出现：Thanks for using MySQL!
MySql密码设置完成，重新启动 MySQL：

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 ~]# systemctl start php-fpm.service
[root@localhost ~]# systemctl status php-fpm.service
● php-fpm.service - The PHP FastCGI Process Manager
   Loaded: loaded (/usr/lib/systemd/system/php-fpm.service; disabled; vendor preset: disabled)
   Active: active (running) since Sat 2017-12-23 10:53:59 HKT; 4s ago
 Main PID: 18953 (php-fpm)
   Status: "Ready to handle connections"
   CGroup: /system.slice/php-fpm.service
           ├─18953 php-fpm: master process (/etc/php-fpm.conf)

           ├─18957 php-fpm: pool www
           ├─18958 php-fpm: pool www
           └─18959 php-fpm: pool www

Dec 23 10:53:59 localhost.localdomain systemd[1]: Started The PHP FastCGI Process Manager.
[root@localhost ~]# 
[root@localhost ~]# systemctl enable php-fpm.service
Created symlink from /etc/systemd/system/multi-user.target.wants/php-fpm.service to /usr/lib/systemd/system/php-fpm.service.
[root@localhost ~]# 

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
[root@localhost ~]# vim /etc/nginx/nginx.conf
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]# 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 nginx]#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 ~]# systemctl restart nginx.service
[root@localhost ~]# systemctl restart php-fpm.service

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 html]# firewall-cmd --zone=public --add-port=/tcp --permanent
success
[root@localhost html]# firewall-cmd --zone=public --add-port=/tcp --permanent
success
[root@localhost html]# systemctl restart firewalld.service
[root@localhost html]# systemctl enable firewalld.service

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
