一、配置CentOS 第三方yum源（CentOS默認的標準源裏沒有nginx軟件包）

[root@localhost ~]# yum install wget  #安裝下載工具wget
[root@localhost ~]#wget http://www.atomicorp.com/installers/atomic  #下載atomic yum源
[root@localhost ~]#sh ./atomic   #安裝
[root@localhost ~]# yum check-update #更新yum軟件包

二、安裝開發包和庫文件

[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、卸載已安裝的apache、mysql、php

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

四、安裝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、安裝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

#為root賬戶設置密碼
[root@localhost ~]#mysql_secure_installation  #初始化MySQL
Enter current password for root (enter for none):   <---輸入現在的root密碼，因為我們還沒設置，直接回車
Set root password? [Y/n] Y                                    <---是否設定root密碼，當然設置了，輸入Y回車
New password:                                                      <---輸入root密碼，並回車，輸入的過程中不會有任何顯示
Re-enter new password:                                        <---再次輸入root密碼，並回車，輸入的過程中不會有任何顯示
Remove anonymous users? [Y/n] Y                      <---是否刪除匿名用戶，刪除，輸入Y回車
Disallow root login remotely? [Y/n] Y                     <---是否刪禁止root用戶遠程登錄，當然禁止，輸入Y回車
Remove test database and access to it? [Y/n]      <---是否刪除測試數據庫test，看個人喜好

最後出現：Thanks for using MySQL!
MySql密碼設置完成，重新啟動 MySQL：

六、安裝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 

安裝php和所需組件使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)
           ├─18955 php-fpm: pool www
           ├─18956 php-fpm: pool www
           ├─18957 php-fpm: pool www
           ├─18958 php-fpm: pool www
           └─18959 php-fpm: pool www

Dec 23 10:53:59 localhost.localdomain systemd[1]: Starting The PHP FastCGI Process Manager...
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} #將配置文件改為備份文件

#修改nginx配置文件，添加fastcgi支持
[root@localhost ~]# vim /etc/nginx/nginx.conf
vim /etc/nginx/nginx.conf  #編輯
user  nginx  nginx;  #修改nginx運行賬號為：nginx組的nginx用戶
: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 #禁止顯示php版本的信息

九、重啟nginx php-fpm

[root@localhost ~]# systemctl restart nginx.service
[root@localhost ~]# systemctl restart php-fpm.service

十、測試

[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  #設置目錄所有者

#配置防火墻，開啟80端口、3306端口

[root@localhost html]# firewall-cmd --zone=public --add-port=80/tcp --permanent
success
[root@localhost html]# firewall-cmd --zone=public --add-port=3306/tcp --permanent
success
[root@localhost html]# systemctl restart firewalld.service
[root@localhost html]# systemctl enable firewalld.service

在客戶端瀏覽器輸入服務器IP地址，可以看到相關的配置信息！
