首先配置防火墙 

CentOS 7.0默认使用的是firewall作为防火墙 

1.关闭firewall：

  1. systemctl stop firewalld.service #停止firewall 
  2.   systemctl disable firewalld.service #禁止firewall开机启动

    或者开启某端口 
    firewall-cmd --permanent --add-port=50000/tcp
    用该命令查询firewall-cmd --permanent --query-port=50000/tcp
    如果是yes就是添加成功，如果是no就是没成功
    成功后重载防火墙firewall-cmd --reload
  1. 2.关闭SELINUX
  1. vi /etc/selinux/config 
  2. #SELINUX=enforcing #注释掉 
  3. SELINUX=disabled #增加 
  4. :wq! #保存退出 
  5. setenforce 0 #使配置立即生效

Lnmp安装

1.安装nginx

  1. yum install yum-priorities -y 
  2. wget http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm 
  3. rpm -ivh nginx-release-centos-7-0.el7.ngx.noarch.rpm 
  4. yum install nginx

2.启动nginx

  1. systemctl start nginx.service #启动nginx 
  2. systemctl stop nginx.service #停止 
  3. systemctl restart nginx.service #重启 
  4. systemctl enable nginx.service #设置开机启动

3.更改nginx端口号（根据自己需求）

  1. cd /etc/nginx/conf.d/ 
  2. vim default.conf 
  3. 把listen 80改成listen 81 
  4. 然后重启nginx 
  5. systemctl restart nginx.service #重启nginx

4.访问http://ip:81即可看到nginx首页

5.下一步安装PHP-fpm

  1. yum install php-fpm 
  2. 安装完毕后
  3. systemctl start php-fpm.service #启动php-fpm 
  4. systemctl enable php-fpm.service #设置开机启动

6.更改nginx配置文件识别php  vi /etc/nginx/conf.d/default.conf，把之前的#给去掉就可以了，顺手改一下fastcgi_param

  1. location ~ \.php$ { 
  2.     root      html; 
  3.     fastcgi_pass  127.0.0.1:9000; 
  4.     fastcgi_index index.php; 
  5.     fastcgi_param SCRIPT_FILENAME /usr/share/nginx/html/$fastcgi_script_name; 
  6.     include    fastcgi_params; 
  7.   }

7.访问test.php

  1. 在 /usr/share/nginx/html中新建一个test.php <?php echo 123;?>
  3. 访问http://ip:81/test.php即可看到nginx中的php页面

8.负载配置

进入 vi /etc/nginx/conf.d/default.conf

  1. upstream site{ 
  2.       server 172.16.170.138; 
  3.       server 172.16.170.139; 
  4.   } 
  5.   server { 
  6.     listen    80; 
  7.     server_name ieccohomo.com; 
  9.     #charset koi8-r; 
  10.     #access_log /var/log/nginx/log/host.access.log main; 
  12.     location / { 
  13.       root  /usr/share/nginx/html; 
  14.       index index.html index.htm; 
  15.       proxy_pass http://ieccohomo.com; 
  16.     }

9.域名修改  把上面(ieccohomo.com)site,localhost改为www.a.com

Lamp安装

1.安装apache

  1. yum install httpd #根据提示，输入Y安装即可成功安装 
  2.   systemctl start httpd.service #启动apache 
  3.   systemctl stop httpd.service #停止apache 
  4.   systemctl restart httpd.service #重启apache 
  5.   systemctl enable httpd.service #设置apache开机启动

2.安装mariadb（MySQL）

  1. yum install mariadb mariadb-server #询问是否要安装，输入Y即可自动安装,直到安装完成 
  2.   systemctl start mariadb.service #启动MariaDB 
  3.   systemctl stop mariadb.service #停止MariaDB 
  4.   systemctl restart mariadb.service #重启MariaDB 
  5.   systemctl enable mariadb.service #设置开机启动

3.修改mysql密码，安装后默认为空

修改mysql密码：set password for \’root\’@\’localhost\’=password \’root\’;

mysql授权远程连接（navicat等）： grant all on *.* to root identified by \’root\’; 

4.安装PHP以及组件，使PHP支持 MariaDB

  1. yum install php php-mysql php-gd libjpeg* php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-bcmath php-mhash 
  2. #这里选择以上安装包进行安装，根据提示输入Y回车 
  3. systemctl restart mariadb.service #重启MariaDB 
  4. systemctl restart httpd.service #重启apache

5.访问测试

  1. cd /var/www/html
  2. vi index.php #输入下面内容
  3.  <?php
  4.   phpinfo();
  5. ?>
  6. :wq! #保存退出

在客户端浏览器输入服务器IP地址端口号
