centos7.0之Lnmp和Lamp详细介绍

centos7.0之Lnmp和Lamp

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:

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

2.关闭SELINUX

  vi /etc/selinux/config   #SELINUX=enforcing #注释掉   SELINUX=disabled #增加   :wq! #保存退出   setenforce 0 #使配置立即生效  

Lnmp安装

1.安装nginx

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

2.启动nginx

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

3.更改nginx端口号(根据自己需求)

  cd /etc/nginx/conf.d/   vim default.conf   把listen 80改成listen 81   然后重启nginx   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

  yum install php-fpm   安装完毕后  systemctl start php-fpm.service #启动php-fpm   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

   location ~ .php$ {       root      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;     }   

7.访问test.php

  在 /usr/share/nginx/html中新建一个test.php <?php echo 123;?>    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

    upstream site{         server 172.16.170.138;         server 172.16.170.139;     }     server {       listen    80;       server_name localhost;         #charset koi8-r;       #access_log /var/log/nginx/log/host.access.log main;         location / {         root  /usr/share/nginx/html;         index index.html index.htm;         proxy_pass http://site;       }     

9.域名修改  把上面site,localhost改为www.a.com

Lamp安装

1.安装apache

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

2.安装mariadb(MySQL)

   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     systemctl start mariadb.service #启动MariaDB     systemctl stop mariadb.service #停止MariaDB     systemctl restart mariadb.service #重启MariaDB     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

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

5.访问测试

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

在客户端浏览器输入服务器IP地址,可以看到如下图所示相关的配置信息!
