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 

• 1
• 2
• 3
• 4
• 5

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！
