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 necodon.cc; 

    #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://necodon.cc;
    }

9.域名修改  把上面(necodon.cc)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！
