简单记录在CentOS7下yum安装LNMP以及LAMP的过程。

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

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

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 ieccohomo.com;

#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://ieccohomo.com;

}

9.域名修改  把上面(ieccohomo.com)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

phpinfo();

?>

:wq! #保存退出

在客户端浏览器输入服务器IP地址端口号
