centos7 yum安装配置Lnmp和负载配置

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
