Nginx安装（CentOS）

发表于 作者 chpdirector

简介：

在CentOS上安装Nginx

安装环境及版本：

系统环境：CentOS Linux release 7.5.1804 (Core)
Nginx版本：使用yum安装

一、预备

如果安装Nginx的话，httpd就没有必要存在，查询是有已经安装了httpd，如果没有就跳过，如果有，则需要删除

查询命令：rpm -qa | grep httpd
删除命令：yum remove httpd*

[root@localhost python3Dir]# rpm -qa | grep httpd
httpd-tools-2.4.6-93.el7.centos.x86_64
httpd-2.4.6-93.el7.centos.x86_64
[root@localhost ~]# yum remove httpd*
