CentOS6下Nginx安装配置

lbdbzj110

　　本人虚拟机安装的CentOS6.9和CentOS7.4都是仅主机模式，为了尝试不同方式安装nginx，将CnetOS6.9的网络模式切换成桥接模式。
一：桥接模式下安装Nginx（CentOS6.9）
--查看系统是否有Nginx
[root@centos6 ~]# find -name nginx
--卸载原有的Nginx
[root@centos6 ~]# yum remove nginx
--建立yum库
vim /etc/yum.repos.d/nginx.repo

　　--安装yum库
yum repolist

　　--查看yum库
yum info nginx

　　--基于yum库安装Nginx
yum install nginx

　　看报错：原因是openssl版本太低，其实是nginx软件包的版本高了，系统是CentOS6，得将yum库里的nginx软件包版本更新为el6

　　--清除yum缓存信息
[root@centos6 ~]# yum clean all
--列出yum库中nginx软件包
[root@centos6 ~]# yum list | grep nginx

　　顺便更新下Openssl版本
--使用命令查看Openssl版本
rpm -qa |grep openssl
　　--更新下Openssl版本
yum update openssl
　　--再次安装Nginx
yum install nginx

　　--启动Nginx
