Posted 2020-06-14

    nginx是一款轻量级但高性能的Web服务器及反向代理服务器，也是邮件的代理服务器，越来越多的人开始使用Nginx来替代原本使用的Apache。

Nginx的安装：

1、CentOS&Redhat的yum安装（以CentOS6.x为例）：

        确认系统信息

[[email protected] ~]# cat /etc/redhat-release
CentOS release 6.7 (Final)
[[email protected] ~]# uname -r
2.6.32-504.el6.x86_64
[[email protected] ~]# uname -m
x86_64

        确认是否已经安装

[[email protected] ~]# rpm -aq nginx
[[email protected] ~]#

        首先建议将yum源修改为阿里云

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

        使用yum搜索nginx包

[[email protected] ~]# yum search nginx

        yum安装nginx

[[email protected] ~]# yum install nginx -y

        启动nginx

[[email protected] ~]# /etc/init.d/nginx start
Starting nginx:                                            [  OK  ]

        设置开机自启动nginx

[[email protected] ~]# chkconfig --list nginx
nginx          0:off1:off2:off3:off4:off5:off6:off
[[email protected] ~]# chkconfig nginx on
[[email protected] ~]# chkconfig --list nginx
nginx          0:off1:off2:on3:on4:on5:on6:off

2、Ubuntu&Debian的apt安装（以Debian7.x为例）：

        确认系统信息

[email protected]:~# cat /etc/issue
Debian GNU/Linux 7 \n \l
[email protected]:~#
[email protected]:~# uname -r
3.2.0-4-amd64
[email protected]:~# uname -m
x86_64

        确认是否已经安装

[email protected]:~# dpkg -s nginx
dpkg-query: package ‘nginx‘ is not installed and no information is available
Use dpkg --info (= dpkg-deb --info) to examine archive files,
and dpkg --contents (= dpkg-deb --contents) to list their contents.

        使用apt搜索nginx包
