首先创建个文件
vi /etc/yum.repos.d/nginx.repo
复制下面文本，保存并退出
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=0
enabled=1
运行以下命令进行安装
#yum install pcre 安装依赖包
#yum install nginx
后面整理了一些如/Ubuntu/Debian系统的安装包了
Red Hat/CentOS packages
Official Red Hat/CentOS packages To add nginx yum repository, create a file named /etc/yum.repos.d/nginx.repo and paste one of the configurations below:
CentOS:
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=0
enabled=1
RHEL:
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/rhel/$releasever/$basearch/
gpgcheck=0
enabled=1
Due to differences between how CentOS, RHEL, and Scientific Linux populate the $releasever variable, it is necessary to manually replace $releasever with either "5" (for 5.x) or "6" (for 6.x), depending upon your OS version.
Official Debian/Ubuntu packages Append the appropriate stanza to /etc/apt/sources.list. The Pgp page explains the signing of the nginx.org released packaging.
Ubuntu 10.04:
deb http://nginx.org/packages/ubuntu/ lucid nginx
deb-src http://nginx.org/packages/ubuntu/ lucid nginx
Debian 6:
deb http://nginx.org/packages/debian/ squeeze nginx
deb-src http://nginx.org/packages/debian/ squeeze nginx
Ubuntu PPA
This PPA is maintained by volunteers and is not distributed by nginx.org. It has some additional compiled-in modules and may be more fitting for your environment.
You can get the latest stable version of Nginx from the Nginx PPA on Launchpad: You will need to have root privileges to perform the following commands.
For Ubuntu 10.04 and newer:
sudo -s
nginx=stable # use nginx=development for latest development version
add-apt-repository ppa:nginx/$nginx
apt-get update
apt-get install nginxIf you get an error about add-apt-repository not existing, you will want to install python-software-properties. For other Debian/Ubuntu based distributions, you can try the lucid variant of the PPA which is the most likely to work on older package sets.
sudo -s
nginx=stable # use nginx=development for latest development version
echo "deb http://ppa.launchpad.net/nginx/$nginx/ubuntu lucid main" > /etc/apt/sources.list.d/nginx-$nginx-lucid.list
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys C300EE8C
apt-get update
apt-get install nginx
