Ubuntu14.04預設的安裝源中安裝的是Nginx 1.4.6
echo deb http://nginx.org/packages/ubuntu/ trusty nginx >> /etc/apt/sources.list.d/nginx.list
echo deb-src http://nginx.org/packages/ubuntu/ trusty nginx >> /etc/apt/sources.list.d/nginx.list
wget http://nginx.org/keys/nginx_signing.key && apt-key add nginx_signing.key
apt-get update
apt-cache policy nginx 檢視版本
apt-get install -y nginx=1.14.0-1~trusty
centos 7 版本升級nginx
1、首先下載對應最新版nginx
wget http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
2、然後就是建立yum倉庫
rpm -ivh nginx-release-centos-7-0.el7.ngx.noarch.rpm
3、解除安裝系統原有的舊版的nginx
yum remove nginx
4、下載安裝nginx
yum install nginx
- 升級也可以
（yum update nginx -y）
5、啟動nginx
systemctl start nginx
錯誤
nginx: [emerg] module "/usr/lib64/nginx/modules/ngx_http_geoip_module.so" version 1012002 instead of 1014000 in /usr/share/nginx/modules/mod-http-geoip.conf:1
解決方法
yum remove nginx-mod*
yum install nginx-module-*
