Nginx的安裝

1、 What's Nginx?

Nginx [engine x] is an HTTP and reverse proxy server, a mail proxy server, and a generic TCP/UDP proxy server.

2、How to install?

準備工做：

1. 系統：ubuntu16.04 server
2. 網絡：暢通
3. 方式：經過deb包安裝
4. 其餘Linux平臺安裝方式參考：install nginx

安裝過程（本教程是root用戶執行命令，其餘用戶需在各個命令前加 sudo）

1. wget -c https://nginx.org/keys/nginx_signing.key
2. sudo apt-key add nginx_signing.key
3. echo 'deb http://nginx.org/packages/ubuntu/ xenial nginx' >> /etc/apt/sources.list
4. echo 'deb-src http://nginx.org/packages/ubuntu/ xenial nginx' >> /etc/apt/sources.list
5. apt update
6. apt install nginx
7. nginx # 啓動nginx

3、How to use Nginx？

• nginx -s signal

Where signal may be one of the following:

• stop — fast shutdown
• quit — graceful shutdown
• reload — reloading the configuration file
• reopen — reopening the log files

For Example:

1. nginx -s quit
2. nginx -s reload
3. nginx -s restart

if the master process ID is 1628, to send the QUIT signal resulting in nginx’s graceful shutdown, execute:

kill -s QUIT 1628

For getting the list of all running nginx processes, the ps utility may be used, for example, in the following way:

ps -ax | grep nginx
