installNginx

賦予installNginx.ssh文件可執行限權

# chmod +x installNginx.ssh

執行安裝

./installNginx.ssh

基本命令

service nginx [start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest]

虛擬主機管理

在安裝目錄（//usr/local/nginx/）裏的site目錄中有一個default.conf默認虛擬主機管理模版，後續拓展虛擬主機可以直接複製default.conf文件，文件名格式爲 *.conf，只要後綴爲.conf就能解析
