installNginx

赋予installNginx.ssh文件可执行限权

# chmod +x installNginx.ssh

执行安装

./installNginx.ssh

基本命令

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

虚拟主机管理

在安装目录（//usr/local/nginx/）里的site目录中有一个default.conf默认虚拟主机管理模版，后续拓展虚拟主机可以直接复制default.conf文件，文件名格式为 *.conf，只要后缀为.conf就能解析
