pid=`cat /usr/local/nginx/logs/nginx.pid`

echo "nginx 已经启动，进程号为${pid}"

bin="${installDir}/sbin"

#将命令所在目录添加到系统参数PATH中，方便调用
addToPATH ${bin}


#设置开机启动
addNginxService
}

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
