Shadowsocks-libev 多用户 多端口 多实例 自启动

shadowsocks-libev并不像go版本或python版本的shadowsocks客户端/服务端软件那样直接支持多实例配置（相关说明看这里）。shadowsocks-libev需要通过加载不同的配置文件来实现多端口使用。


在CentOS启动脚本shadowsocks-libev的基础上做修改，实现多个配置文件自动加载：

esac
exit $RETVAL


将上述脚本保存为/etc/init.d/shadowsocks-libev并添加执行权限，就可以用下面命令启动了：

/etc/init.d/shadowsocks-libev start

启动后，可以通过以下命令查看ss-server是否监听了两个配置文件的端口：

netstat -tlnp

另外，也可以通过修改以上启动脚本来实现更多配置文件的加载。
