systemd管理shadowsocks-libev多端口自启动

以下在Debian8和CentOS7测试成功。仅路径有所不同。
安装参考shadowsocks-libev在github的说明。Debian用jessie-backports安装，CentOS用Fedora-Copr安装。


以下说明为Debian8上的操作。


cp /lib/systemd/system/shadowsocks-libev.service /lib/systemd/system/shadowsocks-libev1.service
nano /lib/systemd/system/shadowsocks-libev1.service
