good, 你已经有了一个自己的shadowsocks代理了，现在想要把这个代理公布出去给所有人分享。
但是没有两个小时，代理就没法使用了，为什么？因为你需要额外注意以下事项（以下步骤需要比较高的linux技能）
本文只关注于确保shadowsocks服务还“活着”，如果你希望让其跑得更快，请参考 
https://github.com/clowwindy/shadowsocks/wiki/Optimizing-Shadowsocks

1、 shadowsocks的timeout设置
超时时间越长，连接被保持得也就越长，导致并发的tcp的连接数也就越多。对于公共代理，这个值应该调整得小一些。推荐60秒。

2、 检查操作系统的各种限制
对于openvz的vps，特别需要检查一下

$ vi /etc/sysctl.conf
# 系统所有进程一共可以打开的文件数量， 每个套接字也占用一个文件描述字
fs.file-max = 1491124
# 系统同时保持TIME_WAIT套接字的最大数目，http 短链接会产生很多 TIME_WAIT 套接字。
net.ipv4.tcp_max_tw_buckets = 7000
# 关闭 tcp 来源跟踪
net.ipv4.conf.default.accept_source_route = 0
# 缩短套接字处于 TIME_WAIT 的时间， 60s -> 30s
net.ipv4.tcp_fin_timeout = 30
# 启用 TIME_WAIT 复用，使得结束 TIEM_WAIT 状态的套接字的端口可以立刻被其他套接字使用。
