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 | |

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 |
