经常要在外网之间折腾的朋友,势必会想尽办法利用各种翻墙工具(如google自带的翻墙、psiphon、lantern、shadowsocksX....)。
其实这些工具本人都一一用过,感觉就是各种不稳定,而起速度还很慢。shadowsocksX相对还算好些,毕竟是要花钱买的,但也是遭到国内封杀,有时也连不上。考虑到经常需要,所以我就在亚太新加坡节点弄了一台做VPN代理服务器。用来翻墙。速度和稳定程度都还不错。
以前搭建VPN都要手工配置各种文件,相当麻烦。现在我推荐一个脚本给大家,vpn_centos.sh,一键搭建,省去之前的各种配置,而且还相当稳定。
兼容CentOS6、7,安装步骤如下:
wget http://mirrors.linuxeye.com/scripts/vpn_centos.sh chmod +x ./vpn_centos.sh ./vpn_centos.sh
脚本代码如下:
