1. wget https://files.cnblogs.com/files/wangbin/vpn_centos.sh2. chmod +x ./vpn_centos.sh3. ./vpn_centos.sh

可在-u、-p后随意更改⾃⼰的登录⽤户名和密码。但密码长度必须⼤于8个 ASCII字符，否则为了安全，脚本将会随机⽣成密码。 注：

如果你⽆法访问⼀些特定⽹站，建议你修改ppp接⼝的MTU（很多时候能连接vpn但是⽆法打开某些⽹页也可能跟这个有关系）输⼊vi /etc/ppp/ip-up

在倒数第⼆⾏加⼊如下内容：/sbin/ifconfig $1 mtu 1400缺省 MTU:1496

保存后需要重启PPTP服务器，指令如下: systemctl restart pptpd
