欢迎大家来到仓酷云论坛!Centos7装置pptpvpn
1、反省体系内核是不是撑持MPPE
[quote]modprobeppp-compress-18&&echoOK [/quote]2、反省体系是不是开启TUN/TAP撑持
[quote]cat/dev/net/tun
cat:/dev/net/tun:文件形貌符处于毛病形态 假如这条指令显现了局为上面的文本,则标明经由过程
[/quote]3、反省PPP是不是撑持MPPE
[quote]strings/usr/sbin/pppd|grep-imppe|wc-l
43 假如以上下令输入为“0”则暗示不撑持;输入为“30”或更年夜的数字就暗示撑持.
[/quote]4、装置ppp和iptables#PPTP必要这两个软件包,一样平常centOS自带
5、装置PPTP
yuminstallepel-release
yuminstallpptpd 6、设置PPTP

centos7默许接纳firewalld静态防火墙,我仍是更习气利用iptables [quote]yuminstalliptables-services

[quote]iptables-tnat-L#完成后能够检察NAT表是不是已失效 这里要注重办事器的网口纷歧定是eth0,用netstat-i检察
[/quote][quote]serviceiptablessave#保留防火墙设置
servicerestart#重启防火墙 [/quote]关于开启了iptables过滤的主机,必要开放VPN办事的端口:1723和gre协定 利用一下下令增加

假如iptables划定规矩中有回绝的选项,必要注重承受的要在回绝的后面。
Centos7的iptables默许划定规矩中就有

复制代码 增加的划定规矩必定要在这条划定规矩的后面,以是用拔出的***增加划定规矩

8、设置PPTP开机启动
servicepptpdstart#启动pptpd
systemctlenabledpptpd#设置开机启动
pptpd办事利用的端口是1723,这个端口是体系流动分派的,能够经由过程检察该端口反省pptpd办事的运转情形。
下令:netstat-ntpl
[root@Centos7~]#netstat-ntpl
ActiveInternetconnections(onlyservers)
ProtoRecv-QSend-QLocalAddressForeignAddressStatePID/Programname
tcp00127.0.0.1:6310.0.0.0:*LISTEN1423/cupsd

tcp000.0.0.0:446660.0.0.0:*LISTEN1358/rpc.statd

tcp00:::66:::*LISTEN1579/sshd
tcp00:::33794:::*LISTEN1358/rpc.statd
tcp00:::111:::*LISTEN1310/rpcbind
至此,VPN办事器搭建完成.
