1、验证内核是否加载了MPPE模块：
modprobe ppp-compress-18 && echo MPPE is ok
2、安装所需的软件包：
yum -y install ppp
wget ftp://rpmfind.net/linux/epel/7/x86_64/p/pptpd-1.4.0-2.el7.x86_64.rpm
rpm -ivh pptpd-1.4.0-2.el7.x86_64.rpm
3、配置PPP和PPTP的配置文件：
grep ^[^#] /etc/ppp/options.pptpd
vi /etc/ppp/options.pptpd
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 | name pptpd #refuse-pap #refuse-chap #refuse-mschap require-mschap-v2 require-mppe-128 ms-dns 8.8.8.8 ms-dns 8.8.4.4 proxyarp lock nobsdcomp novj novjccomp nologfd |
vi /etc/ppp/chap-secrets
| 1 | username pptpd passwd * |
vi /etc/pptpd.conf
| 1 2 3 4 | option /etc/ppp/options.pptpd logwtmp localip 192.168.0.1 remoteip 192.168.0.207-217 |
4、打开内核的IP转发功能：
vi /etc/sysctl.conf
| 1 | net.ipv4.ip_forward = 1 |
/sbin/sysctl -p
5、配置防火墙和NAT转发
| 1 2 3 4 5 | yum install iptables-services systemctl stop firewalld.service systemctl disable firewalld.service systemctl enable iptables.service systemctl start iptables.service |
开启包转发：
| 1 2 3 | iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -o eno16777736 -j MASQUERADE service iptables save service iptables restart |
开放端口和gre协议：
| 1 2 3 | iptables -A INPUT -p tcp -m state --state NEW,RELATED,ESTABLISHED -m tcp --dport 1723 -j ACCEPT iptables -A INPUT -p gre -m state --state NEW,RELATED,ESTABLISHED -j ACCEPT iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -o eno16777736 -j MASQUERADE |
添加规则：
| 1 2 3 4 5 6 7 | iptables -A INPUT -p gre -j ACCEPT iptables -A INPUT -p tcp -m tcp --dport 1723 -j ACCEPT iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT iptables -A FORWARD -s 192.168.0.0/24 -o eno16777736 -j ACCEPT iptables -A FORWARD -d 192.168.0.0/24 -i eno16777736 -j ACCEPT iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -o eno16777736 -j MASQUERADE service iptables save |
启动和查看服务：
| 1 2 3 | systemctl start pptpd systemctl enable pptpd systemctl status pptpd |
6.查看pptpd服务进程和端口：
| 1 2 3 4 5 | #ps -ef | grep pptpd root 25100 1 0 14:19 ? 00:00:00 /usr/sbin/pptpd -f root 25463 24275 0 14:52 pts/0 00:00:00 grep --color=auto pptpd # netstat -nutap | grep pptpd tcp 0 0 0.0.0.0:1723 0.0.0.0:* LISTEN 25100/pptpd |
以上就是小编为大家带来的linux中配置pptp服务器配置的方法全部内容了。
