Docker快速部署OpenVPN

[toc]

通过docker快速实现OpenVPN搭建

# 拉取镜像

docker pull kylemanna/openvpn:2.4

# 创建配置文件

docker run -v /opt/openvpn:/etc/openvpn --rm kylemanna/openvpn:2.4 ovpn_genconfig -u tcp://ip[:port]

ip:port 设置的地址为你连接VPN访问的ip和端口，一般为公网IP和端口,一般端口为1194

运行结果

[root@bigdata-101 ~]# docker run -v /opt/openvpn:/etc/openvpn --rm kylemanna/openvpn:2.4 ovpn_genconfig -u udp://x.x.x.x:port

# 导出证书

导出客户端认证文件到本地

jast 为客户端名称

docker run -v /opt/openvpn:/etc/openvpn --rm kylemanna/openvpn:2.4 ovpn_getclient jast > /opt/jast.ovpn

# 启动VPN

docker run --name ov --restart=always --privileged=true -v /opt/openvpn:/etc/openvpn -d -p 1194:1194/tcp --cap-add=NET_ADMIN kylemanna/openvpn:2.4

如果公网访问VPN，公网的IP地址和端口要映射到当前容器所在服务器的1194端口

# 配置哪些流量走VPN

修改客户端文件jast.ovpn，在配置文件中添加

# 表示不接受服务器对于修改路由表的推送，而可以按照我们之后指定的规则去修改
route-nopull
# 这个参数设置了路由的度量值（metric），用于确定路由的优先级。路由的度量值越小，优先级越高。在有多个路由规则匹配的情况下，系统会选择度量值最小的路由。
route-metric 150
# 远程主机（remote_host）的流量通过本地网关（net_gateway）发送
route remote_host 255.255.255.255 net_gateway
# 172.19.0.0/16网段的流量通过本地网关发送
route 172.19.0.0 255.255.0.0 net_gateway
# 192.168.1.0/16网段的流量通过VPN网关（vpn_gateway）发送

注释掉这一行

redirect-gateway def1作用是将默认网关重定向到 VPN 服务器上，所以要注释掉。
