一、下载openvpn

[root@localhost ~]# yum -y install epel-release
[root@localhost ~]# yum -y install openvpn

二、创建一个配置文件的路径

#路径需要手动创建
[root@localhost ~]# mkdir -p /etc/openvpn/client/config/

三、把其他客户端的配置文件复制过来

下面这个是我Windows上的openvpn的客户端配置文件，可以直接拷贝到linux上面去用，里面包含ca证书等配置

四、把此配置文件放到刚刚创建的路径下（不用做任何改动）

[root@localhost config]# ls
client10.ovpn
[root@localhost config]# pwd
/etc/openvpn/client/config

五、启动openvpn

[root@localhost config]# openvpn /etc/openvpn/client/config/client10.ovpn
