这篇文章主要为大家介绍了基于web管理OpenVPN服务的安装使用详解，有需要的朋友可以借鉴参考下，希望能够有所帮助，祝大家多多进步，早日升职加薪

正文

服务名称	版本	备注
OpenVPN	openvpn-2.4.12-1.el7.x86_64	github有开源一键安装脚本项目
操作系统	CentOS Linux 7 (Core)/Linux 3.10.0-1160.11.1.el7.x86_64
默认python	Python 2.7.5
Openvpnas	openvpn-as-2.11.0_794ab41d-CentOS7.x86_64.rpm
openvpn-as-bundled-clients	openvpn-as-bundled-clients-25.rpm

python版本修改

系统默认的python版本为2.7.5,此版本对目前的openvpnas依赖的运行时版本来说太低了，因此稍微调整下版本

rm -rf /usr/bin/python
ln -s /usr/bin/python3.6 /usr/bin/python

安装openVPN服务

GitHub上已经有人将安装的过程写成shell脚本了，我们这里只要去下载然后一键安装就好了。

安装并生成wahaha用户的客户端配置

wget -O openvpn-install.sh https://ghproxy.com/https://github.com/Nyr/openvpn-install/blob/master/openvpn-install.sh
bash ./openvpn-install.sh #按照提示完成安装即可
# 创建用户测试openVPN服务是否正常可用
[root@vm-24-13-centos openvpnas]# bash ./openvpn-install.sh

安装openvpn web 服务

在验证openVPN没有问题后，即可安装openvpnas服务，但是默认情况下，此web服务只允许两个客户端链接，因此我们需要参考网上的破解的方式，修改一下此限制。下面先安装一下web服务。

安装openvpnas

wget https://openvpn.net/downloads/openvpn-as-latest-CentOS7.x86_64.rpm # openvpn-as-2.11.0_794ab41d-CentOS7.x86_64.rpm

yum localinstall -y ./openvpn-as*.rpm

修改用户限制

网络上有存在不同版本的编译文件，不想使用的可以直接去找，我们这里使用的是最新的openvpnas服务，需要自己手动修改下

备份安装目录下的pyovpn-2.0-py3.6.egg文件

[root@vm-24-13-centos openvpnas]# cd /usr/local/openvpn_as/lib/python/
[root@vm-24-13-centos python]# cp pyovpn-2.0-py3.6.egg{,.back}
[root@vm-24-13-centos python]# ls -alh|grep pyovpn
drwxr-xr-x 37 root root 4.0K Oct  8 18:08 pyovpn
-rw-r--r--  1 root root 5.8M Oct  8 18:45 pyovpn-2.0-py3.6.egg
-rw-r--r--  1 root root 5.7M Oct  8 17:28 pyovpn-2.0-py3.6.egg.back #这是备份出来的文件
-rwxr-xr-x  1 root root  19K Jun 15 22:28 pyovpnc.cpython-36m-x86_64-linux-gnu.so

编译补丁文件

[root@vm-24-13-centos openvpnas]# cd /root/openvpnas
[root@vm-24-13-centos openvpnas]# mkdir compile &amp;&amp; cd $_
[root@vm-24-13-centos compile]# cp /usr/local/openvpn_as/lib/python/pyovpn-2.0-py3.6.egg .
[root@vm-24-13-centos compile]# unzip -q ./pyovpn-2.0-py3.6.egg
[root@vm-24-13-centos compile]# ls
common  EGG-INFO  pyovpn  pyovpn-2.0-py3.6.egg
[root@vm-24-13-centos compile]# cd pyovpn/lic/

[root@vm-24-13-centos lic]# vim uprop.py
[root@vm-24-13-centos lic]# cat uprop.py
from pyovpn.lic import uprop2
old_figure = None
def new_figure(self, licdict):
      ret = old_figure(self, licdict)
      ret['concurrent_connections'] = 6666
      return ret
#微信订阅号：云原生生态圈
for x in dir(uprop2):
      if x[:2] == '__':
         continue
      if x == 'UsageProperties':
         exec('old_figure = uprop2.UsageProperties.figure')
         exec('uprop2.UsageProperties.figure = new_figure')
      exec('%s = uprop2.%s' % (x, x))
[root@vm-24-13-centos lic]# python -O -m compileall uprop.py &amp;&amp; mv __pycache__/uprop.*.pyc uprop.pyc
Compiling 'uprop.py'...
# 最后打包一下就结束了
[root@vm-24-13-centos lic]# cd ../../
[root@vm-24-13-centos compile]# zip -rq pyovpn-2.0-py3.6.egg ./pyovpn ./EGG-INFO ./common

替换补丁文件，重启服务

cp ./pyovpn-2.0-py3.6.egg /usr/local/openvpn_as/lib/python/
systemctl restart openvpnas.service

使用openvpn账号登录

新版本会在openvpnas安装的时候初始化openvpn的密码

grep -i 'password.$' /usr/local/openvpn_as/init.log

配置客户端

在完成以上操作且验证没问题之后，就可以创建部分用户，来体验一下

从以上来看，不同的客户端用户可以分配不同的权限，以及客户端账号的认证方式等等，创建完成之后，使用客户端用户的账号以及密码登录openvpnas,下载客户端连接工具以及自助生成客户端的配置文件：访问地址为:https://ip:943/

登录之后，即可下载客户端软件以及创建对应的配置文件了

创建完成之后，在管理后台也可以管理用户的配置文件

下载配置文件后，即可在推荐的openvpn-connect或者Tunnelblick上打开使用了。

使用OpenVPN AS.不仅仅可以在web浏览器上更方便管理用户和权限，也能更方便的吊销证书等，同时也更大的化的方便客户端人员的使用。

到此，OpenVPNAS的主要介绍的就这些了，更多关于web管理OpenVPN服务安装的资料请关注脚本之家其它相关文章！
