cd openvpn-version
配置openvpn
./configure
配置过程中可能出现的问题
执行过程中可能出现一些报错，观察最后给的报错信息，可根据报错提示进行处理，我遇到大部分都是缺少依赖包
每次处理完一个error之后，然后重新执行./configure文件，如果出现报错类似处理即可，直到。./configure执行成功
缺少libnl-genl-3-dev和pkg-config

checking whether TUNSETPERSIST is declared... yes
checking for setcon in -lselinux... no

checking for LIBNL_GENL... no
configure: error: libnl-genl-3.0 package not found or too old. Is the development package and pkg-config installed? Must be version 3.4.0 or newer for DCO
此时就是因为缺少依赖，所以需要手动安装
# 先查找，名称不一定一致
sudo apt search libnl-genl-3
输入结果如下：

此外还要注意报错信息的其他描述
这里的话就要安装pkg-config 库了，同上面类似，先查看相关库，再通过库名进行安装
sudo apt search pkg-config
sudo apt install libpkgconf-dev
OpenSSL不是最新库
此时选择安装最新的libssl-dev库就可以了
sudo apt install libssl-dev
缺少合适的LZ4压缩库
出现这种错误，即便安装lz4也无法解决，可能没有找到匹配的lz4库，不过我们可以禁掉这个配置选项
./configure --disable-lz4
lzo启用但是没找到
安装库liblzo2-dev
sudo apt install liblzo2-dev
libpam 启用但是没找到
安装库libpam0g-dev
sudo apt install libpam0g-dev
注意 如果没有找到类似的库，那么升级并更新一下apt包管理
到这里基本所有的checking过程中的error就成功解决了
缺少make构建工具
但是有些机器在执行./configure后 creating部分依然会出现报错
安装cmake
sudo apt install cmake
然后再重新执行./configure --disable-lz4即可
编译
make
安装
make install
至此，整个openvpn部署就算完成了，至于要以服务端启动，还是作为一个客户端启动，可以根据实际需要选择
部署服务端
部署客户端
进入到示例文件里面，找到启动服务端和客户端的脚本文件
cd /openvpn-version/sample/sample-config-files/
目录结构：
执行下面的命令进行启动：
注意 client.conf文件需要更改成自动的配置，安装之后的默认client.conf并不能用，是无法启动的
openvpn-startup.sh client.conf
