Centos 7 上部署 Ocserv Cisco AnyConnect 服务端

本文介绍了如何在 Centos 7 上部署 Ocserv 服务端，并使用锐速优化网速。

一直以来都在使用Shadowsocks，速度快、基本不受某墙干扰，电脑、安卓、ios都有客户端，路由器也能刷入实现家里多部终端使用。

但是最近入手了Blackberry Passport，不要问我什么还入这不跟不上时代的手机，其实原因仅仅是因为“喜欢”，哪怕应用少，摆在那里我也觉得是一件艺术品。试玩之后发现我所在的敏感地区不能正常使用黑莓的应用商店和BBM，在家里虽然可以通过路由器爬墙使用，但外出就有些不便，黑莓OS10上又无法使用Shadowsocks，所以在自己的VPS上折腾了下OpenConnect Server(ocserv)。

部署环境

• VPS ：hostwinds
• 部署环境：Centos 7.2
• Ocserv版本：0.10.8

安装须知

为了省事，这里选择Travis Lee提供的一键安装脚本，安装前先看看须知：

• 支持自动判断防火墙，请确保 Firewalld 或者 iptables 其中一个是 active 状态；
• 默认采用用户名密码验证，本安装脚本编译的 ocserv 也支持 pam 验证，只需要修改配置文件即可；
• 默认配置文件在 /usr/local/etc/ocserv/ 目录，可自行更改脚本里的参数；
• 安装时会提示你输入端口、用户名、密码等信息，也可直接回车采用默认值，密码是随机生成的；
• 安装脚本会关闭 SELINUX；
• 自带路由表，只有路由表里的 IP 才会走 VPN，如果你有需要添加的路由表可自行添加，最多支持 200 条；
• 如果你有证书机构颁发的证书，可以把证书放到脚本的同目录下，确保文件名和脚本里的匹配，安装脚本会使用你的证书，客户端连接时不会提示证书错误；
• 配置文件修改为每个账号允许 10 个连接，全局 1024 个连接，可修改脚本前面的变量。1024 个连接大约需要 2048 个 IP，所以虚拟接口的 IP 配置了 8 个 C 段。

安装 Ocserv

首先打开终端登陆，执行以下命令

wget https://raw.githubusercontent.com/travislee8964/Ocserv-install-script-for-CentOS-RHEL-7/master/ocserv-install-script-for-centos7.sh

编辑下载下来的脚本文件

vi ocserv-install-script-for-centos7.sh

将其中 ocserv_version=”0.10.9″ 这一行的版本号改成 0.10.8，据说此版本较稳定。

然后执行脚本

sh ocserv-install-script-for-centos7.sh

安装过程中会提示你输入端口、用户名和密码等，自己按需填写。

安装完成后编辑配置文件

vi /usr/local/etc/ocserv/ocserv.conf

因为锐速只能加速TCP协议，所以将udp端口这一行注释掉

#udp-port = 10443

配置文件中使用了路由表黑名单，如果使用白名单，将包含 route = 的条目全部注释掉，例如

#route = 10.10.10.0/255.255.255.0 #route = 192.168.0.0/255.255.0.0

然后使用no-route添加白名单

no-route = 1.0.0.0/255.192.0.0 no-route = 1.64.0.0/255.224.0.0 no-route = 1.112.0.0/255.248.0.0 no-route = 1.176.0.0/255.240.0.0 no-route = 1.192.0.0/255.240.0.0 no-route = 14.0.0.0/255.224.0.0

223.128.0.0/255.128.0.0

保存配置文件，执行下面的代码重启Ocserv服务

systemctl restart ocserv.service

到这里就完成了Ocserv 的服务端部署工作，到手机上安装 Cisco AnyConnect 客户端，连接时如果提示证书不安全，记得要点信任，输入用户名和密码就能畅游网络了。

如果想给朋友们使用，也可以添加几个用户，使用下面的命令

ocpasswd -c /usr/local/etc/ocserv/ocpasswd 用户名

执行后会提示设置密码，按需输入即可。

安装锐速

这里也使用一键安装脚本，执行

wget --no-check-certificate -qO /tmp/appex.sh "https://raw.githubusercontent.com/0oVicero0/serverSpeeder_Install/master/appex.sh" && bash /tmp/appex.sh 'install'

安装过程中可能会提示选择版本，按提示选择即可。

至此，Ocserv 和 锐速都安装完成，因为注释掉了UDP端口，所以当连接到服务端时都走的TCP端口，这样锐速就能提供加速了。
