之前用docker的这个：[https://github.com/wppurking/ocserv-docker][https_github.com_wppurking_ocserv-docker]

但是不能定制路由，还是自己安一个

1、安装epel的yum源，安装ocserv

yum install epel-release -y       
    yum install ocserv -y

2.修改配置文件

/etc/ocserv/ocserv.conf

内容如下

# 这里用密码验证
    auth = "plain[passwd=/etc/ocserv/ocpasswd]"
    
    # TCP and UDP port number
    tcp-port = 443
    udp-port = 443
    
    run-as-user = ocserv
    run-as-group = ocserv
    
    socket-file = ocserv.sock
    chroot-dir = /var/lib/ocserv
    isolate-workers = true
    
    max-clients = 1024
    max-same-clients = 2
    keepalive = 32400
    dpd = 90
    mobile-dpd = 1800
    switch-to-tcp-timeout = 25
    try-mtu-discovery = false
    
    # 证书路径 默认
    server-cert = /etc/pki/ocserv/public/server.crt
    server-key = /etc/pki/ocserv/private/server.key
    
    # ca证书
    ca-cert = /etc/pki/ocserv/cacerts/ca.crt
    cert-user-oid = 0.9.2342.19200300.100.1.1
    tls-priorities = "NORMAL:%SERVER_PRECEDENCE:%COMPAT:-VERS-SSL3.0"
    
    
    auth-timeout = 240
    min-reauth-time = 300
    max-ban-score = 50
    ban-reset-time = 300
    cookie-timeout = 300
    deny-roaming = false
    rekey-time = 172800
    rekey-method = ssl
    
    use-occtl = true
    pid-file = /var/run/ocserv.pid
    device = vpns
    predictable-ips = true
    default-domain = example.com
    ping-leases = false
    
    cisco-client-compat = true
    dtls-legacy = true
    user-profile = profile.xml
    
    # DNS地址
    dns = 10.24.11.254
    dns = 219.148.204.66
    dns = 219.149.6.99
    
    # IP地址和掩码
    ipv4-network = 192.168.249.0/24
    
    # 路由表
    route = 10.24.11.0/255.255.255.0
    route = 10.24.0.0/255.255.0.0
    route = 172.20.0.0/255.255.0.0
    route = 10.244.0.0/255.255.0.0
    route = 106.75.12.89/255.255.255.255
    route = 106.75.117.178/255.255.255.255

3、管理用户

配置文件/etc/ocserv/ocpasswd中可以看到创建的用户和加密后的密码。

创建命令

touch /etc/ocserv/ocpasswd

常用命令

#创建用户，需要输入密码
    ocpasswd -c /etc/ocserv/ocpasswd user1
    #禁用用户
    ocpasswd -c /etc/ocserv/ocpasswd -l user1
    #解锁被禁用的用户
    ocpasswd -c /etc/ocserv/ocpasswd -u user1
    #删除用户
    ocpasswd -c /etc/ocserv/ocpasswd -d user1

4.开防火墙

firewall-cmd --add-port=443/tcp --permanent
    firewall-cmd --add-port=443/udp --permanent
    # 允许防火墙伪装IP 必须设置
    firewall-cmd --add-masquerade --permanent
    firewall-cmd --reload

高于1024端口的建议禁用SELINUX

编辑 /etc/selinux/config

将SELINUX=enforcing改为SELINUX=disabled
    重启后生效

5、设置开机自启

#开机自启
    systemctl enable ocserv 
    #启动
    systemctl start ocserv
    #查看状态
    systemctl status ocserv

6.客户端连接

安装好anyconnect-win-4.5.05030-core-vpn-webdeploy-k9.exe输入服务端网址，连上服务器后输入账号和密码即可。
