1、配置防火墙

firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="10.255.200.1/30" port protocol="tcp" port="22222" accept"
firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="10.255.200.1/30" port protocol="tcp" port="5000" accept"
firewall-cmd --reload

2、安装SSH代理koko模块

# 下载koko安装包并解压
cd /sas/jumpserver
wget https://github.com/jumpserver/koko/releases/download/v2.3.1/koko-v2.3.1-linux-amd64.tar.gz
tar -xf koko-v2.3.1-linux-amd64.tar.gz
mv koko-v2.3.1-linux-amd64 koko

cd koko
#该执行文件放入/usr/local/bin/，实现非绝对路径调用 
mv kubectl /usr/local/bin/

#同样在koko目录下下载kubectl.tar.gz包
wget https://download.jumpserver.org/public/ kubectl.tar.gz 
tar -xf kubectl.tar.gz
chmod 755 kubectl
mv kubectl /usr/local/bin/rawkubectl
rm -rf kubectl.tar.gz

3、修改koko配置文件

# 备份原始配置文件
cd /sas/jumpserver/koko
cp config_example.yml config.yml

# 修改koko配置文件，以下仅列出需修改的项目
vi config.yml

# Jumpserver项目的url, api请求注册会使用
CORE_HOST: https://10.255.200.5
# 修改BOOTSTRAP_TOKEN保持与jumpserver/config.yml中的一致
BOOTSTRAP_TOKEN：xxxxxxxxxxxxxxxx
# 修改日志级别
LOG_LEVEL: ERROR
# 会话共享使用的类型修改为redis
SHARE_ROOM_TYPE: redis
# 修改Redis配置，注意IP为浮动IP
REDIS_HOST: 10.255.200.4
REDIS_PORT: 6379
REDIS_PASSWORD: xxxxxxxx
REDIS_DB_ROOM: 6

4、编写systemd系统服务管理脚本

# 编写SSH代理模块koko启动脚本
vi /sas/jumpserver/tools/koko.service.sh

#!/bin/bash

cd /sas/jumpserver/koko/

case $1 in
start)
    ./koko -d
    ;;
stop)
    ./koko -s stop
    ;;
restart)
    ./koko -s stop && ./koko -d
    ;;
*)
    ;;
esac

# 编写SSH代理模块系统服务配置
vi /usr/lib/system/system/koko.service

[Unit]
Description=Jumpserver Koko Services
After=network.target remote-fs.target redis.service keepalived.service jumpserver.service

[Service]
Type=forking
ExecStart=/usr/bin/bash /sas/jumpserver/tools/koko.service.sh start
ExecReload=/usr/bin/bash /sas/jumpserver/tools/koko.service.sh restart
ExecStop=/usr/bin/bash /sas/jumpserver/tools/koko.service.sh stop
Restart=on-failure
RestartSec=5

[Install]
WantedBy=multi-user.target

5、https证书验证错误处理

tengine启用https后需在所有部署koko和guacamole的主机上导入安全证书，否则koko访问api接口时会报错，处理的方法是将相关的证书信息加入主机的证书信任列表中。

# 查看目标API服务的证书信息，此方法对其它https服务一样适用
openssl s_client -showcerts -connect 10.255.200.5:443

6、其它

己注册过的koko实例因修改配置等原因需重新注册时，需要删除相关的accesskey

rm –rf /sas/jumpserver/koko/data/keys/.access_key

koko 日志文件路径：/sas/jumpserver/koko/data/logs

cat /sas/jumpserver/koko/data/logs/koko.log
