Unbuntu修改Jenkins默认端口

Jenkins默认占用了8080端口，需要改成自定义端口。

第一步

vim /etc/init.d/jenkins

找到

check_tcp_port "http" "${HTTP_PORT}" "8080" "${HTTP_HOST}" "0.0.0.0" || return 2

把8080改为8088

第二步

vim /etc/default/jenkins

找到：

# port for HTTP connector (default 8080; disable with -1)
HTTP_PORT=8080

同样也把8080改为8088

第三步（可选）

vim /etc/nginx/conf.d/jenkins.conf

由于使用了nginx作为反向代理，所以Nginx也需要做相应修改：

location / {
    proxy_set_header X-Rea $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_set_header X-Nginx-Proxy true;
    proxy_pass http://localhost:8080;
    proxy_set_header X-Forwarded-Proto $scheme;
}

同样也把8080改为8088

第四步

vim /usr/lib/systemd/system/jenkins.service

找到

# Port to listen on for HTTP requests. Set to -1 to disable.
# To be able to listen on privileged ports (port numbers less than 1024),
# add the CAP_NET_BIND_SERVICE capability to the AmbientCapabilities
# directive below.
Environment="JENKINS_PORT=8080"

同样也把8080改为8088

第五步

重启Jenkins

systemctl restart jenkins

重启Nginx

systemctl restart nginx

Done~
