APPNAME=$1
VERSION=$2
PORT=$3
start(){
port_result=`netstat -anlpt | grep "${PORT}" || echo false`
if [[ $port_result == "false" ]];then
nohup java -jar -Dserver.port=${PORT} ${APPNAME}-${VERSION}.jar >${APPNAME}.log.txt 2>&1 &
else
stop
sleep 5
nohup java -jar -Dserver.port=${PORT} ${APPNAME}-${VERSION}.jar >${APPNAME}.log.txt 2>&1 &
fi
}

kill -15 $pid

(4)Jenkins给后端项目CD流水线添加参数
(5)Jenkins安装插件HTTP Request
(5) 修改流水线代码

(6)手动构建流水线
(7)watch命令观察
bash
# watch -n 1 "ps aux | grep 9099"
(8) 成功
(9) GitLab后端项目新建分支
(10)Jenkins后端项目CI流水线手动构建
(11) 成功
(12)Nexus查看
(13)Jenkins手动构建后端项目CD流水线
(14)成功
(15)查看本地目录
bash
# cd /optdevops03-devops-service/
# ls
2.Jenkins使用基于SaltStack的CD流水线部署前端应用
(1)主机安装nginx
bash
1)添加 nginx 到 yum 源中
sudo rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
2)安装 nginx (在把nginx添加到 yum 源之后,就可以使用 yum 安装了)
sudo yum install -y nginx
3)稍等一会,即可安装完成
4)启动 nginx
sudo systemctl start nginx.service
5)设置 nginx 开机自启动
sudo systemctl enable nginx.service
(2)nginx 配置信息
bash
1)网站文件存放默认位置(Welcome to nginx 页面)
/usr/share/nginx/html
2)网站默认站点配置
/etc/nginx/conf.d/default.conf
3)自定义 nginx 站点配置文件存放目录
/etc/nginx/conf.d/
4)nginx 全局配置文件
/etc/nginx/nginx.conf
5)启动 nginx
service nginx start
6)关闭 nginx
service nginx stop
7)重启 nginx
service nginx restart
service nginx reload
8) 加成nginx
nginx -t
(3)Jenkins新建前端项目CD流水线
(4)添加参数
(5)修改nginx配置文件
bash
# /etc/nginx/nginx.conf
bash

bash
# nginx -t
