一、实验

1.Jenkins使用基于SaltStack的CD流水线部署后端应用

（1）GitLab添加Token

(2)Jenkins添加凭据

（3）devops03-env 添加脚本

bash 复制代码 
# sh service.sh devops03-devops-service 1.1.1 9099 start
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
}


stop(){
    pid=`netstat -anlpt | grep "${PORT}" | awk '{print $NF}' | awk -F '/' '{print $1}'`
    kill -15 $pid
}


check(){
    proc_result=`ps aux | grep java | grep "${APPNAME}" | grep -v grep || echo false`
    port_result=`netstat -anlpt | grep "${PORT}" || echo false`
    url_result=`curl -s http://localhost:${PORT} || echo false `

    if [[ $proc_result == "false" || $port_result == "false" || $url_result == "false" ]];then
        echo "error"
    else
        echo "ok"
    fi
}

case $4 in
    start)
        start
        sleep 5
        check
        ;;

    stop)
        stop
        sleep 5
        check
        ;;
    restart)
        stop
        sleep 5
        start
        sleep 5
        check
        ;;
    check)
        check
        ;;
    *)
        echo "sh service.sh {start|stop|restart|check}"
        ;;
esac

(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 复制代码 
# 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 复制代码 
# 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 复制代码 
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 复制代码 
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 复制代码 
# /etc/nginx/nginx.conf
bash 复制代码 
  1 
  2 user  nginx;
  3 worker_processes  auto;
  4 
  5 error_log  /var/log/nginx/error.log notice;
  6 pid        /var/run/nginx.pid;

  9 events {
 10     worker_connections  1024;
 11 }
 12 
 13 
 14 http {
 15     include       /etc/nginx/mime.types;
 16     default_type  application/octet-stream;
 17 
 18     log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
 19                       '$status $body_bytes_sent "$http_referer" '
 20                       '"$http_user_agent" "$http_x_forwarded_for"';
 21 
 22     access_log  /var/log/nginx/access.log  main;
 23 
 24     sendfile        on;
 25     tcp_nopush      on;
 26     tcp_nodelay     on;
 27     types_hash_max_size 2048;
 28 
 29 
 30     keepalive_timeout  65;
 31 
 32     #gzip  on;
 33 
 34     include /etc/nginx/conf.d/*.conf;
 35 
 36 
 37 server {
 38     listen 8099;
 39     server_name _;
 40     root /usr/share/nginx/html/devops03-devops-ui;
 41 
 42     # Load configuration files for the default server block.
 43     include /etc/nginx/default.d/*.conf;
 44 
 45     location / {
 46     }
 47 
 48     error_page 404 /404.html;
 49         location = /40x.html {
 50     }
 51 
 52     error_page 500 502 503 504 /50x.html;
 53         location = /50x.html {
 54     }
 55  }
bash 复制代码 
# nginx -t

# curl 127.0.0.1:8099
