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
# sh service.sh devops03-devops-service 1.1.1 9099 start
APPNAME=$1
VERSION=$2
PORT=$3start(){port_result=`netstat -anlpt | grep "${PORT}" || echo false`if [[ $port_result == "false" ]];thennohup java -jar -Dserver.port=${PORT} ${APPNAME}-${VERSION}.jar >${APPNAME}.log.txt 2>&1 &elsestopsleep 5nohup java -jar -Dserver.port=${PORT} ${APPNAME}-${VERSION}.jar >${APPNAME}.log.txt 2>&1 &fi

}case $4 instart)startsleep 5check;;stop)stopsleep 5check;;restart)stopsleep 5startsleep 5check;;check)check;;*)echo "sh service.sh {start|stop|restart|check}";;
esac
(4)Jenkins给后端项目CD流水线添加参数
（5）Jenkins安装插件HTTP Request
(5) 修改流水线代码
pipeline {agent { label "build" }stages{stage("PullArtifacts"){steps{script{repoName = "${JOB_NAME}".split("/")[0]env.projectName ="${JOB_NAME}".split("/")[-1].split("_")[0]if ("${env.projectType}" == "maven"){type="jar"}if ("${env.projectType}" == "npm"){type="tar.gz"}PullArtifacts("${env.releaseVersion}","${env.projectName}",repoName,type)env.pkgName="${env.projectName}-${env.releaseVersion}.${type}"}}}stage("DeployHost"){steps{script{print("DeployHost")// 文件内容写到本地response = GetRepoFile(21, "service.sh", "master")writeFile file: 'service.sh', text: "${response}"sh "ls -a "if ("${env.deployTool}" == "saltstack"){targetHosts = "${env.saltHosts}"println(targetHosts)localDeployDir = "/srv/salt/${env.projectName}"sh """[ -d ${localDeployDir} ] || mkdir -p ${localDeployDir}mv service.sh ${env.pkgName} ${localDeployDir}# 清理发布目录salt -L "${targetHosts}" cmd.run "rm -fr ${targetDir}/${env.projectName}/* && mkdir -p ${targetDir}/${env.projectName} || echo file is exists"# 发布应用salt -L "${targetHosts}" cp.get_file salt://${env.projectName}/${env.pkgName} ${targetDir}/${env.projectName}# 发布启动脚本salt -L "${targetHosts}" cp.get_file salt://${env.projectName}/service.sh ${targetDir}/${env.projectName}# 启动服务salt -L "${targetHosts}" cmd.run "cd ${targetDir}/${env.projectName} ;source /etc/profile && sh service.sh ${env.projectName} ${env.releaseVersion} ${env.port} start"# 检查服务sleep 5salt -L "${targetHosts}" cmd.run "cd ${targetDir}/${env.projectName} ;source /etc/profile && sh service.sh ${env.projectName} ${env.releaseVersion} ${env.port} check""""}}}}stage("ServiceCtrl"){steps{script{print("ServiceCtrl")}}}stage("HealthCheck"){steps{script{print("HealthCheck")}}}}

}（6）手动构建流水线
（7）watch命令观察
# 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
# 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
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.rpm2)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 nginx3）稍等一会，即可安装完成4）启动 nginx
sudo systemctl start nginx.service5）设置 nginx 开机自启动
sudo systemctl enable nginx.service
（2）nginx 配置信息
1）网站文件存放默认位置（Welcome to nginx 页面）
/usr/share/nginx/html2）网站默认站点配置
/etc/nginx/conf.d/default.conf3）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.conf5）启动 nginx
service nginx start6）关闭 nginx
service nginx stop7）重启 nginx
service nginx restart
service nginx reload8) 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
# /etc/nginx/nginx.conf 1 2 user nginx;3 worker_processes auto;4 5 error_log /var/log/nginx/error.log notice;6 pid /var/run/nginx.pid;7 8 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 }
# nginx -t# curl 127.0.0.1:8099
