1环境
表1 主机
管理端192.168.204.8gitlab被管理端192.168.204.180K8S master1被管理端192.168.204.181K8S node1被管理端192.168.204.182K8S node2
(2) 管理端安装ansible
#安装epel-release
yum install -y epel-release #安装ansible
yum install -y ansible#hosts文件位置:/etc/ansible/hosts
vim /etc/ansible/hosts# 主机hosts文件
vim /etc/hosts(3)ansible远程ping
# ansible all -m ping 2.K8S 节点安装nginx
1K8S查看节点状态
# kubectl get node2) 节点安装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
3nginx 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/4nginx 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
4修改nginx配置文件
# /etc/nginx/nginx.confuser nginx;
worker_processes auto;error_log /var/log/nginx/error.log notice;
pid /var/run/nginx.pid;events {worker_connections 1024;
}http {include /etc/nginx/mime.types;default_type application/octet-stream;log_format main $remote_addr - $remote_user [$time_local] $request $status $body_bytes_sent $http_referer $http_user_agent $http_x_forwarded_for;access_log /var/log/nginx/access.log main;sendfile on;tcp_nopush on;tcp_nodelay on;types_hash_max_size 2048;keepalive_timeout 65;#gzip on;include /etc/nginx/conf.d/*.conf;server {listen 8099;server_name _;root /usr/share/nginx/html/devops03-devops-ui;# Load configuration files for the default server block.include /etc/nginx/default.d/*.conf;location / {}error_page 404 /404.html;location /40x.html {}error_page 500 502 503 504 /50x.html;location /50x.html {}}}
master1节点 node1节点 node2节点 3.Jenkins使用GitLab共享库实现基于Ansible的CD流水线部署前后端应用
1修改GitLab共享库目录 (2) 修改部署类 Deploy.groovy
package org.devops//SaltStackdef DeployBySalt(){targetHosts ${env.saltHosts}localDeployDir /srv/salt/${env.projectName}sh [ -d ${localDeployDir} ] || mkdir -p ${localDeployDir}mv ${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}if (${env.projectType} npm) {sh # 解压salt -L ${targetHosts} cmd.run cd ${targetDir}/${env.projectName} ;tar zxf ${env.pkgName}}if (${env.projectType} maven) {// 文件内容写到本地gitlab new Gitlab()response gitlab.GetRepoFile(21, service.sh, master)writeFile file: service.sh, text: ${response}sh ls -a sh mv service.sh ${localDeployDir}# 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}
}//ansible
def DeployByAnsible(){//将主机写入清单文件sh rm -fr hostsfor (host in ${env.ansibleHosts}.split(,)){sh echo ${host} hosts}// sh cat hosts// ansible 发布sh # 主机连通性检测ansible ${env.ansibleHosts} -m ping -i hosts # 清理和创建发布目录ansible ${env.ansibleHosts} -m shell -a rm -fr ${env.targetDir}/${env.projectName}/* mkdir -p ${env.targetDir}/${env.projectName} || echo file is exists # 复制appansible ${env.ansibleHosts} -m copy -a src${env.pkgName} dest${env.targetDir}/${env.projectName}/${env.pkgName} if (${env.projectType} npm){sh ansible ${env.ansibleHosts} -m shell -a cd ${env.targetDir}/${env.projectName} ; tar zxf ${env.pkgName} -u root }if (${env.projectType} maven){// 文件内容写到本地gitlab new Gitlab()response gitlab.GetRepoFile(21,service.sh, master)writeFile file: service.sh, text: ${response}sh ls -a sh # 复制脚本ansible ${env.ansibleHosts} -m copy -a srcservice.sh dest${env.targetDir}/${env.projectName}/service.sh # 启动服务ansible ${env.ansibleHosts} -m shell -a cd ${env.targetDir}/${env.projectName} ;source /etc/profile sh service.sh ${env.projectName} ${env.releaseVersion} ${env.port} start -u root# 检查服务 sleep 10ansible ${env.ansibleHosts} -m shell -a cd ${env.targetDir}/${env.projectName} ;source /etc/profile sh service.sh ${env.projectName} ${env.releaseVersion} ${env.port} check -u root}
}(3) 修改流水线 cd.jenkinsfile
Library(mylibmaster) _
import org.devops.*def artifacts new Artifacts()
def gitlabutil new Gitlab()
def deployer new Deploy()pipeline {agent { label build }options {skipDefaultCheckout true}stages{stage(PullArtifacts){steps{script{repoName ${JOB_NAME}.split(/)[0]env.projectName ${JOB_NAME}.split(/)[-1].split(_)[0]if (${env.projectType} maven){typejar}if (${env.projectType} npm){typetar.gz}artifacts.PullArtifacts(${env.releaseVersion},${env.projectName},repoName,type)env.pkgName${env.projectName}-${env.releaseVersion}.${type}}}}stage(DeployHost){steps{script{print(DeployHost)if (${env.deployTool} saltstack){deployer.DeployBySalt() }if (${env.deployTool} ansible){deployer.DeployByAnsible() }}}}}
}(4) Jenkins修改前后端项目流水线参数 5手动构建前端流水线 6Blue Ocean查看
成功 7手动构建后端流水线 8Blue Ocean查看 二、问题
1.ansible安装报错
1报错 2原因分析
yum源
3解决方法
# vim /etc/resolv.conf
nameserver 8.8.8.8
nameserver 114.114.114.114成功 2.ansible远程ping失败
(1) 报错 2原因分析
从输出提示上基本可以了解到由于在本机的~/.ssh/known_hosts文件中并有fingerprint key串ssh第一次连接的时候一般会提示输入yes 进行确认为将key字符串加入到 ~/.ssh/known_hosts 文件中
3解决方法
第一种在本地先SSH登录一下对方设备下次ansible 就可以正常操作了但是比较麻烦
第二种设置参数为不检查key
vim /etc/ansible/ansible.cfghost_key_checking False #71行取消注释 如继续操作出现如下报错需要修改被管理端/etc/hosts
注释被管理端域名 如继续操作出现如下报错修改 /etc/ansible/hosts
修改后
192.168.204.180 ansible_port22 ansible_userroot ansible_password123123
192.168.204.181 ansible_port22 ansible_userroot ansible_password123123
192.168.204.182 ansible_port22 ansible_userroot ansible_password123123 成功 3. Jenkins流水线通过ansible命令直接ping多台机器的网络状态报错
(1) 报错 2原因分析
单向的ssh验证
3解决方法
ssh-keygen一路回车,主要是用来免密通信的
ssh-copy-id 被控端IP 需要输入对应主节的root密码
# ssh-copy-id root192.168.204.180# ssh-copy-id root192.168.204.181# ssh-copy-id root192.168.204.182 成功
