基础环境的配置

rm /etc/localtime #删除link
ln -vs /usr/share/zoneinfo/Asia/Shanghai /etc/localtime #软件link
yum install ntpdate -y
ntpdate time.nist.gov
 
systemctl  stop firewalld  &&  systemctl  disable firewalld
yum -y install iptables-services  &&  systemctl  start iptables  &&  systemctl  enable iptables&&  iptables -F  &&  service iptables save

swapoff -a && sed -i '/ swap / s/^\(.*\)$/#\1/g' /etc/fstab
setenforce 0 && sed -i 's/^SELINUX=.*/SELINUX=disabled/' /etc/selinux/config

 

1.拉取rancher镜像 docker基础环境不再部署

docker pull rancher/rancher
docker inspect rancher/rancher:latest

准备jenkins文件目录

mkdir -p /docker_volume/rancher_home/rancher
mkdir -p /docker_volume/rancher_home/auditlog

启动docker服务

docker run -d --restart=unless-stopped -p 80:80 -p 443:443 \
-v /docker_volume/rancher_home/rancher:/var/lib/rancher \
-v /docker_volume/rancher_home/auditlog:/var/log/auditlog \
--name rancher rancher/rancher  

如果需要可以放行端口

firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --zone=public --add-port=443/tcp --permanent
firewall-cmd --reload

rancher配置信息为

https://192.168.120.81/g/clusters
admin
deyi81!

 

可以在节点创建一些标签方便调度

创建标签
iprange=82
iprange=83
deploy=worker

docker部署jekins

 

1.拉取jekins镜像

docker pull jenkins/jenkins:alpine
docker inspect jenkins/jenkins:alpine

2.准备jenkins目录

mkdir -p /docker_volume/jenkins_home

3.部署jenkins项目-安装项目参数在rancher中配置

docker run -d --restart unless-stopped --name jenkins \
    -p 30000:8080 -p 30001:50000 \
    -v /docker_volume/jenkins_home:/var/jenkins_home \
    jenkins/jenkins:alpine

注意需要映射目录

jenkins-home
/docker_volume/jenkins_home
/var/jenkins_home
dockersock
/var/run/docker.sock
/var/run/docker.sock
docker
/usr/bin/docker
/usr/bin/docker
yilai #依赖 不然每次重启项目需要重新拉取依赖
/root/.m2/
/root/.m2/

高级中命令 因为需要root权限
uuid
0

安全/主机设置 #不然可能无法ping通外网
dns
8.8.8.8
223.5.5.5

/etc/hosts映射

151.101.52.215  repo.maven.apache.org

 

 

因为已经拉取过了选从不拉取

 

 

 读取密码文件

/var/jenkins_home/secrets/initialAdminPassword

因为docker做了映射所有主机查看密码的路径为
[root@rancher81 ~]# cat /docker_volume/jenkins_home/secrets/initialAdminPassword
10f222faf03a42998b05be748acebf80

jenkins密码设置

白屏无法访问注意

iptables -F 清除防火墙
systemctl restart docker 重启docker 服务
白屏跳过更改更新连接和ip映射

git命令无法使用

全局工具配置
Default
/usr/bin/git

seting文件位置
/docker_volume/jenkins_home/tools/hudson.tasks.Maven_MavenInstallation/jenkins-in-maven/conf/settings.xml
本地的三行应该不需要配置
<localRepository>

  <name>aliyun maven</name>

镜像仓库的部署和查看

拉取镜像

docker pull registry:latest

mkdir /docker_volume/registry -p
/var/lib/registry

 

 

查看镜像

curl http://192.168.130.81:5000/v2/_catalog
curl http://192.168.130.81:5000/v2/dygaeureka/tags/list #dygaeureka为项目名

vi /etc/docker/daemon.json

{ "registry-mirrors": ["https://rncxm540.mirror.aliyuncs.com"],
"insecure-registries": ["192.168.130.81:5000"]
 }

systemctl daemon-reload && systemctl restart docker

升级插件可以下载后上传上去    
Docker plugin
Docker API Plugin

 

插件目录可以把下载好的插件直接拷贝到插件目录然后重启jenkins
ls /docker_volume/jenkins_home/plugins/

dygapayment-app
192.168.130.81:5000/dygapayment-app:V3.6.1

 

htpa测试注意需要先设置预留内存和限制内存 例如nginx
