4.

yum install -y docker

5.附加一篇博客：https://blog.csdn.net/qq_42712518/article/details/108311680

vi /etc/docker/daemon.json

输入 "registry-mirrors": ["https://pee6w651.mirror.aliyuncs.com"]

6.

systemctl start docker

docker ps  docker ps -a

7.

docker pull postgres

docker pull sonarqube

mkdir sonarqube

cd  sonarqube   mkdir data logs extensions

9.建卷

$> docker volume create --name sonarqube_data

$> docker volume create --name sonarqube_logs

$> docker volume create --name sonarqube_extensions

10.运行postgres

docker run  -d  --name pg  -p 5432:5432  -e POSTGRES_USER=sonar  -e POSTGRES_PASSWORD=sonar  postgres

11.运行sonarqube

https://docs.sonarqube.org/latest/setup/install-server/

docker run --rm 

    -p 9000:9000 

    -v sonarqube_extensions:/opt/sonarqube/extensions 

    sonarqube:8.9.1-community

删除docker镜像  docker rmi 镜像

11.安全组阿里云

systemctl status firewalld 

Jenkins

docker run -d -v jenkins_home:/var/jenkins_home -p 8080:8080 -p 50000:50000 jenkins/jenkins

docker exec -it 53d6d47b245b  /bin/bash

cat  /var/jenkins_home/secrets/initialAdminPassword

docker exec -it (这个是docker ps -a后names那列你想要进入的name) /bin/bash
cd /var/jenkins_home/workspace
ls
看见了

使用pm2

ps aux | grep node 查看正在运行的node项目
lsof -i tcp:8080 
kill -9 pid
scp build root@101.201.67.210:/build
