dockers安装校验:

docker version
docker run hello-world

docker 安装jenkins

详细步骤https://blog.csdn.net/weixin_46785144/article/details/118282023
docker安装jenkins无法安装插件https://blog.csdn.net/qq_37023928/article/details/95739285?spm=1001.2101.3001.6650.9&utm_medium=distribute.pc_relevant.none-task-blog-2%7Edefault%7EBlogCommendFromBaidu%7ERate-9.pc_relevant_aa&depth_1-utm_source=distribute.pc_relevant.none-task-blog-2%7Edefault%7EBlogCommendFromBaidu%7ERate-9.pc_relevant_aa&utm_relevant_index=15

docker run -d -p 10240:8080 -p 10241:50000 -v /usr/local/docker/jenkins_mount:/usr/local/docker/jenkins_mount/jenkins_home -v /etc/localtime:/etc/localtime --name myjenkins jenkins/jenkins

docker 安装MySQL:8.0.15
https://blog.csdn.net/demon119/article/details/107310170/

#查找mysql有哪些版本(其他类似)
docker search mysql
docker pull mysql:8.0.15
#docker启动mysql8.0.15
docker run -itd --name mysql-test -p 3308:3306 -e MYSQL_ROOT_PASSWORD=123456 mysql:8.0.15

docker中安装mysql后进入mysql命令行

docker ps 
#以下2步或者 docker exec -it 容器id mysql -u root -p
docker exec -it b30062adc08c(mysql容器id) /bin/bash
mysql -u root -p

docker启动mysql后本地连不上(mysql初始化后只能本机访问要改为%)
ALTER USER ‘root’@’%’ IDENTIFIED WITH mysql_native_password BY ‘123456’;
flush privileges;

docker安装redis

docker run -p 6379:6379 --name myredis -v /usr/local/docker/redis/redis.conf:/etc/redis/redis.conf -v /usr/local/docker/redis/data:/data -d redis redis-server /etc/redis/redis.conf --appendonly yes

dockers配置nacos

https://www.jianshu.com/p/43d2dc65d7c6
要先搭建mysql在mysql中插入nacos库(docker安全控制限制了mysql命令行运行sql脚本):
sql脚本在https://github.com/alibaba/nacos配置文件中

不配置mysql:
docker run —env MODE=standalone —name nacos -d -p 28848:8848 nacos/nacos-server
配置mysql

docker  run --name nacos -p 8848:8848   \
--privileged=true \
--restart=always \
-e JVM_XMS=256m \
-e JVM_XMX=256m \
-e MODE=standalone \
-e PREFER_HOST_MODE=hostname \
-v /usr/local/docker/nacos/conf:/usr/local/docker/nacos/conf \
-v /usr/local/docker/nacos/conf/application.properties:/usr/local/docker/nacos/conf/application.properties \
-d nacos/nacos-server:latest

docker 配置nginx

docker 配置sentinel

https://blog.csdn.net/qiuchenxinlu/article/details/123114456

#拉镜像
docker pull bladex/sentinel-dashboard
#先修改下面的支持ip4转发
#启动
docker run --name sentinel -d -p 8858:8858 -d bladex/sentinel-dashboard

ip:8858,账号密码都是sentinel
错误点:报错:docker：IPv4 forwarding is disabled. Networking will not work.

vim /etc/sysctl.conf
#配置转发
net.ipv4.ip_forward=1
#保存退出就可以了
:wq!
#重启服务，让配置生效
systemctl restart network
#查看是否成功,如果返回为“net.ipv4.ip_forward = 1”则表示成功
sysctl net.ipv4.ip_forward
#重启docker,启动服务
