Docker安装常用服务命令笔记
Docker安装MySql
首先可能需要将docker仓库地址改成阿里云的
修改配置文件，路径在/etc/docker/daemon.json
修改为：
{
"registry-mirrors": ["https://ubih6qcd.mirror.aliyuncs.com"]
}
然后刷新配置文件，重启docker
sudo systemctl daemon-reload
sudo systemctl restart docker
拉取mysql5.7镜像
docker pull mysql:5.7
不挂载数据启动
启动mysql容器，并设置密码和默认字符集和时区
docker run -d --name mysql57 -p 3306:3306 -e TZ=Asia/Shanghai -e MYSQL_ROOT_PASSWORD=@LovelyLM mysql:5.7 --character-set-server=utf8mb4
挂载数据到宿主机启动
如果我们需要将数据文件、日志文件、配置文件挂载到宿主机，需要首先在宿主机创建相应文件夹，我习惯在/home/docker/mysql/mysql57目录放置所有相关文件，分别是配置文件、数据文件、日志文件目录结构如下：
然后再到conf目录创建一个my.conf的空文件，这是mysql的默认配置文件，以后我们直接修改这里就行了
启动mysql容器，并挂载数据到主机
我这里将mysql设置了自启动
docker run -d --name mysql57 -p 3306:3306 --restart=always -v /home/docker/mysql/mysql57/data:/var/lib/mysql -v /home/docker/mysql/mysql57/conf:/etc/mysql -v /home/docker/mysql/mysql57/log:/var/log/mysql -e TZ=Asia/Shanghai -e MYSQL_ROOT_PASSWORD=@LovelyLM mysql:5.7 --character-set-server=utf8mb4
Docker安装canal
为了更好的配置canal，一般推荐将canal配置文件挂载再宿主机
首先拉取canal最新镜像
docker pull canal/canal-server
先启动服务：
docker run --name canal -d canal/canal-server
我创建了关于canal的目录，结构如下：
canal有两个配置文件，canal.properties和instance.properties，我们都需要将它们复制到宿主机，此外，我们还可以把日志文件一同也复制
以下路径，左边是容器内部的，右边是宿主机的
docker cp canal:/home/admin/canal-server/conf/canal.properties /home/docker/canal/conf
docker cp canal:/home/admin/canal-server/conf/example/instance.properties /home/docker/canal/conf
docker cp canal:/home/admin/canal-server/logs/canal/canal.log /home/docker/canal/log
docker cp canal:/home/admin/canal-server/logs/canal/canal_stdout.log /home/docker/canal/log
复制完成后，主机目录就会多出两个文件：
log文件夹也会多出两个文件：
这里将两个文件的默认信息贴一下：
canal.properties

将刚刚启动的容器先停止再删除
docker stop canal
docker rm canal
重新以文件挂载的方式启动canal
我这里将canal设置了自启动
docker run --name canal -p 11111:11111 -d --restart=always -v /home/canal/instance.properties:/home/docker/canal/conf/instance.properties -v /home/canal/canal.properties:/home/docker/canal/conf/canal.properties -v /home/admin/canal-server/logs/canal:/home/docker/canal/log canal/canal-server
Docker安装rabbitmq（自带管理界面版本）
首先拉取最新镜像：
docker pull rabbitmq:management
同样的，我们选择挂载数据，在主机创建文件夹：
挂载文件启动：
docker run -d --name rabbitmq -p 5671:5671 -p 5672:5672 -p 15672:15672 -p 15671:15671 -p 25672:25672 -p 4369:4369 --restart=always -v /opt/rabbitmq/data/:/home/docker/rabbitmq/data rabbitmq:management
Docker安装redis（单机版）
如果是安装单机版redis，推荐使用官方的轻量级镜像：
docker pull redis:alpine3.16
启动redis容器并设置密码
强烈推荐设置密码，不然在云服务器上极有可能被人攻击
docker run -d --name redis --restart=always -p 6379:6379 redis:alpine3.16 --requirepass "@LovelyLM"
额外：canal配置mysql与rabbitmq
需要开启mysql的binlog日志：
