1、Docker安装redis
（1）下载redis
利用docker pull redis命令下载reids，如果不指定版本的情况下默认是使用的最新版本
（2）启动redis
docker run -p 6379:6379 --name myredis -v /usr/local/docker/redis.conf:/etc/redis/redis.conf -v /usr/local/docker/data:/data -d redis redis-server /etc/redis/redis.conf --appendonly yes
-p 6379:6379 端口映射：前表示主机部分，：后表示容器部分。
--name ：指定该容器名称，操作容器的时候可以使用名称，如退出与开启容器
-v 挂载目录，规则与端口映射相同，docker是个沙箱隔离级别的容器，这个是它的特点及安全机制，不能随便访问外部（主机）资源目录，所以需要这个挂载目录机制
redis.conf是redis的配置文件
-d redis 表示后台启动redis
--appendonly yes 开启redis 持久化
（3）查看是否启动成功
[root@aubin ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 63a13b7ef4dd redis "docker-entrypoint.s猞" 32 seconds ago Up 29 seconds 0.0.0.0:6379->6379/tcp myredis
（4）查看redis容器的日志
[root@aubin ~]# docker logs myredis 1:C 23 Oct 2020 01:21:49.446 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo 1:C 23 Oct 2020 01:21:49.447 # Redis version=6.0.8, bits=64, commit=00000000, modified=0, pid=1, just started 1:C 23 Oct 2020 01:21:49.447 # Configuration loaded 1:M 23 Oct 2020 01:21:49.451 * Running mode=standalone, port=6379. 1:M 23 Oct 2020 01:21:49.451 # WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128. 1:M 23 Oct 2020 01:21:49.451 # Server initialized 1:M 23 Oct 2020 01:21:49.451 # WARNING overcommit_memory is set to 0!

（5）退出(停止运行中的容器)
SIGTERM（终止进程）信号后等待一段时间后(默认是10s，可以通过-t 参数来修改)，如果从containerd 收到了容器退出消息，那么容器退出成功。如果超过等待的时间之后，还是没收到容器退出的消息，那么docker 将使用docker kill方式试图终止容器
[root@aubin ~]# docker stop myredis
myredis
（6）启动（启动一个或多个已经被停止的容器）
[root@aubin ~]# docker start myredis
myredis
（7）redis连接redis-server
[root@aubin ~]# docker exec -it myredis redis-cli 127.0.0.1:6379> set 1 1 OK 127.0.0.1:6379> get 1 "1"
关闭：
127.0.0.1:6379> shutdown [root@aubin ~]#
2、Docker安装mysql
（1）pull
[root@aubin tomcat9]# docker pull mysql:5.6 5.6: Pulling from library/mysql babf97a3f00a: Pull complete 88031ca211be: Pull complete be1b1d426cba: Pull complete ff53757c5bd8: Pull complete 53127b7bc50a: Pull complete e4f269bc946e: Pull complete 0c0f95c5641f: Pull complete a6eefa19530d: Pull complete 12d1cff28e35: Pull complete 79d2fe725964: Pull complete 869cdc62084e: Pull complete Digest: sha256:8875725ff152f77e47a563661ea010b4ca9cea42d9dda897fb565ca224e83de2 Status: Downloaded newer image for mysql:5.6 docker.io/library/mysql:5.6 [root@aubin tomcat9]#
（2）查看
[root@aubin tomcat9]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE zhai/centos latest 8f28e3fd97da 19 hours ago 215MB tomcat latest 625b734f984e 26 hours ago 648MB mysql 5.6 c580203d8753 28 hours ago 302MB redis latest bd571e6529f3 10 days ago 104MB mongo latest ba0c2ff8d362 4 weeks ago 492MB centos latest 0d120b6ccaa8 2 months ago 215MB hello-world latest bf756fb1ae65 9 months ago 13.3kB tomcat 8.5.32 5808f01b11bf 2 years ago 463MB [root@aubin tomcat9]#
（3）启动镜像
docker run -p 12345:3306
--name mysql
-v /zzyyuse/mysql/conf:/etc/mysql/conf.d
-v /zzyyuse/mysql/logs:/logs
-v /zzyyuse/mysql/data:/var/lib/mysql
-e MYSQL_ROOT_PASSWORD=123456
-d mysql:5.6
-p 12345:3306：将主机的12345端口映射到docker容器的3306端口。 --name mysql：运行服务名字 -v /zzyyuse/mysql/conf:/etc/mysql/conf.d ：将主机/zzyyuse/mysql录下的conf/my.cnf 挂载到容器的 /etc/mysql/conf.d -v /zzyyuse/mysql/logs:/logs：将主机/zzyyuse/mysql目录下的 logs 目录挂载到容器的 /logs。 -v /zzyyuse/mysql/data:/var/lib/mysql ：将主机/zzyyuse/mysql目录下的data目录挂载到容器的 /var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456：初始化 root 用户的密码。 -d mysql:5.6 : 后台程序运行mysql5.6
查看是否成功运行：
[root@aubin tomcat9]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 89c7173b7764 mysql:5.6 "docker-entrypoint.s猞" About a minute ago Up About a minute 0.0.0.0:12345->3306/tcp mysql
（4）交互式运行
[root@aubin tomcat9]# docker exec -it mysql /bin/bash
root@89c7173b7764:/#
（5）登录mysql

（6）sqlYog连接mysql
在sql中创建数据库并写入数据：
在docker中的mysql容器中查看数据：
mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | db_test | | mysql | | performance_schema | +--------------------+ 4 rows in set (0.00 sec) mysql> use db_test; Database changed mysql> show tables; +-------------------+ | Tables_in_db_test | +-------------------+ | test | +-------------------+ 1 row in set (0.00 sec) mysql> select * -> from test; +-------+ | name | +-------+ | ma | | zhai | | zhang | +-------+ 3 rows in set (0.00 sec) mysql>
