常用软件安装
1. 安装tomcat
1.1 搜索镜像
由于https://hub.docker.com 网站已经被禁，在线搜索可以选用国内的一些网址比如https://docker.aityp.com：
搜索tomcat,点击受验证：
拉取tomcat:9.0.93-jdk8镜像：
sh
[root@hadoop104 ~]# docker pull tomcat:9.0.93-jdk8如果拉取不下来，可以直接使用指定镜像库地址：
运行镜像，得到tomcat容器：
sh
[root@hadoop104 ~]# docker run -d -p 8080:8080 --name="tomcat8" tomcat:9.0.93-jdk8
bda88ee3743f6d53dd998a570720d765b6e346c50effd37af044dccd932cbd74
[root@hadoop104 ~]# docker ps

出现访问404，说明tomcat已经启动，但是不能看到tomcat猫，原因在于webapps以前默认的内容都转移到了webapp.dist目录中：
sh
[root@hadoop104 ~]# docker exec -it 7a7b744c2fce /bin/bash
root@7a7b744c2fce:/usr/local/tomcat# cd webapps

使用DBeaver客户端，远程连接mysql:
查看服务器数据目录：
3. 安装redis
3.1 拉取redis7.4.1
sh
[root@hadoop104 ~]# docker pull redis:7.4.13.2 启动redis镜像
sh
[root@hadoop104 redis]# docker run -p 6379:6379 --name "redis7" --privileged=true -v /redis/redis.conf:/etc/redis/redis.conf -v /redis/data:/data -d redis:7.4.1 redis-server /etc/redis/redis.conf
b3a71b36ad076984b1819f3ce6b5ea54c360a6affbfaff1695ad1088231e10443.3 配置redis
为了方便后续验证配置生效，配置databases只有8个：
sh
[root@hadoop104 redis]# cd /redis/
[root@hadoop104 redis]# vim redis.conf
[root@hadoop104 redis]# cat redis.conf

打开redis客户端RedisInsight，配置redis连接：
可以看到当前默认为0号库 
选择15号库，可以看到客户端报错没有15号库：
4. 安装nginx
参考后面教程Portainer
5. 搭建mysql主从复制
5.1 拉取MySQL镜像
sh
[root@hadoop102 ~]# docker pull swr.cn-north-4.myhuaweicloud.com/ddn-k8s/docker.io/mysql:8.0.40
## 修改镜像名称，方便后续使用
[root@hadoop102 ~]# docker tag swr.cn-north-4.myhuaweicloud.com/ddn-k8s/docker.io/mysql:8.0.40 mysql:8.0.405.2 新建主实例
sh
[root@hadoop102 ~]# mkdir -p /mysql-cluster/mysql-master/log
[root@hadoop102 ~]# mkdir -p /mysql-cluster/mysql-master/data
[root@hadoop102 ~]# mkdir -p /mysql-cluster/mysql-master/conf
[root@hadoop102 ~]# docker run -p 4306:3306 --name mysql-master \
--privileged=true \
-v /mysql-cluster/mysql-master/log:/var/log/mysql \

-v /mysql-cluster/mysql-master/conf:/etc/mysql/conf.d \
-e MYSQL_ROOT_PASSWORD=root \
-d mysql:8.0.40在/mysql-cluster/mysql-master/conf目录下，新建my.cnf
ini
[mysqld]
## 设置server_id，同一局域网中需要唯一
server_id=100
## 指定不需要同步的数据库名称
binlog-ignore-db=mysql
## 开启二进制日志功能
log-bin=mall-mysql-bin
## 设置二进制日志使用内存大小（事务）
binlog_cache_size=1M
## 设置使用的二进制日志格式（mixed,statement,row）
binlog_format=row
## 二进制日志过期清理时间。默认值为0，表示不自动清理。
expire_logs_days=7
## 跳过主从复制中遇到的所有错误或指定类型的错误，避免slave端复制中断。
## 如：1062错误是指一些主键重复，1032错误是因为主从数据库数据不一致
slave_skip_errors=1062重启master实例
sh
docker restart mysql-master进入mysql-master容器:
sh
docker exec -it mysql-master /bin/bash
mysql -uroot -proot
mysql> CREATE USER 'slave'@'%' IDENTIFIED BY '123456';
mysql> GRANT REPLICATION SLAVE,USAGE, REPLICATION CLIENT ON *.* TO 'slave'@'%';5.3 新建从实例
启动容器实例：
sh
docker run --privileged=true -p 4307:3306 --name mysql-slave \
-v /mysql-cluster/mysql-slave/log:/var/log/mysql \
-v /mysql-cluster/mysql-slave/data:/var/lib/mysql \
-v /mysql-cluster/mysql-slave/conf:/etc/mysql/conf.d \
-e MYSQL_ROOT_PASSWORD=root \
-d mysql:8.0.40在/mysql-cluster/mysql-slave/conf目录下，新建my.cnf
ini
[mysqld]
## 设置server_id，同一局域网中需要唯一
server_id=102
## 指定不需要同步的数据库名称
binlog-ignore-db=mysql
## 开启二进制日志功能，以备Slave作为其它数据库实例的Master时使用
log-bin=mall-mysql-slave1-bin
## 设置二进制日志使用内存大小（事务）
binlog_cache_size=1M
## 设置使用的二进制日志格式（mixed,statement,row）
binlog_format=row
## 二进制日志过期清理时间。默认值为0，表示不自动清理。
expire_logs_days=7
## 跳过主从复制中遇到的所有错误或指定类型的错误，避免slave端复制中断。
## 如：1062错误是指一些主键重复，1032错误是因为主从数据库数据不一致
slave_skip_errors=1062
## relay_log配置中继日志
relay_log=mall-mysql-relay-bin
## log_slave_updates表示slave将复制事件写进自己的二进制日志
log_slave_updates=1
## slave设置为只读（具有super权限的用户除外）
read_only=1修改完配置后重启slave实例:
sh
docker restart mysql-slave5.4 在主数据库中查看主从同步状态
sh
[root@hadoop102 ~]# docker exec -it mysql-master /bin/bash
bash-5.1# mysql -uroot -p
