本文详细介绍了如何在Docker环境下安装并启动Tomcat、MySQL和Redis。针对高版本Tomcat无法访问localhost的问题，提出了删除webapps并重命名webapps.dist的解决方案。对于MySQL，强调了数据持久化的重要性，并展示了设置初始密码和修改字符集的步骤。对于Redis，重点在于启动配置，包括修改redis.conf以允许远程访问。整个过程旨在提供一个稳定的容器化部署实践。

tomcat

建议使用tomcat8

[root@localhost ~]# docker pull tomcat:8.0.18-jre8

高版本tomcat无法访问localhost：8080解决方案
删除webapps
将webapps.dist改名为webapps

root@79f8d8d24ced:/usr/local/tomcat# rm -rf webapps
root@79f8d8d24ced:/usr/local/tomcat# mv webapps.dist webapps

启动

[root@localhost ~]# docker run -d -p 8080:8080 tomcat:8.0.18-jre8

mysql

查看是否已经启动mysql服务

[root@localhost ~]# ps -ef|grep mysql
root       9357   9256  0 19:35 pts/3    00:00:00 grep --color=auto mysql

挂载容器卷，防止数据丢失

[root@localhost ~]# docker run -d -p 3306:3306 --privileged=true 
                   -v /chet/mysql/log:/var/log/mysql 
                   -v /chet/mysql/data:/var/lib/mysql 
                   -v /chet/mysql/conf:/etc/mysql/conf.d -e MYSQL_ROOT_PASSWORD=root mysql

启动

[root@localhost ~]# docker ps

修改字符集，防止中文乱码
主机上指定容器卷目录下新建my.cnf，此时目录为/chet/mysql/conf
修改文件内容

[client]
default_character_set=utf8mb4
[mysqld]
character-set-server=utf8mb4

重启MySQL容器
查看字符集

mysql> show variables like 'character_set_%';
+--------------------------+--------------------------------+
| Variable_name            | Value                          |

修改成功

redis

宿主机创建redis.conf
注意：粘贴对应版本的redis.conf文件
修改参数

# bind 127.0.0.1 -::1
protected-mode yes
daemonize no

启动redis

 docker run -d -p 6379:6379 --privileged=true  --name r1 -v /redis/redis.conf:/etc/redis/redis.conf -v /redis/data:/data  redis redis-server /etc/redis/redis.conf

若启动失败
docker logs r1
