docker中tomcat/mysql/redis安装与启动

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_%';

• 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
