docker 安装开发环境 - (3)安装redis

接着上一篇文章继续操作

查看容器

[river@bogon ~]$ sudo docker ps 
[sudo] password for river: 
CONTAINER ID        IMAGE                  COMMAND             CREATED             STATUS              PORTS                    NAMES
de749d8aff6c        river/centos-1         "init"              17 minutes ago      Up 17 minutes       0.0.0.0:3306->3306/tcp   epic_khayyam

进入容器

[river@bogon ~]$ sudo docker exec -it de749d8aff6c bash
[root@de749d8aff6c /]# su river
[river@de749d8aff6c /]$ 

在CentOS和Red Hat系统中，首先添加EPEL仓库，然后更新yum源：

sudo yum install epel-release
sudo yum update

然后安装Redis数据库：

sudo yum -y install redis

安装好后启动Redis服务即可：

[river@de749d8aff6c /]$ sudo systemctl enable redis
Created symlink from /etc/systemd/system/multi-user.target.wants/redis.service to /usr/lib/systemd/system/redis.service.
[river@de749d8aff6c /]$ sudo systemctl start redis
[river@de749d8aff6c /]$ sudo systemctl status redis

[river@de749d8aff6c /]$ 

配置Redis能被远程连接

vi /etc/redis.conf
需要修改的地方：
改绑定地址：
bind 0.0.0.0
注释掉发现没起作用（#bind 127.0.0.1）

保存镜像

[river@bogon ~]$ sudo docker commit -m="has mysql" -a="river" de749d8aff6c river/centos-2
[sudo] password for river:
sha256:e17a41ef44dcee0e06a99da36b146fbcdcf52bd573a50cbbde1780d6c06ea3dc
