使用docker 遇到的问题

1、docker的centos中安装hiredis出现libhiredis.so.0.13: cannot open shared object file

vi /etc/profile

export LD_LIBRARY_PATH=/where/you/install/lib:$LD_LIBRARY_PATH

:wq 退出

source /etc/profile

 

2、阿里云ECS CoreOS 系统, docker 运行出错 Error response from daemon: error creating overlay mount to /var/lib/docker/overlay2/007018df729636dd7c3d22ea683d13b6f5f0657b7c2c9e0014c671id argument.

       #vi /etc/sysconfig/docker-storage       //将文件里的overlay2改成overlay即可 

       #systemctl start docker                         //修改后重启

3、Docker中service或systemctl无权限使用

    创建容器时指定：--privileged=true 和  /usr/sbin/init (/bin/bash替换成这个)

 

3、Cannot open self /usr/local/bin/docker-compose or archive /usr/local/bin/doc

       更换其他下载路径：curl -L https://github.com/docker/compose/releases/download/1.23.0-rc3/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

 

4、docker容器如何修改端口或增加端口？

1、systemctl stop docker     -- 先关闭docker服务

2、编辑配置文件（一般在“”/var/lib/docker/containers/container_id“”目录）

# vi hostconfig.json
"PortBindings":{
        "19501/tcp":[
            {
                "HostIp":"",
                "HostPort":"19501"
            }
        ]
    }
## 修改成
"PortBindings":{
        "19501/tcp":[
            {
                "HostIp":"",
                "HostPort":"19501"
            }
        ],
        "9501/tcp":[
            {
                "HostIp":"",
                "HostPort":"9501"
            }
        ]
    }
# vi config.v2.json
"ExposedPorts":{
            "19501/tcp":{

            }
        }
## 修改成
"ExposedPorts":{
            "19501/tcp":{

            },
            "9501/tcp":{

            }
        }

  3、systemctl start docker     -- 启动docker服务

5、docker容器如何添加或修改volume？

1、systemctl stop docker     -- 先关闭docker服务

2、编辑配置文件（一般在“”/var/lib/docker/containers/container_id“”目录）

# vi hostconfig.json
"Binds":[
        "/var/www:/var/www"
    ]
## 修改成
"Binds":[
        "/var/www:/var/www",
        "/mnt/hgfs:/mnt/hgfs"
    ]
# vi config.v2.json
"MountPoints":{
        "/var/www":{
            "Source":"/var/www",
            "Destination":"/var/www",
            "RW":true,
            "Name":"",
            "Driver":"",
            "Type":"bind",
            "Propagation":"rprivate",
            "Spec":{
                "Type":"bind",
                "Source":"/var/www",
                "Target":"/var/www"
            }
        }
    }
修改成
"MountPoints":{
        "/var/www":{
            "Source":"/var/www",
            "Destination":"/var/www",
            "RW":true,
            "Name":"",

                "Type":"bind",
                "Source":"/var/www",
                "Target":"/var/www"
            }
        },
        "/mnt/hgfs":{
            "Source":"/mnt/hgfs",
            "Destination":"/mnt/hgfs",
            "RW":true,
            "Name":"",
            "Driver":"",
            "Type":"bind",
            "Propagation":"rprivate",
            "Spec":{
