在docker容器中连接宿主机中的mysql


  1. 查看宿主机和docker之间的桥接ip
$ ifconfig
docker0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 172.17.0.1  netmask 255.255.0.0  broadcast 172.17.255.255
        inet6 fe80::42:8aff:febc:8533  prefixlen 64  scopeid 0x20<link>
        ether 02:42:8a:bc:85:33  txqueuelen 0  (以太网)
        RX packets 4779  bytes 11624681 (11.6 MB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 6006  bytes 441594 (441.5 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

# 宿主机在与容器同一局域网的IP地址一般是docker0对应的IP地址段的首个地址
即(172.17.0.1 )
  1. 在容器中连接宿主机的mysql
$ mysql -h 172.17.0.1 -u root -p
