在docker容器中連接宿主機中的mysql

1. 查看宿主機和docker之間的橋接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  (以太網)
        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

# 宿主機在與容器同一局域網的IP地址一般是docker0對應的IP地址段的首個地址
即（172.17.0.1 ）

2. 在容器中連接宿主機的mysql

$ mysql -h 172.17.0.1 -u root -p
