Docker：除非我手动重启，否则MySQL会拒绝主机IP

Here is my Dockerfile:

这是我的Dockerfile:

FROM debian:jessie-backports

RUN apt-get update --yes && apt-get upgrade --yes

RUN sed -i -e"s/^#max_connections\s*=\s*100/max_connections = 200/" /etc/mysql/my.cnf
RUN echo "\n[mysqld]\nskip-grant-tables\n" >> /etc/mysql/my.cnf

# REDIS SETUP

VOLUME ["/var/lib/redis", "/var/log/redis"]

EXPOSE 6379 6380

# ELASTICSEARCH SETUP

RUN sed 's/^#START_DAEMON=true/START_DAEMON=true/' -i /etc/default/elasticsearch

VOLUME ["/opt/elasticsearch/data", "/opt/elasticsearch/logs"]

EXPOSE 9200 9300

ADD docker-entrypoint.sh /usr/local/bin/docker-entrypoint.sh
RUN chmod 777 /usr/local/bin/docker-entrypoint.sh
ENTRYPOINT ["/usr/local/bin/docker-entrypoint.sh"]

The entrypoint:

#!/bin/bash

/etc/init.d/mysql start
/etc/init.d/redis-server start
/etc/init.d/elasticsearch start
/bin/bash

And the command I'm running to start the container:

我正在运行的命令启动容器:

docker run -i -t -p 3306:3306 -p 6379:6379 -p 9200:9200 -p 9300:9300 assethost

I want to connect to the MySQL server running in the container from the host, but this is what happens when I try to connect:

我想从主机连接到容器中运行的MySQL服务器,但这是我尝试连接时发生的情况:

ERROR 1130 (HY000): Host '192.168.99.1' is not allowed to connect to this MySQL server

错误1130(HY000):主机'192.168.99.1'不允许连接到此MySQL服务器

Both Redis and Elasticsearch expose themselves just fine. MySQL will only begin accepting external hosts if I restart it manually from the Bash shell that comes up from the entrypoint when I run the container. I have to run /etc/init.d/mysql restart. Only then, can I successfully connect from the host using the MySQL client.

Redis和Elasticsearch都暴露自己很好。如果我从运行容器时从入口点出来的Bash shell手动重启它,MySQL才会开始接受外部主机。我必须运行/etc/init.d/mysql restart。只有这样,我才能使用MySQL客户端从主机成功连接。

Note that I am using docker-machine, so I have to give the MySQL client the host IP in order to connect.

请注意,我使用的是docker-machine,所以我必须给MySQL客户端提供主机IP才能连接。

How can I be able to connect from the host to the MySQL instance running in the container without having to manually restart MySQL?

如何能够从主机连接到容器中运行的MySQL实例,而无需手动重启MySQL?

I figured out a way to get the skip-grant-tables option to be applied on start.

我想出了一种方法,可以在启动时应用skip-grant-tables选项。

Workaround

In docker-entrypoint.sh, I changed /etc/init.d/mysql start to

在docker-entrypoint.sh中,我将/etc/init.d/mysql更改为

HOME=/etc/mysql /usr/bin/mysqld_safe > /dev/null 2>&1 &

HOME = / etc / mysql / usr / bin / mysqld_safe> / dev / null 2>&1&

Other changes

Since there was already a [mysqld] section in my.cnf, I changed the following line in Dockerfile RUN echo "\n[mysqld]\nskip-grant-tables\n" >> /etc/mysql/my.cnf

由于my.cnf中已经存在[mysqld]部分,我在Dockerfile RUN echo中更改了以下行“\ n [mysqld] \ nskip-grant-tables \ n”>> /etc/mysql/my.cnf

RUN sed -i '/\[mysqld\]/ a skip-grant-tables\nskip-name-resolve' /etc/mysql/my.cnf

运行sed -i'/ \ [mysqld \] / a skip-grant-tables \ nskip-name-resolve'/etc/mysql/my.cnf

I added skip-name-resolve so mysql doesn't attempt to resolve names for local ip addresses.

我添加了skip-name-resolve,因此mysql不会尝试解析本地IP地址的名称。

Caveats

The workaround no longer works when /etc/init.d/mysql restart is executed, but /etc/init.d/mysql stop; /etc/init.d/mysql start preserved the 'skip-grant-tables' option.

执行/etc/init.d/mysql restart时,解决方法不再有效,但/etc/init.d/mysql停止; /etc/init.d/mysql start保留了'skip-grant-tables'选项。
