Restart mysql container report error messages: Could not connect to mysql server. Aborting... #16

fye · 2015-06-19T02:38:58Z

I restart my mysql containers, according to the 'docker logs - tf mysql' command to check the log information to quote the following error:

Could not connect to mysql server. Aborting...

Could you tell me what could be the cause?

sameersbn · 2015-06-19T08:08:36Z

@fye can you provide the command sequence to reproduce this?

fye · 2015-06-23T01:58:30Z

Do you mean this:

sameersbn · 2015-06-23T07:19:37Z

@fye the complete docker run command would be helpful, you can mask out the passwords if any.

I used the following

docker run -it --name=mysql \
  --env='DB_USER=avatar' --env='DB_PASS=password' --env='DB_NAME=jira,confluence' \
  sameersbn/mysql

No problems seen with repeatedly running..

docker stop mysql
docker start mysql

fye · 2015-06-23T07:28:19Z

sorry, I misunderstand. This is my command:

mkdir -p /opt/mysql/data2
sudo chcon -Rt svirt_sandbox_file_t /opt/mysql/data2

docker run --name confluence-mysql2 -d
-p 3307:3306
-e 'DB_USER=avatar' -e 'DB_PASS=avatar' -e 'DB_NAME=confluence,jira'
-v /opt/mysql/data2:/var/lib/mysql sameersbn/mysql:latest

fye · 2015-06-23T07:38:51Z

one more descripton:

/opt/mysql/data2 directory is the first I created by the following commands:

mkdir -p /opt/mysql/data2
sudo chcon -Rt svirt_sandbox_file_t /opt/mysql/data2

docker run --name confluence-mysql  -d \
  -p 3307:3306 \
  -e 'DB_USER=ezview' -e 'DB_PASS=ezview' -e 'DB_NAME=confluence,jira' \
  -v /opt/mysql/data2:/var/lib/mysql sameersbn/mysql:latest

And then create good container, after running for a period of time, confluence was also produced a lot of data. Server restart after a few days ago, I found that direct execution command:

docker start confluence-mysql

command, so the error: Could not connect to mysql server. Aborting...

Then I try to generate a new container, which is the command:

mkdir -p /opt/mysql/data2
sudo chcon -Rt svirt_sandbox_file_t /opt/mysql/data2

docker run --name confluence-mysql2  -d \
  -p 3307:3306 \
  -e 'DB_USER=ezview' -e 'DB_PASS=ezview' -e 'DB_NAME=confluence,jira' \
  -v /opt/mysql/data2:/var/lib/mysql sameersbn/mysql:latest

Also report the error: Could not connect to mysql server. Aborting...

fye · 2015-06-23T07:43:12Z

The attach is my docker container list:

sameersbn · 2015-06-23T12:17:45Z

@fye can you pull down the updated latest tag from the docker and retry

docker pull sameersbn/mysql:latest

There was one particular use case that was fixed recently. Can you test with the updated image.

sameersbn · 2015-06-23T12:20:18Z

@fye if that does not help, please test after disabling selinux with setenforce 0 to make sure that selinux is not causing any issue. It probably is not, but just to be sure.

fye · 2015-06-24T05:16:01Z

@sameersbn , I found my problems. I use the following command, that is ok:

docker run --name confluence-mysql2  -d \
  -p 3307:3306 \
  -v /opt/mysql/data2:/var/lib/mysql sameersbn/mysql:latest

docker stop confluence-mysql2
docker start confluence-mysql2

also works.

sameersbn · 2015-06-24T06:50:00Z

@fye what was the problem?

fye · 2015-06-24T07:23:10Z

@sameersbn , I don't know why, I removed the following args:

-e 'DB_USER=ezview' -e 'DB_PASS=ezview' -e 'DB_NAME=confluence,jira'

fye · 2015-06-24T07:27:14Z

And i followed your method, include disabled selinux with setenforce 0, that's not ok, same error like before.
I removed the above args, then worked fine.

sameersbn · 2015-06-24T17:05:23Z

@fye did you try updating the sameersbn/mysql image?

fye · 2015-07-01T14:26:49Z

@sameersbn , Yes, I had update the image, also the same error.

sameersbn · 2015-07-01T15:23:07Z

@fye got it.

netflash · 2015-12-21T13:31:30Z

Got same error
here's my docker-compose file

@netflash Looks like you have stopped containers which docker-compose is reusing, can you remove the stopped containers before retrying. Also you may want to pull the most recent image from the docker hub.

Here are my test results:

Looks we could close ticket.

plori · 2019-02-20T09:58:41Z

Hi,

I know this is a very old issue.

We had a similar problem, when restarting the mysql-redmine docker container. It boiled down to the modified mysql root user password (we just dont want to have none).
As you can see from the following lines, the mysql root user is used to test for a running server. But since we changed the password it can not access the database in line 78...

docker-mysql/entrypoint.sh

Lines 71 to 88 in b33e19d

    
           # start mysql server 
        
           echo "Starting MySQL server..." 
        
           /usr/bin/mysqld_safe >/dev/null 2>&1 & 
        
           # wait for mysql server to start (max 30 seconds) 
        
           timeout=30 
        
           echo -n "Waiting for database server to accept connections" 
        
           while ! /usr/bin/mysqladmin -u root status >/dev/null 2>&1 
        
           do 
        
             timeout=$(($timeout - 1)) 
        
             if [ $timeout -eq 0 ]; then 
        
               echo -e "\nCould not connect to database server. Aborting..." 
        
               exit 1 
        
             fi 
        
             echo -n "." 
        
             sleep 1 
        
           done 
        
           echo

Possibly there should be a more robust way in checking for database status, but I am not really that experienced to provide a solution.
