sql timeout

Steps:

1. Create a new rule for jmwrapid:

   INSERT INTO mysql_query_rules (active, username, match_pattern, replace_pattern, timeout, flagIN, destination_hostgroup)
   VALUES (1, 'jmwrapid', '.*', 'SET SESSION max_execution_time=30000;', 0, 0, 10);
   

   This rule sets a maximum execution time of 30 seconds (30000 milliseconds) for all queries executed by the jmwrapid user.

2. Load the rule into runtime and save it:

   LOAD MYSQL QUERY RULES TO RUNTIME;
   SAVE MYSQL QUERY RULES TO DISK;
   

3. Verify the rule:

   SELECT * FROM mysql_query_rules WHERE username = 'jmwrapid';
   

This will apply the SQL timeout specifically for jmwrapid. Let me know if you need more adjustments!

UPDATE mysql_query_rules
SET timeout = 60 
WHERE username = 'jmwrapid' AND match_pattern = '.*';

INSERT INTO mysql_query_rules (active, username, match_pattern, timeout, flagIN, destination_hostgroup)
VALUES (1, 'jmwrapid', '.*', 60, 0, 10);

To update a Docker container's timezone, you can follow these steps:

---

1. Update Timezone in a Running Container

If the container is already running, you can change the timezone by:

a. Using exec to set the timezone

Run the following command to set the timezone in the container:

docker exec -it <container_name> ln -sf /usr/share/zoneinfo/<Region>/<City> /etc/localtime

For example, to set the timezone to America/New_York:

docker exec -it <container_name> ln -sf /usr/share/zoneinfo/America/New_York /etc/localtime

b. Set the timezone environment variable

You can also set the TZ environment variable in the container:

docker exec -it <container_name> sh -c "echo 'America/New_York' > /etc/timezone && dpkg-reconfigure -f noninteractive tzdata"

---

2. Set Timezone at Container Creation

To ensure the correct timezone is set when you start a container, you can configure the timezone during container creation.

a. Add a TZ environment variable

Use the -e flag to set the TZ environment variable:

docker run -e TZ=America/New_York -d <image_name>

b. Mount the /etc/localtime file

You can mount the host system's timezone file into the container:

docker run -v /etc/localtime:/etc/localtime:ro -v /etc/timezone:/etc/timezone:ro -d <image_name>

This ensures the container uses the same timezone as the host system.

---

3. Update Dockerfile for Persistent Changes

If you want all containers created from a specific image to have a pre-configured timezone, you can modify the Dockerfile:

FROM <base_image>
ENV TZ=America/New_York
RUN ln -sf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone

Then rebuild the image:

docker build -t <new_image_name> .

---

4. Verify the Timezone

You can verify the timezone in the container by checking the current date and time:

docker exec -it <container_name> date

---

Summary:

• Use docker exec to update the timezone in a running container.
• Configure the timezone at container creation using -e TZ or mounting /etc/localtime.
• Modify the Dockerfile for persistent timezone settings.

Let me know if you need further clarification!

docker exec --user root -it proxysql ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

echo 'Asia/Shanghai' > /etc/timezone && dpkg-reconfigure -f noninteractive tzdata

docker exec -it proxysql mysql -h 127.0.0.1 -u admin -padmin -P6032 -e "SET GLOBAL time_zone = 'Asia/Shanghai';"

docker exec -it gzii-db-3 mysql -u root -h 127.0.0.1 -pwc97fjvDg:Ywgyad mysql -e "SET GLOBAL time_zone = 'Asia/Shanghai';" 

docker cp /usr/share/zoneinfo/Asia/Shanghai gzii-db-3:/usr/share/zoneinfo/Asia/Shanghai
docker exec -it -u root gzii-db-3 sh -c "echo 'Asia/Shanghai' > /etc/timezone"
docker exec -u root gzii-db-3 ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

docker cp /usr/share/zoneinfo/Asia/Shanghai gzii-db-4:/usr/share/zoneinfo/Asia/Shanghai
docker exec -it -u root gzii-db-4 sh -c "echo 'Asia/Shanghai' > /etc/timezone"
docker exec -u root gzii-db-4 ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
