騰訊的 TencentOS Server 4.4 服務器系統

docker使用的是yum安裝的版本

問題現象

docker創建的mysql 5.7.44容器（官方鏡像）無法正常啟動，隔幾秒就重啟

docker logs mysql 打印：

進入到容器手動運行mysqld命令也沒有有用的信息，會在光標卡一段時間后提示killed。

查找資料

很幸運谷歌到了一個issues：官方docker github里的issuse

里面的回復：

Hello,I know this post is old, nevertheless, for those who come across it in the future like me, this solution allows resolving the issue without intervening in the host system configuration:---
version: '3.6'
services:mysql:image: mysql:5.7ulimits:nofile: # Fix memory leak issue on some systems when LimitCORE=infinity (containerd)soft: 1048576hard: 1048576
This is a configuration for Compose (Docker plugin). However, you can use the equivalent, such as docker run mysql:5.7 --ulimit nofile=1048576:1048576.For your information, I encountered a similar issue with the library/elasticsearch:2.4-alpine image.I use Fedora Workstation Silverblue 39

我原來運行的命令：

docker run -d --name mysql \
-v /app/mysql/binlogs:/ava_app/mysql/binlogs \
-v /app/mysql/conf:/etc/mysql \
-v /app/mysql/logs:/var/log/mysql \
-v /data/upload:/ava_data/upload \
-v /etc/localtime:/etc/localtime:ro \
-v /app/timezone:/etc/timezone:ro \
-e "MYSQL_ROOT_PASSWORD=xxxxxxxxxxxx" \
--restart always --network=host mysql:5.7.44

根據上面方法改進的命令：

# 加入 --ulimit nofile=1048576:1048576 
docker run -d --ulimit nofile=1048576:1048576 --name mysql \
-v /app/mysql/binlogs:/ava_app/mysql/binlogs \
-v /app/mysql/conf:/etc/mysql \
-v /app/mysql/logs:/var/log/mysql \
-v /data/upload:/ava_data/upload \
-v /etc/localtime:/etc/localtime:ro \
-v /app/timezone:/etc/timezone:ro \
-e "MYSQL_ROOT_PASSWORD=xxxxxxxxxxxx" \
--restart always --network=host mysql:5.7.44

解決

后續根據“ docker mysql ulimit ”關鍵詞查到的幾個文章
