全网独家：基于openEuler-20.03-LTS-SP4底包构建opengaussV5.0.1LTS的单机极简版数据库容器

本文尝试基于openEuler-20.03-LTS-SP4底包构建opengaussV5.0.1LTS的单机版极简版数据库容器。

一、软件包源

下载并重命名为：openGauss-5.0.1-openEuler-64bit-2003sp4.tar.bz2

3、当前准备情况

[root@localhost opengauss]# ll

二、容器制作

1、导入openEuler-20.03-LTS-SP3镜像

[root@localhost opengauss]# docker load -i openEuler-20.03-LTS-SP4-docker.x86_64.tar.xz 
5d8f141db76b: Loading layer [==================================================>]  309.9MB/309.9MB
Loaded image: openeuler-20.03-lts-sp4:latest
[root@localhost opengauss]# docker images
REPOSITORY                TAG                 IMAGE ID            CREATED             SIZE

2、启动实例

[root@localhost opengauss]# docker run -itd --restart=always --name opengauss  --privileged -p 5432:5432 -v /data/opengaussdata:/var/lib/opengauss -v /etc/localtime:/etc/localtime:ro  openeuler-20.03-lts-sp4:latest /bin/bash

[root@localhost opengauss]# docker ps

3、将安装文件拷贝至容器挂载目录内

[root@localhost opengauss]# cp openGauss-5.0.1-openEuler-64bit-2003sp4.tar.bz2 /data/opengaussdata/
[root@localhost opengauss]# ll /data/opengaussdata
总用量 97M
-rw-r--r-- 1 root root 97M  1月 10 15:24 openGauss-5.0.1-openEuler-64bit-2003sp4.tar.bz2
[root@localhost opengauss]# docker exec -it opengauss /bin/bashWelcome to 5.10.0-60.18.0.50.oe2203.x86_64System information as of time:  Wed Jan 10 16:55:36 CST 2024System load:    0.00

4、确认容器字符集并修改限制（在容器内操作）

[root@4e720ca39846 /]# echo $LANG
en_US.UTF-8
[root@4e720ca39846 /]# echo "* soft nofile 1000000" >> /etc/security/limits.conf
[root@4e720ca39846 /]# echo "* hard nofile 1000000" >> /etc/security/limits.conf
[root@4e720ca39846 /]# echo "* soft nproc unlimited" >> /etc/security/limits.d/90-nproc.conf
[root@4e720ca39846 /]# tail -n 2 /etc/security/limits.conf
* soft nofile 1000000
* hard nofile 1000000
[root@4e720ca39846 /]# tail -n 1 /etc/security/limits.d/90-nproc.conf
* soft nproc unlimited
