环境申请

由于环境要国产化，选择openEuler 22.03 LTS系统，这里测试一下在openEuler上安装PG，过程如下。

代码语言：javascript 复制

docker rm -f lhropeneuler22
docker run -itd --name lhropeneuler22 -h lhropeneuler22 \
-p 15432:5432 -p 7389:3389 \
--privileged=true \
-v /sys/fs/cgroup:/sys/fs/cgroup \
lhrbest/openeuler22:2.0 \
init

docker exec -it lhropeneuler22 bash 

[root@lhropeneuler22 /]# cat /etc/os-release 
NAME="openEuler"
VERSION="22.03 LTS"
ID="openEuler"
VERSION_ID="22.03"
PRETTY_NAME="openEuler 22.03 LTS"
