PG启动报错

[root@localhost data]# docker logs postgres
popen failure: Cannot allocate memory
initdb: error: The program “postgres” is needed by initdb but was not found in the
same directory as “/usr/lib/postgresql/12/bin/initdb”.
Check your installation.

但是换个镜像就没题目，应该是镜像跟体系不匹配吧，发起换镜像吧
docker pull postgres:bullseye
拉取镜像

1. docker pull postgres:12.17-bullseye

复制代码

启动镜像

1. docker run --name postgres1217 -e POSTGRES_PASSWORD=PGdata@456  -p 5432:5432 -v /data/postgres/postgresql/data:/var/lib/postgresql/data -d postgres:12.17-bullseye

复制代码

查看容器状态

1. docker ps -a

复制代码

开放端口

1. firewall-cmd --add-port=5432/tcp
3. firewall-cmd --add-port=5432/tcp --permanent

复制代码
