如何在Docker中的CentOS上运行PostgreSQL？

我运行了centos：7.1.1503然后yum install postgresql.不幸的是,由于系统问题我甚至在安装initscripts之后无法运行postgresql服务：

Redirecting to /bin/systemctl start  postgresql.service

 You could try using --skip-broken to work around the problem

我现在能做什么？我正在考虑从头开始构建它并以这种方式工作.

最佳答案

不要打扰systemd,直接运行Postgres.下面显示了如何在基础Centos7容器中运行Postgres：

$docker run -it centos:centos7 /bin/bash
bash-4.2$yum install postgresql-server sudo
[..snip..]
bash-4.2$sudo -u postgres /usr/bin/initdb /var/lib/pgsql/data/
bash-4.2$sudo -u postgres /usr/bin/pg_ctl start \
   -D /var/lib/pgsql/data -s -o "-p 5432" -w -t 300
bash-4.2$ps -eo pid,args
  PID COMMAND
    1 /bin/bash
  118 /usr/bin/postgres -D /var/lib/pgsql/data -p 5432
  119 postgres: logger process   
  121 postgres: checkpointer process   
  122 postgres: writer process   
  123 postgres: wal writer process   
  124 postgres: autovacuum launcher process   
  125 postgres: stats collector process

您可以将其放入Dockerfile以使其可重用.
