我运行了centos:7.1.1503
然后yum install postgresql
。不幸的是,由于 systemd 问题,service postgresql start
即使安装后我也无法运行initscripts
:

You could try using --skip-broken to work around the problem
** Found 1 pre-existing rpmdb problem(s), 'yum check' output follows:

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。
答案1
不用管 systemd,直接运行 Postgres 就行。下面展示了如何在基础 Centos7 容器内运行 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 以使其可重复使用。

https://hub.docker.com/r/centos/postgresql-10-centos7
我在这里使用命令......
--restart="总是"
选项意味着在docker启动时始终启动。
docker run -d --name postgresql --restart="always" \ -e POSTGRESQL_USER=<你的 ID> \ -e POSTGRESQL_PASSWORD=<你的密码> \ -e POSTGRESQL_DATABASE=<你的数据库名称> \ -e POSTGRESQL_ADMIN_PASSWORD=<postgres 的密码> \ -p 5432:5432 centos/postgresql-10-centos7
试试看吧~
