我运行centos:7.1.1503然后yum install postgresql 。 不幸的是，由于系统问题，即使安装了initscripts之后，我仍然无法运行service postgresql start ：

我现在能做什么？ 我正在考虑从头开始构build，并以这种方式工作。
不要打扰systemd，直接运行Postgres。 以下显示了如何让Postgres在一个基本的Centos7容器内运行：
$ 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
你可以把它放到一个Dockerfile中，使它可以重用。
