Question

 postgresql 种怎么在一台linux里面创建多个实例

Answer 1

Create the clusters

$ initdb -D /path/to/datadb1
$ initdb -D /path/to/datadb2
Run the instances

$ pg_ctl -D /path/to/datadb1 -o "-p 5433" -l /path/to/logdb1 start
$ pg_ctl -D /path/to/datadb2 -o "-p 5434" -l /path/to/logdb2 start
Test streaming

Now you have two instances running on ports 5433 and 5434. Configuration files for them are in data dirs specified by initdb. Tweak them for streaming replication.
Your default installation remains untouched in port 5432.
