我试图让 pgbouncer 在我的独立 postgresql 服务器上工作,但是当我尝试使用 pgbouncer 端口连接到数据库时,出现超时错误。
PostgreSQL:9.1.8
pgBouncer:1.4.2
操作系统:Ubuntu 12.04.2 LTS (GNU/Linux 3.8.4-x86_64-linode31 x86_64)
这是我的conf文件:
[databases]
postgres = host=127.0.0.1 port=5432 dbname=postgres
mydb = host=127.0.0.1 port=5432 dbname=mydb
[pgbouncer]
logfile = /home/username/pg_log/pgbouncer.log
pidfile = /tmp/pgbouncer.pid
listen_addr = xxx.xxx.xxx.xxx
listen_port = 6432
unix_socket_dir = /var/run/postgresql
auth_type = md5
auth_file = /etc/pgbouncer/userlist.txt
admin_users = postgres
stats_users = stats, root
user = postgres
pool_mode = session
server_reset_query = DISCARD ALL
max_client_conn = 1000
default_pool_size = 20
log_connections = 1
log_disconnections = 1
log_pooler_errors = 1
我试图像这样测试连接:
psql -p 6432 -U postgres mydb
这是我的日志文件:

为了使 pgbouncer 工作,我还需要改变什么吗?
