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:

28396 LOG listening on xxx.xxx.xxx.xxx:6432

为了使 pgbouncer 工作,我还需要改变什么吗?

改变

listen_addresses = 'private_ip'

listen_addresses = '*'

postgresql.conf文件中。

看起来您正在尝试使用 Unix 套接字进行连接。根据您的 Postgres 安装,套接字可能是在 /tmp 而不是 /var/run/postgres 中创建的。我遇到了同样的问题,这里已经讨论过了

尝试将 pgbouncer.ini 配置更改为:

unix_socket_dir = /tmp

您也可以尝试通过添加 -h 来连接到 localhost,如下所示:

 psql -p 6432 -h localhost -U postgres mydb

希望这可以帮助!

对我来说,问题似乎出在我在[databases]配置文件部分定义数据库时;我无法使用host=127.0.0.1or host=localhost,但我必须使用实际 IP,host=192.168.0.1. 这可能是由于 postgresqlpg_hba.conf文件配置错误,但我找不到使其与本地 IP 一起使用的方法。
