pgbouncer版本为1.7.2
psql版本为9.5.6
我尝试在PgBouncer中使用auth_hba_file（/var/lib/pgsql/9.5/data/pg_hba.conf）。
pgbouncer.ini配置文件如下：
postgres = host=localhost port=5432 dbname=postgres user=postgres
test = host=localhost port=5432 dbname=test user=test
[pgbouncer]
logfile = /var/log/pgbouncer/pgbouncer.log
pidfile = /var/run/pgbouncer/pgbouncer.pid
listen_addr = *
listen_port = 6432
auth_type = hba
auth_hba_file = /var/lib/pgsql/9.5/data/pg_hba.conf
admin_users = postgres
stats_users = stats, postgres
pool_mode = session
server_reset_query = DISCARD ALL
max_client_conn = 100
default_pool_size = 20
使用 cat 命令读取 pg_hba.conf 文件，过滤掉包含 "#" 的行和空行
local all all trust
host all all 127.0.0.1/32 trust
host all all ::1/128 trust
host test test 10.255.4.0/24 md5
psql -h 10.233.4.16 -p 5432 -U test
Password for user test:
psql (9.5.6)
Type "help" for help.
test=> \q
psql -h 10.233.4.16 -p 6432 -U test
psql: ERROR: No such user: test
使用 tail -fn10 /var/log/pgbouncer/pgbouncer.log 命令来实时监控 Pgbouncer 日志的最后 10 行。
LOG C-0x78f7e0: (nodb)/(nouser)@10.255.4.245:8963 closing because: No such user: test (age=0)
WARNING C-0x78f7e0: (nodb)/(nouser)@10.255.4.245:8963 Pooler Error: No such user: test
LOG C-0x78f7e0: (nodb)/(nouser)@10.255.4.245:8963 login failed: db=test user=test
但是我无法使用pg_hba.conf连接到postgresql（使用PgBouncer）
有人可以帮助吗？您是否有使用auth_hba_file的示例。 谢谢。
我更改了配置：
[root@dev-metrics2 pgbouncer]＃cat pgbouncer.ini | grep -v";"| grep -v“^ $”| grep -v“＃”
[databases]
postgres = host=localhost port=5432 dbname=postgres user=postgres
test = host=localhost port=5432 dbname=test auth_user=test
[pgbouncer]
logfile = /var/log/pgbouncer/pgbouncer.log
pidfile = /var/run/pgbouncer/pgbouncer.pid
listen_addr = *
listen_port = 6432
auth_query = SELECT usename, passwd FROM pg_shadow WHERE usename=$1
admin_users = postgres
stats_users = stats, postgres
pool_mode = session
server_reset_query = DISCARD ALL
max_client_conn = 100
default_pool_size = 20
删除和创建用户和数据库
[local]:5432 postgres@postgres # DROP DATABASE test;
DROP DATABASE
[local]:5432 postgres@postgres # DROP USER test ;
DROP ROLE
[local]:5432 postgres@postgres # CREATE USER test with password 'test';

PGPASSWORD=test psql -h 10.233.4.16 -p 6432 -U test
Password for user test:

工作配置：
cat pgbouncer.ini | grep -v ";" | grep -v "^$" | grep -v "#"
[databases]
*= port=5432 auth_user=postgres
[pgbouncer]
logfile = /var/log/pgbouncer/pgbouncer.log
pidfile = /var/run/pgbouncer/pgbouncer.pid
listen_addr = *
listen_port = 6432
auth_query = SELECT usename, passwd FROM pg_shadow WHERE usename=$1
admin_users = postgres
stats_users = stats, postgres
pool_mode = session
server_reset_query = DISCARD ALL
max_client_conn = 100
default_pool_size = 20
auth_file指定的文件中，如果不在（必须是这种情况），则添加，例如"test" "md564b76e462e88c4fa6898960d067845b8"- 您可以从select passwd from pg_shadow where usename = 'test';中找到哈希值。 - Vao Tsun
