PgBouncer和auth到PostgreSQL

Question

pgbouncer版本1.7.2

psql(9.5.6)

我尝试在PgBouncer中使用auth_hba_file(/var/lib/pgsql/9.5/data/pg_hba.conf).

配置pgbouncer.ini

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

cat pg_hba.conf | grep -v"#"| grep -v"^ $"

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测试

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

tail -fn10 /var/log/pgbouncer/pgbouncer.log

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

但我无法使用pg_hba.conf连接到postgresql(使用PgBouncer)

有人可以帮忙吗？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

删除并创建用户和数据库

[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';
CREATE ROLE
[local]:5432 postgres@postgres # CREATE DATABASE test with owner test;
CREATE DATABASE

PGPASSWORD = test psql -h 10.233.4.16 -p 6432 -U test

Password for user test:
psql: ERROR:  Auth failed

tail -fn1 /var/log/pgbouncer/pgbouncer.log

WARNING C-0x17b57a0: test/test@10.255.4.245:3070 Pooler Error: Auth failed

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

尝试放置空间

*= port=5432 auth_user=postgres  # old string
* = port=5432 auth_user=postgres # new string
