postgreSQL pgBouncer安装配置

 

下载地址:http://pgfoundry.org/frs/?group_id=1000258&release_id=1981

1.安装步骤:

$ ./configure --prefix=/usr/local --with-libevent=libevent-prefix

$ make

$ make install

如果没有libevent,那么http://monkey.org/~provos/libevent/下载

Libevent安装:

$ ./configure && make

$ make verify

# make install 注意安装时用root用户

tail -1f config.log

configure: exit 0 0说明安装成功,1为失败

2.创建配置文件:

Mkdir –p $PGDATA/pgbouncer

postgres@readerlogdb-> more config.ini

[databases]

testdb = host=127.0.0.1 port=1931 dbname=testdb user=testuser password=testuser

[pgbouncer]

listen_port = 1688

listen_addr = 127.0.0.1

auth_type = md5

auth_file = /opt/pgdata/pg_root/pgbouncer/user.txt

logfile = /opt/pgdata/pg_root/pgbouncer/pgbouncer.log

pidfile = /opt/pgdata/pg_root/pgbouncer/pgbouncer.pid

pool_mode = Transaction

admin_users = pgbouncer_admin

stats_users = pgbouncer_guest

3.添加用户信息

more user.txt

"testuser" "testuser"

"pgbouncer_admin" "pgbouncer_admin"

4.启动pgbouncer

pgbouncer -d /opt/pgdata/pg_root/pgbouncer/config.ini

5.测试连接

psql -h 127.0.0.1 -p 1688 -d testdb -U testuser #testuser用户连接testdb

psql -h 127.0.0.1 -p 1688 -d pgbouncer -U pgbouncer_admin #以pgbouncer管理用户进入本身的数据库pgbouncer

6.查看相关信息

pgbouncer=# show help;

NOTICE: Console usage

DETAIL:

SHOW HELP|CONFIG|DATABASES|POOLS|CLIENTS|SERVERS|VERSION

SHOW STATS|FDS|SOCKETS|ACTIVE_SOCKETS|LISTS|MEM

SHOW DNS_HOSTS|DNS_ZONES

SET key = arg

RELOAD

PAUSE []

RESUME []

KILL

SUSPEND

SHUTDOWN

Show config; #查看相关配置

Show stats;

Show lists;#查看连接相关信息,如,数据库个数,空闲连接数等等

Show pools;#查看池中连接信息

Show databases;#查看相关数据库

Show clients; #查看连接数

如果修改了配置文件,那么需要reload重新加载

pgbouncer=# reload;

RELOAD

连接方式有三种,之前介绍过,种类不再详述,以上 一些参数的介绍,在源安装包里doc目录下有详细说明和举例。
