wget   //pgbouncer需要用到libevent依賴包


wget
2、安裝編譯所需的環境依賴

yum install gcc gcc-c++ make openssl-devel
3、解壓並編譯安裝

tar -xf libevent-2.1.11-stable.tar.gz


tar -xf pgbouncer-1.12.0.tar.gz
4、編譯安裝libevent

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


make -j 2


make install
5、配置環境變數

echo "export pkg_config_path=/usr/local/libevent/lib/pkgconfig" >> ~/.bashrc


cat ~/.bashrc


source ~/.bashrc
9、授權postgres使用者訪問libevent-2.1.so.7許可權

setfacl -rm u:postgres:rwx /usr/
10、建立軟連線

ln -s /usr/local/libevent/lib/libevent-2.1.so.7 /usr/lib64/libevent-2.1.so.7
11、編譯安裝pgbouncer

./configure --prefix=/usr/local/pgbouncer/


make -j 2


make install
12、建立pgbouncer.ini配置檔案

cat /etc/pgbouncer/pgbouncer.ini


[databases]


postgres = host=127.0.0.1 port=5432 dbname=postgres


[pgbouncer]


logfile = /var/log/pgbouncer/pgbouncer.log


pidfile = /var/run/pgbouncer/pgbouncer.pid


listen_addr = 10.15.150.41


listen_port = 6432


unix_socket_dir = /var/run/postgresql


auth_type = md5


auth_file = /etc/pgbouncer/userlist.txt


admin_users = postgres


ignore_startup_parameters = extra_float_digits,geqo


pool_mode = session


server_reset_query = discard all


max_client_conn = 10000


default_pool_size = 1000


reserve_pool_size = 30


reserve_pool_timeout = 5


max_db_connections = 5000


pkt_buf = 8192
13、建立使用者名稱及密碼認證檔案，確保僅postgres使用者可以訪問，許可權600

cat /etc/pgbouncer/userlist.txt


"postgres" "p2porlyz8"
14、配置開機自啟服務,由systemctl管理，建立pgbouncer.service檔案

cat /etc/systemd/system/pgbouncer.service


[unit]


description=pgbouncer connection pooling for postgresql


after=syslog.target network.target


[service]


type=forking


user=postgres


group=postgres


permissionsstartonly=true


execstartpre=-/bin/mkdir -p /var/run/pgbouncer /var/log/pgbouncer


execstartpre=/bin/chown -r postgres:postgres /var/run/pgbouncer /var/log/pgbouncer


execstart=/usr/local/pgbouncer/bin/pgbouncer -d /etc/pgbouncer/pgbouncer.ini


execreload=/bin/kill -sighup $mainpid


pidfile=/var/run/pgbouncer/pgbouncer.pid


limitnofile=100000


[install]


wantedby=multi-user.target
15、填寫可執行許可權

chmod +x /etc/systemd/system/pgbouncer.service
16、啟動服務

systemctl start pgbouncer
17、查詢啟動狀態systemctl status pgbouncer

18、加入開機啟動項

systemctl enable pgbouncer
