5、添加用户配置环境变量
# useradd postgres -m # passwd postgres # su - postgres $ vi ~/.profile export PGPORT=8899 export PGDATA=/home/postgres/pgsql12.1/pg_root export LANG=en_US.utf8 export PGHOME=/opt/pgsql12.1/ export LD_LIBRARY_PATH=$PGHOME/lib:/lib64:/usr/lib64:/usr/local/lib64:/lib:/usr/lib:/usr/local/lib:$LD_LIBRARY_PATH export DATE=`date +"%Y%m%d%H%M"` export PATH=$PGHOME/bin:$PATH:. export MANPATH=$PGHOME/share/man:$MANPATH export PGUSER=postgres export PGHOST=$PGDATA alias rm='rm -i' alias ll='ls -lh' export PGDATABASE=center $ exit # reboot 或者 source ~/.profile # usermod -s /bin/bash postgres # su - postgres $ mkdir -p /home/postgres/pgsql12.1/pg_root $ initdb -D $PGDATA -E UTF8 --locale=C -U postgres -W # 这里需要输入两次密码
6、修改内核参数
$ su - root # vi /etc/sysctl.conf kernel.shmmax = 68719476736 kernel.shmall = 4294967296 kernel.shmmni = 4096 kernel.sem = 50100 64128000 50100 1280 fs.file-max = 7672460 net.ipv4.ip_local_port_range = 9000 65000 net.core.rmem_default = 1048576 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576 # sysctl -p # vi /etc/security/limits.conf * soft nofile 131072 * hard nofile 131072 * soft nproc 131072 * hard nproc 131072 * soft core unlimited * hard core unlimited * soft memlock 50000000 * hard memlock 50000000

# sudo ufw status verbose Status: active Logging: on (low) Default: deny (incoming), allow (outgoing), disabled (routed) New profiles: skip # sudo ufw disable Firewall stopped and disabled on system startup # sudo ufw status verbose Status: inactive
8、配置pg_hba.conf
$ cd $PGDATA $ vi pg_hba.conf 添加允许访问的IP段 host all all 192.168.0.0/16 md5 host all all 10.10.0.0/16 md5
9、配置 postgresql.conf
listen_addresses = '0.0.0.0' port = 7788 max_connections = 100 superuser_reserved_connections = 13 unix_socket_directories = '.' unix_socket_permissions = 0700 tcp_keepalives_idle = 60 tcp_keepalives_interval = 10 tcp_keepalives_count = 10 shared_buffers = 128MB vacuum_cost_delay = 10 bgwriter_delay = 10ms wal_writer_delay = 10ms log_destination = 'csvlog' logging_collector = on log_directory = 'pg_log' log_filename = 'postgresql-%Y-%m-%d_%H%M%S.log' log_file_mode = 0600 log_truncate_on_rotation = on log_rotation_age = 1d log_rotation_size = 10MB log_checkpoints = on log_connections = on log_disconnections = on log_error_verbosity = verbose log_timezone = 'Asia/Shanghai'
10、启动数据库
$ pg_ctl start [-d $PGDATA]
11、进入数据库
$ psql -h 127.0.0.1 -p 7788 -U postgres postgres
12、停止数据库
$ pg_ctl stop [-m fast|smart|immediate][-d $PGDATA]
