一、安装和启用EPEL、CRB、PostgreSQL仓库
dnf -y install epel-release dnf -y install https://download.postgresql.org/pub/repos/yum/reporpms/EL-9-x86_64/pgdg-redhat-repo-latest.noarch.rpm dnf -y config-manager --set-enabled crb
二、禁用系统自带PostgreSQL模块
dnf -qy module disable postgresql
三、查找PostgreSQL和PostGIS的版本情况
# dnf list postgresql12 --showduplicates | sort -r postgresql12.x86_64 12.9-6PGDG.rhel9 pgdg12 postgresql12.x86_64 12.9-2PGDG.rhel9 pgdg12 postgresql12.x86_64 12.9-2PGDG.rhel9 @pgdg12 postgresql12.x86_64 12.8-3PGDG.rhel9 pgdg12 postgresql12.x86_64 12.13-1PGDG.rhel9 pgdg12 postgresql12.x86_64 12.12-1PGDG.rhel9 pgdg12 postgresql12.x86_64 12.11-1PGDG.rhel9 pgdg12 postgresql12.x86_64 12.10-1PGDG.rhel9 pgdg12 # dnf list postgis30_12 --showduplicates | sort -r postgis30_12.x86_64 3.0.7-1.rhel9 pgdg12 postgis30_12.x86_64 3.0.6-1.rhel9 pgdg12 postgis30_12.x86_64 3.0.5-1.rhel9 pgdg12 postgis30_12.x86_64 3.0.5-1.rhel9 @pgdg12
四、安装PostgreSQL和PostGIS的需求版本
dnf -y install postgresql12-12.9-2PGDG.rhel9 postgresql12-libs-12.9-2PGDG.rhel9 postgresql12-server-12.9-2PGDG.rhel9 postgresql12-contrib-12.9-2PGDG.rhel9 postgis30_12-3.0.5-1.rhel9
五、初始化数据库
/usr/pgsql-12/bin/postgresql-12-setup initdb
六、配置文件修改
# vim /var/lib/pgsql/12/data/postgresql.conf listen_addresses = '*' # /var/lib/pgsql/12/data/pg_hba.conf host all all 0.0.0.0/0 md5 #最后一行增加
七、启动服务
systemctl enable --now postgresql-12
八、其他配置
# 切换到postgres用户 su - postgres # 创建用户 createuser cent # 配置用户密码 psql -c "alter user cent with password 'password';" # 创建数据库 createdb testdb -O cent # 验证用户连接数据库权限 psql -h 10.10.10.10 -d testdb -U cent # 查看用户 psql -c "select usename from pg_user;" # 查看数据库 psql -l # 还原备份数据 psql -d testdb -U postgres -f dump.sql # 连接数据库 psql testdb testdb=> \du #查看用户角色 testdb=> \dt #查看数据库表 testdb=> \q #退出 # 删除数据库 dropdb testdb
