CentOS7下安装PostgreSQL12

使用yum命令添加PostgreSQL软件源

yum install https://download.postgresql.org/pub/repos/yum/reporpms/EL-7-x86_64/pgdg-redhat-repo-latest.noarch.rpm

使用yum命令安装PostgreSQL

yum install postgresql12
yum install postgresql12-server
yum install postgresql12-contrib

初始化数据库

/usr/pgsql-12/bin/postgresql-12-setup initdb

配置开机启动与启动

systemctl enable postgresql-12
systemctl start postgresql-12

切换到postgres用户。然后执行修改用户密码SQL语句。其中“postgres”为要修改密码的用户,“123456”为用户的密码

su - postgres
psql -c "alter user postgres with password '123456'"

配置远程访问

vi /var/lib/pgsql/12/data/postgresql.conf
将“#listen_addresses = ‘localhost’”改为“listen_addresses = ‘*’

打开并编辑文件“/var/lib/pgsql/12/data/pg_hba.conf”。在文件的末尾添加“host all all 0.0.0.0/0 md5”

重启服务

systemctl  restart postgresql-12
