Centos7安装PostgresSQL

• 更新系统

sudo yum update -y

• 添加PostgreSQL Yum存储库

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

• 安装PostgreSQL Server和客户端软件包

sudo yum install -y postgresql13-server postgresql13

• 查看安裝是否完成

sudo rpm -qi postgresql13-server

• 初始化数据库

sudo /usr/pgsql-13/bin/postgresql-13-setup initdb
sudo systemctl enable postgresql-13
sudo systemctl start postgresql-13
# 停止数据库
sudo systemctl stop postgresql-13

• 数据库初始化完成后，可以通过修改数据文件目录的postgresql.conf配置文件来达到设置postgresql侦听端口的目的

vim /var/lib/pgsql/13/data/postgresql.conf

listen_addresses = '*'    

• 允许远程访问

vim /var/lib/pgsql/13/data/pg_hba.conf

修改postgres密码

su postgres 

psql 

alter user postgres with password 'postgres';

修改后的内容如下：

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     trust
# IPv4 local connections:
host    all             all             127.0.0.1/32            trust
host    all             all             0.0.0.0/0                 md5
# IPv6 local connections:
host    all             all             ::1/128                 trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
local   replication     all                                     trust
host    replication     all             127.0.0.1/32            trust
host    replication     all             ::1/128                 trust

• 修改用户密码

  #登陆postgresql
  sudo -u postgres psql
  
  #修改i登陆postgresql密码
  alter user postgres with password 'postgres';

• 开放防火墙

firewall-cmd --zone=public --add-port=5432/tcp --permanent
firewall-cmd --reload
# 查看是否开放
firewall-cmd --query-port=5432/tcp
