PostgreSQL编译安装

安装依赖

yum install -y gcc readline-devel openssl-devel zlib-devel

下载解压

wget https://ftp.postgresql.org/pub/source/v13.0/postgresql-13.0.tar.gz
tar -zxf postgresql-13.0.tar.gz
cd postgresql-13.0

安装

./configure --prefix=/usr/local/pgsql
make && make install

添加用户并授权

useradd postgres
passwd postgres
mkdir -p /data/pgsql/data
mkdir -p /data/pgsql/log
touch /data/pgsql/log/pgsql.log
chown -R postgres:postgres /data/pgsql

添加环境变量

vi /etc/profile

#postgresql
export PGHOME=/data/pgsql
export PGBASE=/usr/local/pgsql
export PATH=$PATH:$PGBASE/bin

source /etc/profile

初始化数据

切换到postgres执行
su - postgres
initdb -D /data/pgsql/data

修改pg_hba.conf文件

vi /data/pgsql/data/pg_hba.conf

0.0.0.0/0，表示信任来自所有id连接的客户端，加密方式改为md5

修改postgresql.conf配置文件

vi /data/pgsql/data/postgresql.conf

将localhost改为*，表示监听所有的网络连接。其他的参数保持默认即可。
