postgresql 数据库小版本更新
记录一次pg小版本更新
文章目录
前言
因为最近漏扫发现好多漏洞，需要升级pg数据库的版本用以解决漏洞问题，有些数据库不能升级大版本，只能升级小版本，网上全是讲的编译安装的，我在这里说说rpm安装如何升级。
一.下载最新的pg版本 pg11（11.18）
- 官网下载地址：
sudo yum install -y https://download.postgresql.org/pub/repos/yum/reporpms/EL-7-x86_64/pgdg-redhat-repo-latest.noarch.rpm
官网直接下载
sudo yum install -y https://download.postgresql.org/pub/repos/yum/reporpms/EL-7-x86_64/pgdg-redhat-repo-latest.noarch.rpm
安装
sudo yum install -y postgresql11-server
- 自己下载安装包及依赖
需要下载4个对应版本的rpm包。
下载地址：
https://download.postgresql.org/pub/repos/yum/11/redhat/rhel-7-x86_64/
已下载好的文件地址：pg11.18的资源
https://download.csdn.net/download/yang_z_1/87432521
把下载包放到一个目录下，上传到所需的Linux服务器
在文件目录下执行
yum localinstall *.rpm -y
[root@hrmw-template pg11.18]# yum localinstall *.rpm -y

二 pg11.5 升级 pg11.18过程
1. 查看当前数据库版本：
2. 关闭pg11.5数据库
3. 安装pg11.18
yum localinstall *.rpm -y
这步在上面已经做过了。
4.修改 配置文件
使用root用户修改 /usr/lib/systemd/system/postgresql-11.service 文件，将其中的PGDATA修改为新的数据目录
vim /usr/lib/systemd/system/postgresql-11.service
把Environment=PGDATA=修改你pg11.5的安装目录；
修改前：
修改后：
5. 重新加载配置文件
systemctl daemon-reload
6. 启动数据库
7. 查看数据库版本
