centos换源+安装postgresql

http://mirror.nsc.liu.se/centos-store/8.2.2004/isos/x86_64/ 镜像安装网站

https://mirrors.edge.kernel.org/pub/software/scm/git/git-2.24.0.tar.xz git版本网站

1 更换阿里源

[ivanlee@localhost Desktop]$ cd /etc/yum.repos.d
[ivanlee@localhost yum.repos.d]$ ls
CentOS-AppStream.repo   CentOS-Devel.repo      CentOS-PowerTools.repo
CentOS-Base.repo        CentOS-Extras.repo     CentOS-Sources.repo
CentOS-centosplus.repo  CentOS-fasttrack.repo  CentOS-Vault.repo
CentOS-CR.repo          CentOS-HA.repo
CentOS-Debuginfo.repo   CentOS-Media.repo

首先全部删除源的所有文件,遇到所有的询问都是y

[root@localhost yum.repos.d]# rm *.repo 

rm: remove regular file 'CentOS-AppStream.repo'? y
​			·························

安装新的阿里源

[root@localhost yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo

如果遇到无法解析网址的情况:

[root@localhost yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo
--2022-05-07 15:42:13--  https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo
Resolving mirrors.aliyun.com (mirrors.aliyun.com)... failed: Name or service not known.
wget: unable to resolve host address 'mirrors.aliyun.com'

那就对本地/etc/resolv.conf文件进行修改,添加如下字段

nameserver 8.8.8.8
nameserver 8.8.4.4

再继续就好了

手动安装pgsql

注意:程序安装目录是"/usr/pgsql-12",程序运行目录是"/var/run/postgresql",程序运行用户和组是"postgres:postgres","postgres"用户和组安装时默认创建。

pgsql的配置

1 设置数据库默认的数据存储目录

数据库实例的默认存储目录是/var/lib/pgsql/12/data/,/var是一个系统目录,不适合存放大量的业务数据,因此要在初始化数据库实例之前创建一个存储目录

mkdir -p /data/pgsql12-data:因为创建了多级目录,所以需要-p

[root@localhost /]# mkdir -p /data/pgsql12-data
[root@localhost /]# ls
bin  boot  data  dev  etc  home  lib  lib64  lost+found  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var
[root@localhost /]# cd data
[root@localhost data]# ll
total 4
drwxr-xr-x. 2 root root 4096 Mar 22 14:27 pgsql12-data

设置数据存储目录的所有者用户和组为postgres:postgres,postgres用户和组在安装PostgreSQL12时已创建

[root@localhost data]# chown postgres:postgres /data/pgsql12-data

修改postgreSQL12开机启动服务配置文件,设置为新的数据存储目录

[root@localhost data]# vim /usr/lib/systemd/system/postgresql-12.service <服务配置文件路径!>

将其中的enviroment变量注释掉,改为新的(vim如果卡死,按键ctrl+q)

file

2 初始化数据库实例

进入程序安装目录下的bin目录下,执行postgresql-12-setup initdb命令。

[root@localhost data]# cd /usr/pgsql-12/bin
[root@localhost bin]# ./postgresql-12-setup initdb
Initializing database ... OK

3 启动数据库实例服务,并设置为开机自动启动

[root@localhost bin]# systemctl enable postgresql-12.service
Created symlink /etc/systemd/system/multi-user.target.wants/postgresql-12.service → /usr/lib/systemd/system/postgresql-12.service.
[root@localhost bin]# systemctl start postgresql-12.service

4 设置数据库实例超级管理员账户postgres的口令

postgreSQL12安装完成后postgres的默认口令为空,为空时无法使用该用户登录数据库。

[root@localhost bin]# passwd postgres
Changing password for user postgres.
New password: prs@2018
Retype new password: prs@2018
passwd: all authentication tokens updated successfully.
[root@localhost bin]# su postgres
bash-4.4$ psql
psql (12.10)
Type "help" for help.
 
postgres=#  alter user postgres with password 'xxxxx';
ALTER ROLE
postgres=# \q
bash-4.4$ exit
exit
[root@localhost bin]# 

5 设置数据库实例的远程访问策略

postgreSQL12安装完成后默认只允许本地访问

设置数据库实例访问策略,可以设置多个由主机类型、数据库、用户、IP地址组成的策略。

​ 在文件的"# IPv4 local connections"策略中追加一条“允许全部用户,通过全部网络地址访问全部数据库”的策略并保存,策略定义如 下:

vim /data/pgsql12-data/pg_hba.conf  "配置文件conf"
image-20220507152653413

file

设置数据库实例的监听端口

监听地址:*默认是全部地址,默认是localhost ||监听端口:默认是5432

​ vim /data/pgsql12-data/postgresql.conf

file

设置防火墙端口

​ centOS8默认安装firewall防火墙,允许5432端口(PostgreSQL默认端口)访问服务器。

[root@localhost bin]# firewall-cmd --zone=public --add-port=5432/tcp --permanent
success
[root@localhost bin]# firewall-cmd --reload
success

重新启动数据库服务实例

systemctl restart postgresql-12.service

数据库的运维和管理

数据库启动、停止、重启、查看状态、开机自启动、禁用开机自启动

[root@localhost bin]# systemctl start postgresql-12.service   #开启
[root@localhost bin]# systemctl stop postgresql-12.service    #停止
[root@localhost bin]# systemctl restart postgresql-12.service #重启
[root@localhost bin]# systemctl status postgresql-12.service  #查看状态
