centos換源+安裝postgresql

http://mirror.nsc.liu.se/centos-store/8.2.2004/isos/x86_64/ 鏡像安裝網站

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

1 更換阿裡源

[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

首先全部刪除源的所有文件，遇到所有的詢問都是y

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

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

​			·························

安裝新的阿裡源

[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

如果遇到無法解析網址的情況：

[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'

那就對本地/etc/resolv.conf文件進行修改，添加如下欄位

nameserver 8.8.8.8
nameserver 8.8.4.4

再繼續就好了

手動安裝pgsql

註意：程式安裝目錄是"/usr/pgsql-12"，程式運行目錄是"/var/run/postgresql"，程式運行用戶和組是"postgres:postgres"，"postgres"用戶和組安裝時預設創建。

pgsql的配置

1 設置資料庫預設的數據存儲目錄

資料庫實例的預設存儲目錄是/var/lib/pgsql/12/data/,/var是一個系統目錄，不適合存放大量的業務數據，因此要在初始化資料庫實例之前創建一個存儲目錄

mkdir -p /data/pgsql12-data：因為創建了多級目錄，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

設置數據存儲目錄的所有者用戶和組為postgres:postgres，postgres用戶和組在安裝PostgreSQL12時已創建

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

修改postgreSQL12開機啟動服務配置文件，設置為新的數據存儲目錄

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

將其中的enviroment變數註釋掉，改為新的（vim如果卡死，按鍵ctrl+q）

image-20220507152835299

2 初始化資料庫實例

進入程式安裝目錄下的bin目錄下，執行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 啟動資料庫實例服務，並設置為開機自動啟動

[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 設置資料庫實例超級管理員賬戶postgres的口令

postgreSQL12安裝完成後postgres的預設口令為空，為空時無法使用該用戶登錄資料庫。

[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 設置資料庫實例的遠程訪問策略

postgreSQL12安裝完成後預設只允許本地訪問

  1. 設置資料庫實例訪問策略，可以設置多個由主機類型、資料庫、用戶、IP地址組成的策略。

​ 在文件的"# IPv4 local connections"策略中追加一條“允許全部用戶，通過全部網路地址訪問全部資料庫”的策略並保存，策略定義如 下：

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

image-20220507152653413

  1. 設置資料庫實例的監聽埠

    監聽地址：*預設是全部地址，預設是localhost ｜｜監聽埠：預設是5432

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

image-20220507152714617

  1. 設置防火牆埠

​ centOS8預設安裝firewall防火牆，允許5432埠（PostgreSQL預設埠）訪問伺服器。

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

重新啟動資料庫服務實例

systemctl restart postgresql-12.service

資料庫的運維和管理

  1. 資料庫啟動、停止、重啟、查看狀態、開機自啟動、禁用開機自啟動

    [root@localhost bin]# systemctl start postgresql-12.service   #開啟
[root@localhost bin]# systemctl stop postgresql-12.service    #停止
[root@localhost bin]# systemctl restart postgresql-12.service #重啟
[root@localhost bin]# systemctl status postgresql-12.service  #查看狀態
