centos7離線安裝postgresql13

1. 在一台可以聯網的centos上安裝postgresql源

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

2. 使用yumdownloader下載安裝包

yumdownloader --resolve postgresql13-server

3. 上傳rpm包到安裝的centos服務器上

-rw-rw-rw- 1 root root 1490812 Sep 27 09:45 postgresql13-13.4-1PGDG.rhel7.x86_64.rpm
-rw-rw-rw- 1 root root  390420 Sep 27 09:45 postgresql13-libs-13.4-1PGDG.rhel7.x86_64.rpm
-rw-rw-rw- 1 root root 5654980 Sep 27 09:45 postgresql13-server-13.4-1PGDG.rhel7.x86_64.rpm

4. 批量安裝rpm包

rpm -ivh postgresql13-13.4-1PGDG.rhel7.x86_64.rpm postgresql13-libs-13.4-1PGDG.rhel7.x86_64.rpm postgresql13-server-13.4-1PGDG.rhel7.x86_64.rpm

報錯了，缺少依賴libicu

warning: postgresql13-13.4-1PGDG.rhel7.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID 442df0f8: NOKEY
error: Failed dependencies:
        libicu is needed by postgresql13-13.4-1PGDG.rhel7.x86_64
        libicui18n.so.50()(64bit) is needed by postgresql13-server-13.4-1PGDG.rhel7.x86_64
        libicuuc.so.50()(64bit) is needed by postgresql13-server-13.4-1PGDG.rhel7.x86_64

5. 使用yumdownloader下載libicu

yumdownloader --resolve libicu

-rw-r--r-- 1 root root 7250656 Mar 25  2020 libicu-50.2-4.el7_7.i686.rpm
-rw-r--r-- 1 root root 7202728 Mar 25  2020 libicu-50.2-4.el7_7.x86_64.rpm
-rw-r--r-- 1 root root 1490812 Aug 12 18:07 postgresql13-13.4-1PGDG.rhel7.x86_64.rpm
-rw-r--r-- 1 root root  390420 Aug 12 18:07 postgresql13-libs-13.4-1PGDG.rhel7.x86_64.rpm
-rw-r--r-- 1 root root 5654980 Aug 12 18:07 postgresql13-server-13.4-1PGDG.rhel7.x86_64.rpm

刪除libicu-50.2-4.el7_7.i686.rpm（32位安裝包）
6. 重新上傳到需要安裝的服務器，執行安裝命令

rpm -ivh libicu-50.2-4.el7_7.x86_64.rpm postgresql13-13.4-1PGDG.rhel7.x86_64.rpm postgresql13-libs-13.4-1PGDG.rhel7.x86_64.rpm postgresql13-server-13.4-1PGDG.rhel7.x86_64.rpm

7. 安裝成功后初始化數據庫

/usr/pgsql-13/bin/postgresql-13-setup initdb

8. 開機啟動postgresql數據庫

systemctl enable postgresql-13

9. 啟動postgresql數據庫服務

systemctl start postgresql-13

10. 創建用戶和數據庫，使用postgres用戶登錄（PostgresSQL安裝后會自動創建postgres用戶，無密碼）

su postgres

11. 登錄postgresql數據庫

psql

12. 創建用戶和數據庫並授權

create user ycloans with password 'ycloans';            // 創建用戶
create database sonarqube owner ycloans;                 // 創建數據庫
grant all privileges on database sonarqube to ycloans;   // 授權

\q 退出命令模式
13. 開啟遠程訪問，修改/var/lib/pgsql/13/data/postgresql.conf文件，取消 listen_addresses 的注釋，將參數值改為“*”

14. 修改/var/lib/pgsql/13/data/pg_hba.conf文件，增加下圖紅框部分內容
    
15. 切換到root用戶，重啟postgresql服務

systemctl restart postgresql-13
