MySQL是一個流行的關系數據庫管理系統,它被廣泛應用于Web開發中。如果你使用MySQL,那么你一定需要確保你的MySQL安裝成功并且能夠正常工作。下面是一些檢查MySQL安裝的方法。
1. 檢查MySQL服務是否正在運行:
$ systemctl status mysql or $ service mysql status
如果MySQL服務正在運行,你應該看到以下輸出:
mysql.service - MySQL Community Server Loaded: loaded (/usr/lib/systemd/system/mysql.service; enabled; vendor preset: enabled) Active: active (running) since Wed 2021-07-21 04:09:27 UTC; 4 weeks 1 days ago
2. 檢查MySQL是否已經安裝:
$ mysql --version
如果MySQL已成功安裝,你應該看到類似以下輸出:
mysql Ver 14.14 Distrib 5.7.34, for Linux (x86_64) using EditLine wrapper
3. 連接到MySQL并嘗試創建一個新的數據庫:
$ mysql -u root -p mysql>CREATE DATABASE testdb; mysql>quit;
如果你成功連接到MySQL并創建了testdb數據庫,你應該看到以下輸出:
Query OK, 1 row affected (0.00 sec)
4. 檢查是否可以使用創建的數據庫:
$ mysql -u root -p testdb
如果你成功連接到testdb數據庫,你應該看到以下輸出:
Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Welcome to the MySQL monitor. Commands end with ; or \g.

總之,這些方法可以幫助你驗證你的MySQL安裝是否成功,并可以建立和訪問數據庫。
