錢淋西2年前10瀏覽0評論

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:
