命令)。/var/log/mysql/error.log
或MySQL安装目录下的 data
文件夹中)。/var/lib/mysql
)具有正确的权限和所有权。/etc/mysql/my.cnf

)是否有语法错误。以下是一个简单的Python脚本示例,用于连接已启动的MySQL服务器:
import mysql.connector
try:
connection = mysql.connector.connect(
host="localhost",
user="root",
password="your_password"
)
if connection.is_connected():
db_Info = connection.get_server_info()
print("Connected to MySQL Server version ", db_Info)
cursor = connection.cursor()
cursor.execute("select database();")
record = cursor.fetchone()
print("You're connected to database: ", record)
except mysql.connector.Error as e:
print("Error while connecting to MySQL", e)
finally:
if connection.is_connected():
cursor.close()
connection.close()
print("MySQL connection is closed")
确保将 "your_password"
替换为实际的MySQL root密码。
通过以上步骤和示例代码,你应该能够成功开启并连接到MySQL服务器。如果遇到具体问题,请根据错误信息进行排查。
