  • centos下mysql中table大小写改为不敏感

    项目由win系统部署到linux系统下,启动项目报错如下:

    Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'jeecg-boot.QRTZ_LOCKS' doesn't exist

            at org.quartz.impl.jdbcjobstore.StdRowLockSemaphore.executeSQL(StdRowLockSemaphore.java:96)
    

    其实一看提示信息就感觉差不多了,QRTZ_LOCKS是大写,但是数据库中是小写qrtz_locks。 其实就是linux 表名不区分大小写,解决办法。

    vi /etc/my.cnf 
    在 [mysqld] 节中添加: 
    lower_case_table_names=1
    

    然后重启MySQL(在根目录下运行命令即可):

    systemctl restart mysql
    

    就可以了。
