这边因为项目上线,在 MySQL 5.5 以及 5.7 中测试过去了,但是线上 MySQL 版本为 5.6 执行失败
Incorrect integer value: '' for column 'id' at row 1 [closed]
原因是 sql_mode 设置了,但在 my.cnf 中配置时取消 sql_mode 发现仍未解决该问题。无奈只能临时 SET global sql_mode = ''
解决问题,随后用最笨的检查方式检索整个硬盘上的 my.cnf
文件,发现其中一个配置文件内容为
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
[mysqld]
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = .....
# port = .....
# server_id = .....
# socket = .....
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
将 sql_mode
行注释后解决该问题。
该my.cnf
位于 /usr/local/mysql/my.cnf
而实际使用的是 /etc/my.cnf
。
新手请教 MySQL 是可以加载多个 my.cnf 配置文件的吗?如何检查 MySQL 的配置文件加载都有哪些?以及加载顺序呢?
