之前安装的目录为/usr/local/develope/mysql
后来改了下目录 同时也改了MySQL文件夹名
现在为/usr/local/develope/develop/mysql5.6 同时data目录还是在的
配置文件已经修改
MySQL在安装或者启动的时候没有指定配置文件时候 默认找的配置文件/etc/my.cnf
将basedir目录和data目录修改为新的目录(注意一定要修改对 )
basedir=/usr/local/develop/mysql5.6 datadir=/usr/local/develop/mysql5.6/data
误区 修改了目录后不需要重新初始化 因为data目录是不为空的 除非删除掉data目录 重新安装
错误1：无法解析的域名
root@xxx-Pro mysql5.6 # ./scripts/mysql_install_db --user=mysql
FATAL ERROR: Neither host 'xxx.Pro.local' nor 'localhost' could be looked up with
/usr/local/develope/mysql5.6/bin/resolveip
Please configure the 'hostname' command to return a correct
hostname.
If you want to solve this at a later stage, restart this script
with the --force option
解决方法 编辑 /etc/hosts文件
127.0.0.1 localhost xxx.Pro.local
保存退出 即可
同时在mysql5.6 该目录下 运行 ./bin/resolveip localhost
IP address of localhost is 127.0.0.1
出来如下内容即为配置成功
同样还是误区 不需要重新安装 或者考虑删除 data目录 重新安装
root@xxx-Pro scripts # ./mysql_install_db --user=mysql
FATAL ERROR: Could not find ./bin/my_print_defaults
If you compiled from source, you need to run 'make install' to
copy the software into the correct location ready for operation.
If you are using a binary release, you must either be at the top
level of the extracted archive, or pass the --basedir option
pointing to that location.
解决 在scripts 目录下 ./bin/my_print_defaults 这个文件是没有的
需要在mysql5.6 安装根路径下 进行执行
错误原因 服务器在没有更新PID文件的情况下退出
root@xxx-Pro mysql5.6 # ./support-files/mysql.server start
Starting MySQL
.Warning: World-writable config file '/usr/local/develop/mysql5.6/my.cnf' is ignored
Warning: World-writable config file '/usr/local/develop/mysql5.6/my.cnf' is ignored

.. ERROR! The server quit without updating PID file (/usr/local/develop/mysql5.6/data/liangzhuangdeMacBook-Pro.local.pid).
解决办法
1.检查/etc/my.cnf MySQL配置文件的 basedir配置和datadir配置是否修改正确
basedir=/usr/local/develop/mysql5.6 datadir=/usr/local/develop/mysql5.6/data
2.如果basedir配置和datadir配置修改的正确 尝试删除 /etc/my.cnf 文件 （注意备份）然后重新启动MySQL
