问题描述
在Mac Mojave上安装mysql 5.7时遇到很多麻烦，(运行'brew install [email protected]')
Having a lot of trouble installing mysql 5.7 on Mac Mojave, (ran 'brew install [email protected]')
在初始安装时，出现消息，提示安装后未成功完成(请参见下面的消息).
on initial install, got msg saying postinstall was not completed successfully (please see msg below).
因此，删除目录/usr/local/var/mysql中的所有内容(mysql表示不为空)后，重新运行postinstall命令时，我仍然会收到相同的消息...(这似乎很令人讨厌，MySQL正在填充数据目录，然后抱怨它不为空?！)
So, after I delete everything in the directory /usr/local/var/mysql (which mysql says is not empty), I STILL get same message when re-running postinstall command ... (which is quite annoying seems MySQL is populating the data dir then complaining it is not empty?!)

尝试以root身份启动mysql会出现错误:
Trying to start mysql as root gives error:
现在试图追随StackOverflow帖子的日子越来越长，，没有一个正在工作...
Banging head against wall for days now trying to follow StackOverflow posts MySql server startup error 'The server quit without updating PID file ', none of which is working ...
我的my.cnf:
[mysqld]
# Only allow connections from localhost
#bind-address = 127.0.0.1
#SO posts said to comment out the above ...
pid-file = /var/run/mysqld/mysqld.pid #Checked, this folder + file exists, with write permissions
推荐答案
尝试使用远离mysql目录的数据目录，即，如果mysql位于/usr/local/mysql中，则将数据目录用作/var/data. /p>
Try using a data dir away from the mysql directory i.e if mysql is in /usr/local/mysql, use the data dir as /var/data.
root@photon [ /var ]# /usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --datadir=/var/data
