MySQL 重裝

因爲以前第一次裝MySQL,默認的datadir在啓動盤中,我想要將datadir移動到更大的存儲盤中。無奈網上的各類文章的方法在我這裏老是不work。我決定從新用homebrew來裝一遍MySQL。mysql

但是因爲以前各類嘗試致使的亂七八糟的操做過多,以致於我連以前裝MySQL的方法也用不了了。無奈之下,只得一步步摸索重來。sql

1. 完全清除MySQLspa

以前混亂操做過多,因而只得相對完全地把以前的痕跡清除code

ps -ax | grep mysql
# stop and kill any MySQL processes

# rm files and directories
sudo rm /usr/local/mysql
sudo rm -rf /usr/local/var/mysql
sudo rm -rf /usr/local/mysql*
sudo rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

# edit /etc/hostconfig and remove the line MYSQLCOM=-YES-

# rm files and directories
rm -rf ~/Library/PreferencePanes/My*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
sudo rm -rf /private/var/db/receipts/*mysql*

# try to run mysql, it shouldn't work

注意,除此以外, 還要將如下文件或文件夾好好查看及清理server

/tmp/  #這裏有mysql.sock 以及 mysql.sock.lock 文件,我以前不當心把lock文件的user改爲_mysql了,致使後面一直不work。所以,最好把這兩個文件都刪掉
/etc/my.cnf #這個文件當時建立之後就沒扔,致使後來重裝總出問題,也把這個文件刪掉

2. brew installblog

接下來,就能夠使用brew來安裝了進程

brew doctor # and fix any errors
brew uninstall mysql
brew cleanup
brew update
brew install mysql
unset TMPDIR
mysql_install_db --verbose --user=·whoami· --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql #5.7 沒有 --tmpdir選項
mysql.server start

 

接下來應該就沒有問題了。homebrew

若是還有問題,多是你以前已經成功登錄,可是忘了ip

lsof -i TCP:3306 # 找到正在佔用ip的process id

kill [pid] # 終止該進程

mysql.server start
