brew install [email protected]がソケット経歴でローカルのMySQLサーバーに接続できない

私はbrew install [email protected]を実行したので、Mac OS High SierraにMySQL 5.7をインストールする必要がありました。

brew services listを実行すると、[email protected] started admin /Users/admin/Library/LaunchAgents/[email protected]が表示されます。

ps -A | grep *mysql*の出力:

66836 ttys002    0:00.01 grep *mysql*

find / -name *mysql*の出力は this Gist に含まれています。

これを直すために私はこれを実行しました:

ln -sfv /usr/local/opt/[email protected]/*.plist ~/Library/LaunchAgents
launchctl load ~/Library/LaunchAgents/[email protected]

それから私はこれを.bash_profileに追加してリロードしました:

export MYSQL_PATH=/usr/local/Cellar/[email protected]/5.7.22
export PATH=$PATH:$MYSQL_PATH/bin

ただし、mysql -urootと入力するとこのエラーが発生します。

ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2)

これは単にbrew install mysqlを実行したときには起こりませんでしたが、もちろん間違ったバージョン番号になります。

mysqldを実行すると、この出力が得られます。

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.
key_buffer_size=8388608
read_buffer_size=131072
max_used_connections=0
max_threads=151
thread_count=0
connection_count=0
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 68220 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

おそらく、他のmysqlインストールからいくつかのディレクトリが残っていて、それらは削除されていません。

私は次のようにしてこれを解決しました:

最初にmysqlをアンインストールする

brew uninstall [email protected]

削除されなかったフォルダ/ファイルを削除します

rm -rf /usr/local/var/mysql
rm /usr/local/etc/my.cnf

Mysqlを再インストールしてリンクする

brew install [email protected]
brew link --force [email protected]

サービスを有効にして開始する

brew services start [email protected]
