如何找到Mac上用HomeBrew安装的MySQL的启动命令

1. 找HomeBrew安装的包列表， 找到MySQL的formula

$ brew list
apache-spark heroku-node mysql@5.7 openssl@1.1 sbt
autoconf icu4c ncurses pkg-config scala@2.12
gdb libevent node pyenv tmux
heroku maven openjdk readline yarn

2. 查看MySQL的info

$ brew info mysql@5.7

==> Caveats
We&＃39;ve installed your MySQL database without a root password. To secure it run:mysql_secure_installationMySQL is configured to only allow connections from localhost by defaultTo connect run:mysql -urootmysql@5.7 is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.If you need to have mysql@5.7 first in your PATH run:echo &＃39;export PATH="/usr/local/opt/mysql@5.7/bin:$PATH"&＃39; >> /Users/XXXXXXXXXXXXXXX/.bash_profileFor compilers to find mysql@5.7 you may need to set:export LDFLAGS="-L/usr/local/opt/mysql@5.7/lib"export CPPFLAGS="-I/usr/local/opt/mysql@5.7/include"For pkg-config to find mysql@5.7 you may need to set:export PKG_CONFIG_PATH="/usr/local/opt/mysql@5.7/lib/pkgconfig"To have launchd start mysql@5.7 now and restart at login: # 看这里就是启动命令brew services start mysql@5.7
Or, if you don&＃39;t want/need a background service you can just run: # 这个也可以/usr/local/opt/mysql@5.7/bin/mysql.server start
