brew 安装MySQL数据库_"a \"/etc/my.cnf\" from another install may interf

利用brew安装MySQL好处就是方便管理，安装简单，快速升级，万不得已卸载也就一行命令搞定 不用输入好多命令删除相应目录那么麻烦

输入安装命令 

$ brew install mysql 

安装过程中输出的重要日期信息 

==> Caveats

==> openssl

A CA file has been bootstrapped using certificates from the SystemRoots

keychain. To add additional certificates (e.g. the certificates added in

the System keychain), place .pem files in

  /usr/local/etc/openssl/certs

 

and run

  /usr/local/opt/openssl/bin/c_rehash

 

openssl is keg-only, which means it was not symlinked into /usr/local,

because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries.

 

If you need to have openssl first in your PATH run:

  echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile

 

For compilers to find openssl you may need to set:

  export LDFLAGS="-L/usr/local/opt/openssl/lib"

  export CPPFLAGS="-I/usr/local/opt/openssl/include"

 

For pkg-config to find openssl you may need to set:

  export PKG_CONFIG_PATH="/usr/local/opt/openssl/lib/pkgconfig"

 

==> mysql

We've installed your MySQL database without a root password. To secure it run:

    mysql_secure_installation

 

MySQL is configured to only allow connections from localhost by default

 

To connect run:

    mysql -uroot

 

A "/etc/my.cnf" from another install may interfere with a Homebrew-built

server starting up correctly.

 

To have launchd start mysql now and restart at login:

  brew services start mysql

Or, if you don't want/need a background service you can just run:

  mysql.server start

安装完成后默认服务时启动的，在任何目录下可以输入这个命令来操作MySQL服务

$ mysql.server 

Usage: mysql.server  {start|stop|restart|reload|force-reload|status}  [ MySQL server options ]
