To secure it run:mysql_secure_installation #初始化配置MySQL is configured to only allow connections from localhost by defaultTo connect run:mysql -uroot #运行连接mysql5.7 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 mysql5.7 first in your PATH run: #配置环境变量echo export PATH/usr/local/opt/mysql5.7/bin:$PATH ~/.bash_profileFor compilers to find mysql5.7 you may need to set:export LDFLAGS-L/usr/local/opt/mysql5.7/lib #想要系统编译运行认识mysql5.7配置环境变量export CPPFLAGS-I/usr/local/opt/mysql5.7/includeTo have launchd start mysql5.7 now and restart at login:brew services start mysql5.7 #启动安装后的mysql数据库Or, if you dont want/need a background service you can just run:/usr/local/opt/mysql5.7/bin/mysql.server start #通过配置文件启动mysql数据库根据安装后提示信息第一步配置环境变量家目录下vi .bashprofile文件将安装后提示的export PATH/usr/local/opt/mysql5.7/bin:$PATHexport LDFLAGS-L/usr/local/opt/mysql5.7/libexport CPPFLAGS-I/usr/local/opt/mysql5.7/include加入到.bash_profile文件中加入保存后使用source .bashprofile使配置到环境变量生效完成后使用:brew services start mysql5.7或者你根据配置文件启动mysql数据库服务启动后开始初始化配置运行mysql_secure_installation提示如下Securing the MySQL server deployment.Connecting to MySQL using a blank password.VALIDATE PASSWORD PLUGIN can be used to test passwordsand improve security. It checks the strength of passwordand allows the users to set only those passwords which aresecure enough.
