安装

双击下载好的dmg文件，会弹出pkg弹框，再双击pkg图标，进入安装界面，在安装界面上一路继续，就安装成功了。

环境变量

第一步，在终端切换到根目录，编辑./.bash_profile文件

?~cd~?~vim./.bash_profile

第二步，进入vim编辑环境，按下i进入insert模式，输入

exportPATH=$PATH:/usr/local/mysql/binexportPATH=$PATH:/usr/local/mysql/support-files

第三步，按下 esc 退出 insert 模式，输入 :wq 保存配置文件

:wq

第四步，在终端界面输入以下命令，让配置文件的修改生效，并查看环境变量是否设置成功

?~echo$PATH/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin?~source~/.bash_profile?~echo$PATH/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/mysql/bin:/usr/local/mysql/support-files?~

MYSQL服务的启停和状态的查看

查看MYSQL的服务状态

?~sudomysql.serverstatusPassword:ERROR!MySQLisnotrunning

启动MYSQL服务

?~sudomysql.serverstartStartingMySQL.Loggingto'/usr/local/mysql/data/mj.local.err'.SUCCESS!

停止MYSQL服务

?~sudomysql.serverstopShuttingdownMySQL.SUCCESS!

重启MYSQL服务

?~sudomysql.serverrestartERROR!MySQLserverPIDfilecouldnotbefound!StartingMySQL.SUCCESS!

启动

第一步，终端界面下输入

?~sudomysql.serverstartStartingMySQL.Loggingto'/usr/local/mysql/data/mj.local.err'.SUCCESS!

第二步，启动MYSQL服务，启动成功后继续输入

?~mysql-uroot-p

第三步，直接回车，进入数据库，看到以下欢迎界面

Enterpassword:WelcometotheMySQLmonitor.Commandsendwith;or\g.YourMySQLconnectionidis1Serverversion:5.6.41MySQLCommunityServer(GPL)Copyright(c)2000,2018,Oracleand/oritsaffiliates.Allrightsreserved.OracleisaregisteredtrademarkofOracleCorporationand/oritsaffiliates.Othernamesmaybetrademarksoftheirrespectiveowners.Type'help;'or'\h'forhelp.Type'\c'toclearthecurrentinputstatement.mysql>

备注：默认安装成功后没有初始密码，所以密码不用输入，直接回车即可。

初始化设置

设置初始密码，进入mysql数据库之后执行下面的语句，设置当前root用户的密码为root

?~mysql-uroot-pEnterpassword:WelcometotheMySQLmonitor.Commandsendwith;or\g.YourMySQLconnectionidis2Serverversion:5.6.41MySQLCommunityServer(GPL)Copyright(c)2000,2018,Oracleand/oritsaffiliates.Allrightsreserved.OracleisaregisteredtrademarkofOracleCorporationand/oritsaffiliates.Othernamesmaybetrademarksoftheirrespectiveowners.Type'help;'or'\h'forhelp.Type'\c'toclearthecurrentinputstatement.mysql>setpassword=password('root');QueryOK,0rowsaffected(0.01sec)mysql>

退出MYSQL的界面

mysql>exitBye?~

配置

进入到 /usr/local/mysql/support-files目录，里面有个文件my-default.cnf

?~cd/usr/local/mysql/support-files?support-fileslltotal64-rwxr-xr-x1rootwheel1.1K6152018binary-configure-rw-r--r--1rootwheel773B6152018magic-rw-r--r--1rootwheel1.1K6152018my-default.cnf-rwxr-xr-x1rootwheel894B6152018mysql-log-rotate-rwxr-xr-x1rootwheel10K6152018mysql.server-rwxr-xr-x1rootwheel1.0K6152018mysqld_multi.server?support-files

将目录下的my-default.cnf文件复制到桌面上，改名为my.cnf，

?support-fileslltotal64-rwxr-xr-x1rootwheel1.1K6152018binary-configure-rw-r--r--1rootwheel773B6152018magic-rw-r--r--1rootwheel1.1K6152018my-default.cnf-rwxr-xr-x1rootwheel894B6152018mysql-log-rotate-rwxr-xr-x1rootwheel10K6152018mysql.server-rwxr-xr-x1rootwheel1.0K6152018mysqld_multi.server?support-filescpmy-default.cnf/Users/a1/Desktop/my.cnf

将内容替换为下面的内容

[mysqld]default-storage-engine=INNODBcharacter-set-server=utf8port=3306[client]default-character-set=utf8

将修改后的my.cnf文件复制到/etc目录下，重启MYSQL

?/etccp/Users/a1/Desktop/my.cnf./cp:./my.cnf:Permissiondenied?/etcsudocp/Users/a1/Desktop/my.cnf./Password:?/etclltotal1064......-rw-------1rootwheel7.3K22914:10master.passwd-rw-r--r--1rootwheel1.2K51717:24my.cnf-rw-r--r--1rootwheel11B22914:43nanorc-rw-r--r--1rootwheel53B22914:09networks......?/etc

备注：拷贝文件到etc目录需要系统权限，因此需要在命令前加sudo
