mac10.10.4

mysql-5.7.10-osx10.10-x86_64

Mac小试牛刀，安装个mysql玩玩 

默认安装到目录/usr/local下

dsmemberutil checkmembership -U mysql -G mysql

cd /usr/local
ln -s mysql-5.6.27-linux-glibc2.5-x86_64 mysql
cd mysql

# 将mysql/bin加入环境变量，也就是/etc/bashrc文件中

cat "export PATH=$PATH:/usr/local/mysql/bin " >> /etc/bashrc

# 加入默认配置文件
my_print_defaults命令可以看到

Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /usr/local/mysql/etc/my.cnf ~/.my.cnf

# 我将my.cnf放到/etc/my.cnf

# 初始化数据文件

mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/mysql3306

mysql_ssl_rsa_setup

# 最后会出现

2015-12-16T12:12:43.106693Z 1 [Note] A temporary password is generated for root@localhost: T:NRzh/_3cPA 

最后就是初始密码，将他改掉

mysqladmin -u root password 'root' -p

输入你的密码：T:NRzh/_3cPA

# 启动后先改密码

# 否则执行时指定配置文件

mysqld_multi --defaults-extra-file=/usr/local/mysql/my.cnf report
# or
mysqld_multi --defaults-file=/usr/local/mysql/my.cnf report
# or
mysqld_multi report

# 查看
mysqld_multi report

# 启动
mysqld_multi start 3306

# 停止
mysqld_multi stop 3306 --password=root
#or 最好用这个
mysqladmin -S /tmp/mysql_3306.sock -uroot -p shutdown

# 创建授权新用户，开始使用
