mac 安装mysql 报错“ERROR 2002 (HY000): Can not connect to local MySQL server through socket '/tmp/mysql.sock' (2)” 解决办法

首先安装 homebrew

再 brew install mysql

之后连接 mysql  无论是登录还是修改初始密码都会报如下的错误
ERROR 2002 (HY000): Can not connect to local MySQL server through socket ‘/tmp/mysql.sock‘ (2)

运行如下解决：参考 http://www.thinksaas.cn/group/topic/347978/

unset TMPDIR
mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp

这时候可以通过 http://blog.sina.com.cn/s/blog_9ea3a4b70101ihl3.html  进行登录密码修改等等。

然后cd bin用
$ sudo ./mysql_secure_installation 
来修改root密码，默认为空，显然不太安全，然后根据提示酌情配置，因为是开发环境不用那么严格限制。
$ sudo ./mysqld_safe 
来启动mysql
$ sudo ./mysql -u root -p 
输入刚才设置的root密码来登录mysql
$ sudo ./mysqld_safe stop 
停止mysql

我这边移除了mysql.sock文件后,重启服务就成功了. 还有一种情况,就是加入galera后,可能是server.cnf配置信息出了问题导致的,修改后,重新运行galera即可,数据库就可以启动成功了. mariadb报:ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111 "Connection refused") 原文地址:h
