mac上用homebrew安装mysql(Mac自带homebrew)
brew install mysql
安装后如下：
If you need to have mysql@5.7 first in your PATH run: echo 'export PATH="/usr/local/opt/mysql@5.7/bin:$PATH"' >> /Users/chenyang/.bash_profile
For compilers to find mysql@5.7 you may need to set: export LDFLAGS="-L/usr/local/opt/mysql@5.7/lib" export CPPFLAGS="-I/usr/local/opt/mysql@5.7/include"
To have launchd start mysql@5.7 now and restart at login: brew services start mysql@5.7 Or, if you don't want/need a background service you can just run: /usr/local/opt/mysql@5.7/bin/mysql.server start
做好my.cnf的设置，我这里的路径为：/usr/local/etc/my.cnf，内容如下：
[client] default-character-set=utf8 #password = your_password port = 3306 socket = /tmp/mysql/mysql.sock [mysqld] character-set-server=utf8 init_connect='SET NAMES utf8 port = 3306 socket = /tmp/mysql/mysql.sock skip-external-locking key_buffer_size = 16M max_allowed_packet = 1M table_open_cache = 64 sort_buffer_size = 512K net_buffer_length = 8K read_buffer_size = 256K read_rnd_buffer_size = 512K myisam_sort_buffer_size = 8M character-set-server=utf8 init_connect='SET NAMES utf8'
#skip-networking replication log-bin=mysql-bin
binlog_format=mixed
server-id = 1
[mysqldump] quick max_allowed_packet = 16M
[mysql] no-auto-rehash #safe-updates default-character-set=utf8
[myisamchk] key_buffer_size = 20M sort_buffer_size = 20M read_buffer = 2M write_buffer = 2M
[mysqlhotcopy] interactive-timeout
此时在控制台运行会报错：
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
google各教程教程,发现就是mysql.sock这个文件的路径问题,最后解决办法:
修改/usr/local/etc/my.cnf文件(如果没有自创建),将文件里面socket的路径指向你mysql的安装路径,使用了很多网上的方式,结果还是不行,应该是安装路径不一样,你必须找到你的路径,(mysql版本5.7.20)路径是在/usr/local/var/mysql/
[client] default-character-set=utf8 #password = your_password port = 3306 socket = /usr/local/var/mysql/mysql.sock #/tmp/mysql/mysql.sock
[mysqld] character-set-server=utf8 init_connect='SET NAMES utf8 port = 3306 socket = /usr/local/var/mysql/mysql.sock #/tmp/mysql/mysql.sock
修改后问题解决,数据库正常连接
