(2) add my.cnf
By default, mysql installed by brew will not generate a my.cnf file. You need to assign the my-default.cnf file in the /usr/local/Cellar/mysql/5.6.27/support-files file to /etc/ and rename it to my.cnf. In this way, you can modify the mysql configuration by modifying my.cnf in the future.
(3):
MySQL connection not working: 2002 No such file or directory
Required: add php.ini
3.1 Open some required extensions
3.2 Setting pdo_mysql.default_socket
mysql.default_socket = /tmp/mysqld.sock
pdo_mysql.default_socket= /tmp/mysqld.sock
mysqli.default_socket =/tmp/mysqld.sock
(4) The mac opens the slow log, error log and normal log of mysql.
The configuration method is as follows, add the following in /etc/my.cnf:
general_log = 1
general_log_file = /var/log/mysql/mysql.log
#
# Error log - should be very few entries.
#
log_error = /var/log/mysql/error.log
#
# Here you can see queries with especially long duration
slow-query-log = /var/log/mysql/mysql-slow.log
long_query_time = 2
#log-queries-not-using-indexes
Note: The things to note here are:
Before mysql5.11 , the open variable of slow log was: log_slow_queries
And now it's show-query-log
5: An error is reported when brew install php56 :
