Modify the MySQL encoding format under mac terminal -- cannot find the my-default.cnf and my. cnf, cannot find mydefault. cnf

Modify the MySQL encoding format under mac terminal -- cannot find the my-default.cnf and my. cnf, cannot find mydefault. cnf

First, make sure that MySQL is correctly installed.

1-configure the environment variable path first

1.1 open the terminal and enter: cd ~

Will enter ~ Folder,

1.2 then enter: touch. bash_profile

After you press enter to execute,

1.3 enter: open-e. bash_profile

This file will be opened in TextEdit (if environment variables have not been configured before, this should be a blank document ).

If there is content, enter it before the Terminator. If there is no content, enter the following statement:

Export PATH =$ {PATH}:/usr/local/mysql/bin

Then, save and exit TextEdit (it must be quit), close the terminal, and exit.

In this case, you can directly log on to MySQL using the following statement:

> Mysql-uroot-p

1.4 close MySQL !!!! (Disable MySQL in system preference settings)

2-The point is coming !!!

2.1 check the support-files folder ("go to folder" under Finder; Path:/usr/local/mysql/support-files)

There is no my-default.cnf or my. cnf file... if there is, open the Add directly

Add default-character-set = utf8 under [client]. The default character set is utf8.
Add in [mysqld]
Default-character-set = utf8 default character set: utf8
Init_connect = 'set NAMES utf8' (SET utf8 encoding for connecting to the mysql database to run utf8) after modification, restart mysql to view the current data encoding format. > Show variables like '% char %'; + -------------------------- + ---------------------------- +
| Variable_name | Value |
+ -------------------------- + ---------------------------- +
| Character_set_client | utf8 |
| Character_set_connection | utf8 |
| Character_set_database | utf8 |
| Character_set_filesystem | binary |
| Character_set_results | utf8 |
| Character_set_server | utf8 |
| Character_set_system | utf8 |
| Character_sets_dir |/usr/share/mysql/charsets/|
+ -------------------------- + ---------------------------- +

If the terminal displays the above style, it will be OK; otherwise, continue to look at it:

2.2 support-files folder contains no my-default.cnf or my. cnf file, you need to create my. cnf under/etc

$ Cd/etc

$ Sudo vim my. cnf

2.3 After completing the previous step, the vim mode is displayed. Copy the (*** text) content and paste it in (excluding *** text );

2.4 check whether the first line of vim "#" has been lost after the paste is successful (I have lost it myself ~~ Haha ~), If all are OK, click esc to exit editing,

: Wq! -- Force exit after saving. [add several edit commands: dd to delete the row where the cursor is located; dw to delete a word; x to delete the current character].

# Example MySQL config file for medium systems.

# This is for a system with little memory (32 M-64 M) where MySQL plays
# An important part, or systems up to 128 M where MySQL is used together
# Other programs (such as a web server)
#
# MySQL programs look for option files in a set
# Locations which depend on the deployment platform.
# You can copy this option file to one of those
# Locations. For information about these locations, see:
# Http://dev.mysql.com/doc/mysql/en/option-files.html
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# With the "-- help" option.

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose
# Two methods:
#
#1) Use the change master to command (fully described in our manual )-
# The syntax is:
#
# Change master to MASTER_HOST = # MASTER_USER = <user>, MASTER_PASSWORD = <password>;
#
# Where you replace # <Port> by the master's port number (3306 by default ).
#
# Example:
#
# Change master to MASTER_HOST = '192. 564.12.1 ', MASTER_PORT = 125,
# MASTER_USER = 'job', MASTER_PASSWORD = 'secret ';
#
# OR
#
#2) Set the variables below. However, in case you choose this method, then
# Start replication for the first time (even unsuccessfully, for example
# If you mistyped the password in master-password and the slave fails
# Connect), the slave will create a master.info file, and any later
# Change in this file to the variables 'values below will be ignored and
# Overridden by the content of the master.info file, unless you shutdown
# The slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (Commented) and instead use change master to (see above)
#
# Required unique id between 2 and 2 ^ 32-1
# (And different from the master)
# Defaults to 2 if master-host is set
# But will not function as a slave if omitted
# Server-id = 2
#
# The replication master for this slave-required
# Master-host = #
# The username the slave will use for authentication when connecting
# To the master-required
# Master-user = <username>
#
# The password the slave will authenticate with when connecting
# The master-required
# Master-password = <password>
