  4. 打开终端,输入“sudo vim /etc/my.cnf”,在弹出的编辑器中按键盘的 i键进入编辑模式,输入以下内容:

# Example MySQL config file for medium systems.
#
# This is for a system with little memory (32M - 64M) where MySQL plays
# an important part, or systems up to 128M where MySQL is used together with
# other programs (such as a web server)
#
# MySQL programs look for option files in a set of
# 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.
# The following options will be passed to all MySQL clients
[client]
default-character-set=utf8
#password   = your_password
port        = 3306
socket      = /tmp/mysql.sock
# Here follows entries for some specific programs
# The MySQL server
[mysqld]
character-set-server=utf8
init_connect='SET NAMES utf8
port        = 3306
socket      = /tmp/mysql.sock

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'
# Don't listen on a TCP/IP port at all. This can be a security enhancement,  
# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (via the "enable-named-pipe" option) will render mysqld useless!

# Replication Master Server (default)
# binary logging is required for replication
log-bin=mysql-bin
# binary logging format - mixed recommended
binlog_format=mixed
# required unique id between 1 and 2^32 - 1
# defaults to 1 if master-host is not set
# but will not function as a master if omitted
server-id   = 1
# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
#    the syntax is:
#
#    CHANGE MASTER TO MASTER_HOST=, MASTER_PORT=,
#    MASTER_USER=, MASTER_PASSWORD= ;
#
#    where you replace , ,  by quoted strings and
#     by the master's port number (3306 by default).  
#
#    Example:
#
#    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
#    MASTER_USER='joe', 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 to
#    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     =
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password =
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port     =
#
# binary logging - not required for slaves, but recommended
#log-bin=mysql-bin
# Uncomment the following if you are using InnoDB tables
#innodb_data_home_dir = /usr/local/mysql/data
#innodb_data_file_path = ibdata1:10M:autoextend
#innodb_log_group_home_dir = /usr/local/mysql/data
# You can set .._buffer_pool_size up to 50 - 80 %
# of RAM but beware of setting memory usage too high
#innodb_buffer_pool_size = 16M
#innodb_additional_mem_pool_size = 2M
# Set .._log_file_size to 25 % of buffer pool size
#innodb_log_file_size = 5M
#innodb_log_buffer_size = 8M
#innodb_flush_log_at_trx_commit = 1
#innodb_lock_wait_timeout = 50

编辑完成后,点击esc,然后将输入法设置为英文模式,输入:wq回车保存(注意wq前面的冒号也需要输入)。

  1. 设置文件权限
    打开终端,输入“sudo chmod 664 /etc/my.cnf”,在系统设置中重启mysql服务,到此mysql安装大功告成。
  2. 配置mysql环境变量
    打开终端,输入 vi ~/.bash_profile ,在里面添加如下:
export PATH=$PATH:/usr/local/mysql-5.7.31-macos10.14-x86_64/bin

编辑完成后,点击esc,然后将输入法设置为英文模式,输入:wq回车保存,在终端使用“source .bash_profile”命令,使配置生效。

  1. 修改默认密码
    在终端中使用“mysql -uroot -p”命令,然后提示要求输入密码(输入时密码不可见,不要以为没有输入上,把上面记录下来的密码复制粘贴直接回车即可)。
    进入mysql后可以依次使用下面的命令修改密码
alter user 'root'@'localhost' identified by '123456';
create user 'root'@'%' identified by '123456';
grant all privileges on *.* to 'root'@'%';
flush privileges;
quit;

到此为止所有配置都完成,可以使用Navicat等第三方工具连接Mysql进行使用了。
