Mac的arm架构芯片安装mysql8和安装中的问题

1. 下载mysql
   地址:https://dev.mysql.com/downloads/mysql/
2. 解压到某个地方
3. 在support-files 文件夹下面新建 my.conf 配置文件,内容如下

[client]
  default-character-set=UTF8MB3
  #password   = your_password
  port        = 3306
  #修改的socket文件的位置，默认是走的/tmp下的mysql.sock会有冲突
  #这是报错  Another process with pid 77346 is using unix socket file.
  #客户端也需要这个和服务端的一致
  socket      = /Users/yaoqiang/app/mysql-8.0.31/mysql.sock
[mysqld]
  #innodb_force_recovery = 1
  event_scheduler=ON
  character-set-server=UTF8MB3
  port        = 3306
  mysqlx_port = 33060
  bind-address=127.0.0.1
  #修改的socket文件的位置，默认是走的/tmp下的mysql.sock会有冲突
  socket      = /Users/yaoqiang/app/mysql-8.0.31/mysql.sock
  mysqlx_socket= /Users/yaoqiang/app/mysql-8.0.31/mysqlx.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
  init_connect='SET NAMES utf8'
  #修改mysql的主目录
  basedir=/Users/yaoqiang/app/mysql-8.0.31
  #添加data文件的目录，存储各种数据和日志
  datadir=/Users/yaoqiang/app/mysql-8.0.31/data
  
  log-bin=mysql-bin
  binlog_format=mixed
  server-id   = 1
  sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
  # mysql是出于安全考虑，默认拒绝用root账号启动mysql服务,所以我们加下面一行
  # 指定mysql用户来启动mysql服务。
  user=mysql
  
[mysqldump]
  quick
  max_allowed_packet = 16M

[mysql]
  no-auto-rehash
  # Remove the next comment character if you are not familiar with SQL
  #safe-updates
  default-character-set=UTF8MB3

[myisamchk]
  key_buffer_size = 20M
  sort_buffer_size = 20M
  read_buffer = 2M
  write_buffer = 2M

[mysqlhotcopy]
  interactive-timeout

4. 进入mysq 目录

cd /Users/yaoqiang/app/mysql-8.0.31/bin

5. 执行 mysql 初始化
   若提示不安全则去设置里点击允许

./mysqld --defaults-file=/Users/yaoqiang/app/mysql-8.0.31/support-files/my.conf --initialize-insecure

6. 启动mysql

./mysqld --defaults-file=/Users/yaoqiang/app/mysql-8.0.31/support-files/my.conf
# 如果出现[ERROR] Fatal error: Please read "Security" section of the manual to find out how to run mysqld 则运行以下命令
sudo ./mysqld --defaults-file=/Users/yaoqiang/app/mysql-8.0.31/support-files/my.conf --user=root

7. 进去mysql

./mysql -h 127.0.0.1 -uroot -p

8. 创建用户（若使用随机生成密码，需要记住密码）

create user 'root'@'%' identified by 'root';

或者

create user 'holddie'@'%' IDENTIFIED BY RANDOM PASSWORD;

9. 授权远程同步

grant replication slave on *.* to 'holddie'@'%';

10. 保存刷新

flush privileges;
