1，突發奇想在 Mac上安裝一發mysql 玩一玩 突然啓動的時候報錯 頓時瘋狂找度娘 結果找來找去 也耽擱時間 最後還是在一篇博客找到了
2.mysql 的安裝見 https://blog.csdn.net/dongdong9223/article/details/80722654 博客
捎帶提一嘴 這個安裝 總體來講沒多大難度 可是當我在mysql目錄下啓動時候
sudo support-files/mysql.server start
突然 報錯了 問題截圖如下
說是找不到mysql目錄 不能找到 mysql server
然後 一頓尋找 先是修改了我的 配置文件
添加了
basedir=/usr/local/develope/mysql5.6
datadir=/usr/local/develope/mysql5.6/data 這兩個配置
啓動 後 還是失敗 ，記得linux 上可以指定配置文件 這個玩意忘了
第二次 修改了
第二 次還不好使
結果第三次 在博客中 地址：點我 發現瞭解決思路
1.mysql在新版中去掉了默認配置文件my.cnf如果需要可以手動創建
2.在 /etc 新建 my.cnf 文件
sudo vim my.cnf
我的配置如下
# Example MySQL config file for small systems.
#
# This is for a system with little memory (<= 64M) where MySQL is only used
# from time to time and it's important that the mysqld daemon
# doesn't use much resources.
#
# 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]
#配置mysql的文件夾 和 mysql data目錄

# 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
# (using the "enable-named-pipe" option) will render mysqld useless!

3.保存文件 （使用:wq 保存 vi使用可參考博客 點我）
修改文件讀寫權限
sudo chmod 664 /etc/my.cnf
最後重新啓動 mysql 就可以啦
