+# Mysql 8.0 
+
+## 0x00 Install
+
+#### Download && Depends
+
+mysql的社区版本[地址](https://dev.mysql.com/downloads/)，可以直接下载到对应的二进制版本，上传至服务器即可，ubuntu下可能需要一些依赖，有这些：
+
+```shell
+sudo apt install libaio-dev libncurses5
+```
+
+#### Prepare
+
+然后直接解压下载包即可，这边我的mysql bin conf log data的路径是这样的：
+
+```shell
+xxxx@yyyyy:~/mysql$ ls
+basedir  bin  binlog  conf  datadir  include  lib   log    tmp
+```
+
+bin和include、lib这些是解压后得到的文件，我在此基础上又创建了其他目录用来保存数据等：
+
+* basedir
+* binlog binlog存放处
+* conf my.conf路径
+* datadir 数据存放点
+* log mysql的日志
+* tmp 放mysql.sock
+
+其中conf中的my.conf配置为：
+
+```conf
+[mysqld]
+lower_case_table_names =  1
+user = mysql
+server_id =  1
+port =  3306

+
+#### Initialization
+
+完成配置后，初始化mysql：
+
+```shell
+# pwd -> ${your_mysql_root_dir}
+./bin/mysqld --defaults-file=./conf/my.conf --initialize-insecure --user=${your_mysql_run_user}
+```
+
+启动mysql：
+
+```shell
+./bin/mysqld --defaults-file=./conf/my.conf &
+```
+
+使用客户端连接并且创建密码，表在mysql这个数据库中：
+
+```
+./bin/mysql -S ./tmp/mysqld.sock
+alter user 'root'@'%' identified by '${your_passwd}';
+flush privileges;
+```
+
+这里的@'%'或者localhost是设定全部IP都可访问或者仅本地登陆。
