Kali中安裝mysql自動安裝腳本

查看創建的mysql用戶：

cat /etc/passwd | grep mysql

　　安裝步驟：

1.先刪除mariadb

apt-get autoremove --purge mariadb-client-core-10.3
apt-get autoremove --purge

2.把mysql的壓縮包文件放入到/usr/local

3.執行解壓命令

tar -zxvf mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz

4.修改文件名

mv mysql-5.7.20-linux-glibc2.12-x86_64 mysql

5.創建用戶：

 userdel mysql
 groupadd mysql
useradd -r -g mysql mysql
chown -R mysql:mysql mysql

　6.切換到mysql用戶：

su mysql

　7.進入到安裝目錄：

cd mysql

8.執行初始數據命令：（這里安裝的5.7 其他版本可能不一樣）參考：https://www.cnblogs.com/xuanzhi201111/p/5148113.html

./bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

9.exit退出mysql用戶

10.拷貝文件：

cp support-files/mysql.server /etc/init.d/mysql
cp support-files/my-default.cnf /etc/my.cnf   （5.7沒有這個文件，自己找一個）
cp bin/mysql /usr/bin/

　　11.創建log文件輸出路徑：

mkdir log
touch log/mysqld.log
chown -R mysql:mysql log/
chmod -R 755 log/mysqld.log

　　12.修改配置文件vim /etc/init.d/mysql

basedir=/usr/local/mysql
datadir=/usr/local/mysql/data  （這個拷貝文件中如果添加，就不需要改了）

　　修改下配置文件：vim /etc/my.cnf

[client]
default-character-set=utf8
[mysqld]
character-set-server=utf8
datadir=/usr/local/mysql/data
basedir=/usr/local/mysql
socket=/tmp/mysql.sock
max_heap_table_size = 512M
[mysqld_safe]
log-error=/usr/local/mysql/log/mysqld.log
另外將被注釋掉的innodb_buffer_pool_size = 128M放開（缺省值是8M，在批量插入數據過多時會產生錯誤，memsql設置128即可，MySQL需要設置為9G）

　　啟動數據庫：

service mysql start　

運行命令：vi /etc/my.cnf，編輯文件

在文件的[mysqld]標簽下添加一句：skip-grant-tables

service mysql stop

service mysql start

進入數據庫：mysql -u root

使用數據庫：use mysql;
運行：

update mysql.user set authentication_string=password('root') where user='root';    
root_password替換成你想要的密碼

　　exit退出

把my.conf的skip-grant-tables刪除，重啟數據庫，

 修改自己的賬號：

ALTER USER 'root'@'localhost' IDENTIFIED BY 'root';

　　刷新權限

flush privileges;

　　退出：

quit;

設置訪問權限：

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;

　　刷新訪問權限表

flush privileges;
刷新服務：
service mysql restart
重啟服務：

service mysql restart;

添加用戶：

CREATE USER '用戶名'@'localhost' IDENTIFIED BY '密碼';

　　自動安裝腳本：網上的好多都不能用。
