mysql 启动停止脚本 and mysql 迁移 导入和导出

####监控脚本

[root@pdb~]# more /opt/VRTS/scripts/mysql_monitor.sh
#!/bin/sh
n=`ps -ef |grep mysql|grep "port=3306"|wc -l`
if test $n -eq 0
then exit 100
else exit 110
fi
[root@pdb~]# sh /opt/VRTS/scripts/mysql_monitor.sh

##############2 启动
[root@pdb~]# cd /opt/VRTS/scripts/mysql_monitor.sh

[root@pdb~]# cd /opt/VRTS/scripts
[root@pdbscripts]# ls
mysql_monitor.sh start_mysql.sh stop_mysql.sh

[root@pdbscripts]# more start*.sh
base=/oa/oas_mysql/app/mysql/
datadir=/oa/oas_mysql/data/mydata
config_file=/oa/oas_mysql/app/mysql/my.cnf
user=mysql
/oa/oas_mysql/app/mysql/bin/mysqld_safe --defaults-file=${config_file} --datadir=${datadir} --user=$user &

#########3 停止
[root@pdbscripts]# more stop*.sh
/oa/oas_mysql/app/mysql/bin/mysqladmin -uroot -pmysql shutdown

#############sample mysql  sample 导入和导出

############mysql 导入导出
https://www.cnblogs.com/smail-bao/p/6402265.html
CREATE DATABASE `db_monitor` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

赋予数据库（zqxt）权限给某用户，可以是已经存在的用户或新用户名
GRANT ALL PRIVILEGES ON zqxt.* TO "任意用户名"@"localhost" IDENTIFIED BY "新密码";

刷新权限
FLUSH PRIVILEGES;

退出数据库shell
EXIT;

1.备份单个数据库的数据和结构(,数据库名mydb)

mysqldump -uroot-p123456 db_monitor>c:db_monitor.sql

2.还原单个数据库(需指定数据库)

(1) mysql>use mydb

mysql>source f:mydb.sql

(2) mysql -uroot -p123456 mydb <c:db_monitor.sql

# 输入密码开始导入数据

#######command

https://dev.mysql.com/doc/refman/8.0/en/testing-server.html
If you specify a database name, mysqlshow displays a list of the tables within the database:
shell> bin/mysql -e "SELECT User, Host, plugin FROM mysql.user" mysql
shell> bin/mysqlshow mysql

Use mysqladmin to verify that the server is running. The following commands provide simple tests to check whether the server is up and responding to connections:
shell> bin/mysqladmin version
shell> bin/mysqladmin variables

###############phpadmin连接远程数据库

phpadmin连接远程数据库
1、打开wampserver下phpmyadmin的目录在D:wampapps下 D:wampappsphpmyadmin4.1.14

2、找到config.inc.php文件，打开修改要连接的远程MySQL的host，user和password，更改这3个信息即可

其中必须保证数据库有被远程连接的权限

/* Authentication type */
$cfg['Servers'][$i]['verbose'] = 'mysql wampserver';
//$cfg['Servers'][$i]['auth_type'] = 'cookie';
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'admin';
$cfg['Servers'][$i]['password'] = 'root';
/* Server parameters */
$cfg['Servers'][$i]['host'] = '192.168.1.154';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['compress'] = false;
/* Select mysql if your server does not have mysqli */
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['AllowNoPassword'] = true;

3.如果要用root登录此时也应该把host修改为localhost；
