Shell修改MySQL初始密码，开启远程登录，授权远程登录用户

1、修改初始密码：
mysqladmin -uroot -pvyCE2UwSaqx3xofR password "123456"
mysqladmin -u root -proot password 123456
2、开启远程登录，授权远程登录用户：
mysql -uroot -proot -e "grant all privileges on *.* to 'root'@'%' identified by 'root' with grant option;"
3、使授权立即生效：
mysql -uroot -proot -e "flush privileges;"

4、使用-e进行参数传递，适合简单的命令，如

mysql -uuser -ppasswd -e "create database db;"

直接用命令导入：

mysql -uuser -ppasswd < test.sql

===============================================

允许root登录

vi /etc/ssh/sshd_config

将PermitRootLogin值改yes

允许不输入密码登录

将PermitEmptyPasswords yes前面的#号去掉

重启服务：service sshd restart（/etc/initd.d/sshd restart）

======================================================

mysql启动关闭shell脚本 #!/bin/sh    mysql_port=3306  mysql_username="root"  mysql_password=""    function_start_mysql()  {  printf "Starting MySQL...\n"  /bin/sh /data/mysql/bin/mysqld_safe --defaults-file=/data/mysql/${mysql_port}/my.cnf 2>&1 > /dev/null &  }    function_stop_mysql()  {  printf "Stoping MySQL...\n"  /data/mysql/bin/mysqladmin -u ${mysql_username} -p${mysql_password} -S /data/mysql/mysql.sock shutdown    }    function_restart_mysql()  {  printf "Restarting MySQL...\n"  function_stop_mysql  sleep 5  function_start_mysql  }    function_kill_mysql()  {  kill -9 $(ps -ef | grep 'bin/mysqld_safe' | grep ${mysql_port}  | awk '{printf $2}')  kill -9 $(ps -ef | grep 'libexec/mysqld' | grep ${mysql_port}  | awk '{printf $2}')  }   if [ "$1" = "start" ]; then  function_start_mysql  elif [ "$1" = "stop" ]; then  function_stop_mysql  elif [ "$1" = "restart" ]; then  function_restart_mysql  elif [ "$1" = "kill" ]; then  function_kill_mysql  else  printf "Usage: /data/mysql/${mysql_port}/mysql    {start|stop|restart|kill}\n"  fi
