mysql多实例的安装和管理(一台服务器上运行两个mysql实例)

在服务器上搭建多mysql实例

#vim /etc/init.d/mysql_3400
#!/bin/bash
mysql_port=3400
#server_num=total
mysql_username="root"
mysql_password="password"

function_start_mysql()
{
printf "Starting MySQL...\n"
/bin/sh /usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my_conf/ios/ios_total.cnf 2>&1 > /dev/null &
}
function_stop_mysql()
{
printf "Stoping MySQL...\n"
/usr/local/mysql/bin/mysqladmin -S /home/work/mysql/ios/ios_total/mysql.sock shutdown
}
function_restart_mysql()
{
printf "Restarting MySQL...\n"
function_stop_mysql
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}')
}
