实验环境：RHEL6.4为最小化安装，mysql安装包为通用二进制安装包，版本为mysql-5.6.26
1.创建mysql用户
#useradd –M –s /sbin/nologin mysql
#yum –y install ncurses-devel libaio-devel
#安装mysql的依赖包，否则下面无法初始化成功
2.软件包解压缩
# tar xf mysql-5.6.26-linux-glibc2.5-x86_64.tar.gz -C /usr/local
# mv /usr/local/mysql-5.6.26-linux-glibc2.5-x86_64/ /usr/local/mysql
3.创建目录
# mkdir /data/{3306,3307}/data –pv
# mkdir /data/{3306,3307}/log –pv
# tree /data/ #查看目录树
4. /data/3306中新建my.cnf
# cd /data/3306/
# vim my.cnf
[client]
port = 3306
socket = /data/3306/mysql.sock
[mysqld]
port=3306
socket = /data/3306/mysql.sock
pid-file = /data/3306/data/mysql.pid
basedir = /usr/local/mysql
datadir = /data/3306/data
server-id=1
#log-bin=mysql-bin
#log-bin-index= mysql-bin.index
# LOGGING
log_error=/data/3306/log/mysql-error.log
slow_query_log_file=/data/3306/log/mysql-slow.log
slow_query_log=1
5. /data/3307中新建my.cnf
# cd ../3307/
# vim my.cnf
[client]
port = 3307
socket = /data/3307/mysql.sock
[mysqld]
port=3307
socket = /data/3307/mysql.sock
pid-file = /data/3307/data/mysql.pid
basedir = /usr/local/mysql
datadir = /data/3307/data
server-id=2
#log-bin=mysql-bin
#log-bin-index= mysql-bin.index
# LOGGING
log_error=/data/3307/log/mysql-error.log
slow_query_log_file=/data/3307/log/mysql-slow.log
slow_query_log=1
?6. 在/data/3306中新建mysql启动文件
# cd /data/3306/
# vim mysql
#!/bin/sh
[ -f /etc/init.d/functions ] && . /etc/init.d/functions
port=3306
mysql_user="root"
mysql_pwd=""
mysql_sock="/data/${port}/mysql.sock"
CmdPath="/usr/local/mysql/bin"
#startup function
usage(){
printf "Usage: /data/${port}/mysql {start|stop|restart}\n"
}
function_start_mysql()
{
if [ ! -e "$mysql_sock" ];then
/bin/sh ${CmdPath}/mysqld_safe --defaults-file=/data/${port}/my.cnf 2>&1 > /dev/null &
action "Starting MySQL..." /bin/true
else
printf "MySQL is running...\n"
exit
fi
}
#stop function
function_stop_mysql()
{
if [ ! -e "$mysql_sock" ];then
printf "MySQL is stopped...\n"
exit
else
action "Stoping MySQL..." /bin/true
${CmdPath}/mysqladmin -u ${mysql_user} -p${mysql_pwd} -S /data/${port}/mysql.sock shutdown
fi
}
#restart function
function_restart_mysql()
{
function_stop_mysql &>/dev/null
sleep 2
function_start_mysql &>/dev/null
action "Restarting MySQL..." /bin/true
}
if [ $# -ne 1 ];then
usage
fi
case $1 in
start)
function_start_mysql
;;
stop)
function_stop_mysql
;;
restart)
function_restart_mysql
;;
*)
usage
esac
#chmod +x mysql
7、在/data/3307中新建mysql启动文件
# cd /data/3307/
?# vim mysql
#!/bin/bash
[ -f /etc/init.d/functions ] && . /etc/init.d/functions
port=3307
mysql_user="root"
mysql_pwd=""
mysql_sock="/data/${port}/mysql.sock"
CmdPath="/usr/local/mysql/bin"
usage(){
printf "Usage: /data/${port}/mysql {start|stop|restart}\n"
}
#startup function
function_start_mysql()
{
if [ ! -e "$mysql_sock" ];then
/bin/sh ${CmdPath}/mysqld_safe --defaults-file=/data/${port}/my.cnf 2>&1 > /dev/null &
action "Starting MySQL..." /bin/true
else
printf "MySQL is running...\n"
exit
fi
}
#stop function
function_stop_mysql()
{
if [ ! -e "$mysql_sock" ];then
printf "MySQL is stopped...\n"
exit
else
action "Stoping MySQL..." /bin/true
${CmdPath}/mysqladmin -u ${mysql_user} -p${mysql_pwd} -S /data/${port}/mysql.sock shutdown
fi
}
#restart function
function_restart_mysql()
{
function_stop_mysql &>/dev/null
sleep 2
function_start_mysql &>/dev/null
action "Restarting MySQL..." /bin/true
}
case $1 in
start)
