1.安装脚本:

#!/bin/sh

echo "安装前请确保mysql已被删除"
sudo rm -r /opt/mysql
sudo rm /etc/my.cnf
sudo groupadd mysql
sudo useradd -r -g mysql mysql
#wget http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.13-linux-glibc2.5-x86_64.tar.gz
tar -zxvf mysql-5.6.13-linux-glibc2.5-x86_64.tar.gz
sudo mv mysql-5.6.13-linux-glibc2.5-x86_64 /opt/mysql
sudo ln -s /opt/mysql /usr/local/mysql
#初始化数据库
sudo /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
sudo chown -R mysql:mysql /opt/mysql #添加权限;
#启动shell放到系统服务
sudo cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
#配置文件放至全局
sudo cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf
#修改data目录权限
#cd /opt/mysql
#sudo chmod -R 755 data
echo "----ok----"

2.mysql 配置与用户权限管理

(1)启动mysql
sudo /etc/init.d/mysql start

(2)登录
初次登录 不需要密码 ./mysql/bin/mysql -u root

(3)设置密码
update mysql.user set password=password('root') where user='root';
grant privileges;
下次登录时就需要 密码
./mysql/bin/mysql -u root -p


(4)设置访问权限/资源限制
GRANT ALL ON *.* to root@'175.102.99.%' IDENTIFIED BY 'passwd';
GRANT ALL ON *.* to user@'172.16.8.%' IDENTIFIED BY 'passwd';

FLUSH PRIVILEGES;
官方参考:http://dev.mysql.com/doc/refman/5.1/zh/database-administration.html#request-access

(5)mysql 重启
sudo /etc/init.d/mysql restart


期间问题小计:

三种启动方式:
mysqld  '在bin目录下'

[mysqld], [server], [mysqld-major-version]

mysql.server'在support-files目录下'
'如果你使用Linux 服务器RPM软件包(MySQL-server-VERSION.rpm),mysql.server脚本将安装到/etc/init.d目录下,'
[mysqld], [mysql.server], [server]

mysqld_safe  '在bin目录下'
'使用mysqld_safe而不使用mysqld的好处是mysqld_safe“守护”其mysqld进程,如果用kill –9发送的信号或由于其它原因(例如分段故障)进程终止,则重启进程。'
[mysqld], [server], [mysqld_safe]

#ok配置文件: /etc my.cnf 日志路径;/var/log/mysql/mysqld.log   启动路径:/etc/init.d/mysql   安装路径:/opt/mysql/bin  软连接:/usr/local/mysql


备份脚本:

#!/bin/sh
dir_name=/opt/mysql/dump/rundong_$(date +%Y%m%d)
[ -d /opt/mysql/dump ] || mkdir /opt/mysql/dump
[ -d ${dir_name} ] || mkdir ${dir_name}

#mysqldump--    --opt 该选项是速记;它可以给出很快的转储操作并产生一个可以很快装入MySQL服务器的转储文件

#于备份一个整个的数据库:
/opt/mysql/bin/mysqldump --opt -d -uroot -ppasswd  databse > ${dir_name}.sql

#sudo chown -R mysql:mysql /opt/mysql #添加权限;
/opt/mysql/bin/mysqldump --opt --tab ${dir_name} -udump -ppasswd database
