Linux:Centos 安装mysql5.6

1.先查看系统上有没有安装了旧版本的MySQL,用下面的命令:

rpm -qa | grep mysql

如果有,用以下命令卸载

rpm -e --nodeps 上步显示mysql名称

安装编译mysql 需要的依赖包

yum install libevent* libtool* autoconf* libstd* ncurse* bison* openssl*

yum -y install gcc gcc-c++

2.安装cmake,mysql5.5之后需要用cmake支持编译安装,下载安装cmake

wget http://www.cmake.org/files/v2.8/cmake-2.8.12.1.tar.gz

tar -xf cmake-2.8.12.1.tar.gz

cd cmake-2.8.12.1

./configure && make && make install

检查cmake安装好了没

cmake --version

3.下载mysql

wget http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.14.tar.gz

tar xvf mysql-5.6.14.tar.gz

cd mysql-5.6.14

上面如果下载失败,可以到这里下载:http://download.csdn.net/detail/terry_water/6973721

4.编译安装

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DSYSCONFDIR=/etc -DWITH_MYISAM_STORAGE_ENGINE=1-DWITH_INNOBASE_STORAGE_ENGINE=1-DWITH_MEMORY_STORAGE_ENGINE=1-DWITH_READLINE=1-DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock -DMYSQL_TCP_PORT=3306-DENABLED_LOCAL_INFILE=1-DWITH_PARTITION_STORAGE_ENGINE=1-DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci

make && make install

如果在上面的编译报错,Could NOT find Curses (missing: CURSES_LIBRARY CURSES_INCLUDE_PATH),则使用下面的编辑代码:

cmake -DCURSES_LIBRARY=/usr/lib/libncurses.so -DCURSES_INCLUDE_PATH=/usr/include -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DSYSCONFDIR=/etc -DWITH_MYISAM_STORAGE_ENGINE=1-DWITH_INNOBASE_STORAGE_ENGINE=1-DWITH_MEMORY_STORAGE_ENGINE=1-DWITH_READLINE=1-DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock -DMYSQL_TCP_PORT=3306-DENABLED_LOCAL_INFILE=1-DWITH_PARTITION_STORAGE_ENGINE=1-DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci

要很长时间的等待,我虚拟机中安装是双核2G内存,花了20分钟左右的。

另外还可能遇到下面的错误:

1.

yum install libevent* libtool* autoconf* libstd* ncurse* bison* openssl*

报错:

libevent2-devel conflicts with libevent-devel-1.4.13-4.el6.x86_64

则执行:

yum install libevent2 libtool* autoconf* libstd* ncurse* bison* openssl*

2.

查看 ls /usr/lib/libncurses.so

如果找不到,则

find / -name ‘libncurses.so’

我找到的文件如下:

/usr/lib64/libncurses.so

增加快捷方式

ln -s /usr/lib64/libncurses.so /usr/lib/libncurses.so

5.配置mysql

groupadd mysql

useradd -g mysql mysql

chown -R mysql:mysql /usr/local/mysql

初始化配置

cd /usr/local/mysql

scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql

配置自启动和启动mysql

cp support-files/mysql.server /etc/init.d/mysql

chkconfig mysql on

service mysql start

配置PATH

vi /etc/profile

#在文件末尾添加

PATH=/usr/local/mysql/bin:$PATH

export PATH

#保存退出,生效配置

source /etc/profile

登陆mysql 并设置root密码

mysql -uroot

mysql> SET PASSWORD =PASSWORD('123456');

设置mysql可以远程访问

mysql> GRANT ALL PRIVILEGES ON *.* TO'root'@'%'IDENTIFIED BY'123456'WITH GRANT OPTION;

执行下边的命令,使上边的命令生效

flush privileges;

如果是远程,配置可以远程访问,配置防火墙,允许3306端口

/sbin/iptables -I INPUT -p tcp --dport3306-j ACCEPT

/etc/rc.d/init.d/iptables save

6.数据库定时备份:

mkdir /backup

chmod777-R /backup

vim /backup/mysql_backup.sh

写入如下内容:-p引号里面是数据库的密码,erp是备份的数据库名字

#!/bin/bash

date=$(date +%Y%m%d)

/usr/local/mysql/bin/mysqldump -h localhost -uroot -p'Ddsd#$#2s$!s4343%$^&s'erp > /backup/databases-$date.sql

设置CRON,定时备份:

crontab -e

0006* * * /bin/bash /backup/mysql_backup.sh
