linux 安装mysql5.6

linux 安装mysql5.6
Linux:Centos

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/deta...

或者在百度网盘下载:https://pan.baidu.com/s/1kVwRD2Z

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;

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 --dport 3306 -j ACCEPT  
/etc/rc.d/init.d/iptables save

6.数据库定时备份:

mkdir /backup  
chmod 777 -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   
00 06 * * * /bin/bash /backup/mysql_backup.sh
