一、前言

前几篇博客中我们讲解了MySQL5.1与MySQL5.5之间的性能差异，MySQL5.5的性能有明显的提升，特别是对多核CPU的支持与TPS性能的提升。在这篇博客中我们将主要讲解MySQL 5.1.73升级为MySQL 5.5.35。下面我们继续……

二、概述

1.安装yum源

[root@node6 src]# wget http://mirrors.hustunique.com/epel/6/x86_64/epel-release-6-8.noarch.rpm
[root@node6 src]# rpm -ivh epel-release-6-8.noarch.rpm

2.同步时间

2
3
[root@node6 src]# yum install -y ntp
[root@node6 src]# ntpdate 202.120.2.101
[root@node6 src]# hwclock –w

3.安装mysql 5.1依赖包

1
[root@node6 mysql-5.1.73]# yum -y install ncurses ncurses-devel

4.安装mysql5.5依赖包

1
[root@node6 ~]# yum install -y autoconf* automake* zlib* libxml* ncurses-devel* libgcrypt* libtool* openssl*

5.安装cmake

1
[root@node6 ~]# yum install -y cmake

三、安装MySQL 5.1.73

1.编译并安装mysql5.1

[root@node6 mysql-5.1.73]# tar xf mysql-5.1.73.tar.gz
[root@node6 mysql-5.1.73]# cd mysql-5.1.73
[root@node6 mysql-5.1.73]# ./configure --prefix=/usr/local/mysql --localstatedir=/data/mysql --enable-assembler --with-client-ldflags=-all-static --with-mysqld-ldflags=-all-static --with-pthread --enable-static --with-big-tables --without-ndb-debug --with-charset=utf8 --with-extra-charsets=all --without-debug --enable-thread-safe-client --enable-local-infile --with-plugins=max

This version of MySQL Cluster is no longer maintained.
Please use the separate sources provided forMySQL Cluster instead.
See http://dev.mysql.com/doc/refman/5.1/en/mysql-cluster.html
formoredetails.
Thank you forchoosing MySQL!
Remember to check the platform specific part of the reference manual
forhints about installing MySQL on your platform.
Also have a lookat the files inthe Docs directory.

到这里我们编译配置就完成了，下面我们编译并安装。

1
[root@node6 mysql-5.1.73]# make && make install

注，编译与安装时间比较长请大家耐心等待，当然会看各位博友机器的配置，相对来说配置越好，相对的编译与安装时间相对就少。

2.创建数据目录并授权

[root@node6 mysql-5.1.73]# mkdir -pv /data/mysql
mkdir: 已创建目录 "/data/mysql"
[root@node6 mysql-5.1.73]# useradd mysql
[root@node6 mysql-5.1.73]# chown mysql.mysql /data/mysql/
[root@node6 mysql-5.1.73]# ll /data/
总用量 20
drwx------. 2 root  root  16384 8月  17 18:42 lost+found
drwxr-xr-x. 2 mysql mysql  4096 1月   4 16:10 mysql

3.为mysql提供配置文件

1
2
[root@node6 mysql-5.1.73]# cp support-files/my-huge.cnf /etc/my.cnf
cp：是否覆盖"/etc/my.cnf"？ y

4.简单修改一下配置文件

[root@node6 mysql-5.1.73]# vim /etc/my.cnf
[client]
default-character-set= utf8
[mysqld]
default-character-set= utf8
datadir        = /data/mysql

5.提供启动脚本

[root@node6 mysql-5.1.73]# cp support-files/mysql.server /etc/init.d/mysqld
[root@node6 mysql-5.1.73]# chmod +x /etc/init.d/mysqld
[root@node6 ~]# chkconfig mysqld --add
[root@node6 ~]# chkconfig mysqld on

OK
To start mysqld at boot timeyou have to copy
support-files/mysql.server to the right place foryour system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To doso, start the server, thenissue the following commands:
/usr/local/mysql//bin/mysqladmin-u root password 'new-password'
/usr/local/mysql//bin/mysqladmin-u root -h node6.test.com password 'new-password'
Alternatively you can run:
/usr/local/mysql//bin/mysql_secure_installation
whichwill also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended forproduction servers.
See the manual formoreinstructions.
You can start the MySQL daemon with:
cd/usr/local/mysql/; /usr/local/mysql//bin/mysqld_safe&
You can testthe MySQL daemon with mysql-test-run.pl
cd/usr/local/mysql//mysql-test; perl mysql-test-run.pl
Please report any problems with the /usr/local/mysql//scripts/mysqlbugscript!

注，从上面的内容中我们看到了几个警告，我们查看一下。

从上面的警告可以看到，--default-character-set、--skip-locking选项已经过时，建议使用--character-set-server、--skip-external-locking。

7.查看一下初始化目录

[root@node6 data]# ls /data/mysql/
mysql  mysql-bin.000001  mysql-bin.000002  mysql-bin.index  test

| count(*) |
+----------+
|       20 |
+----------+
1 row inset(0.33 sec)

四、升级为MySQL 5.5.35

1.升级前准备（查看MySQL 5.1相关参数，具体如下）

(1).安装目录

1
[root@node6 ~]# /usr/local/mysql

(2).配置文件

1
[root@node6 ~]# /etc/my.cnf

(3).数据目录

1
[root@node6 ~]# /data/mysql

(4).启动脚本

1
[root@node6 ~]# /etc/init.d/mysqld

(5).其它参数

  • 输出mysql的man手册至man命令的查找路径

  • 输出mysql的头文件至系统头文件路径/usr/include

  • 输出mysql的库文件给系统库查找路径

  • 修改PATH环境变量，让系统可以直接使用mysql的相关命令

2.升级方式

  • 直接将MySQL5.5安装目录覆盖正在运行的Mysql目录（我们这里演示使用的方式）

  • 将MySQL5.5安装到其它目录中，如/usr/local/mysql5

3.备份所有数据库

1
[root@node6 ~]# mysqldump -uroot -p123456 test -l -F '/tmp/test.sql'

  • -l 锁定

  • -F 即flush logs，可以重新生成新的日志文件，当然包括log-bin日志

4.备份安装目录

1
[root@node6 ~]# tar czvf mysql_5.1.73_full.tar.gz /usr/local/mysql

5.备份数据目录

1
[root@node6 ~]# tar czvf mysql_5.1.73_data_full.tar.gz /data/mysql

6.备份配置文件

1
[root@node6 ~]# cp /etc/my.cnf ./

7.关闭mysql

1
2
[root@node6 ~]# service mysqld stop 
Shutting down MySQL.. SUCCESS!

好了，到这里我们准备工作就完成了。下面我们来升级到MySQL 5.5.35……

8.升级mysql 5.5.35

[root@node6 mysql-5.5.35]# make && make install

9.删除原有的mysql5.1的配置文件

1
[root@node6 mysql-5.5.35]# rm -rf /etc/my.cnf

10.提供新的配置文件

1
[root@node6 mysql-5.5.35]# cp support-files/my-huge.cnf /etc/my.cnf

11.修改一下配置文件

1
2
[mysqld] 
datadir         = /data/mysql

注，只增加一行指定数据数据/data/mysql。

12.尝试重新启动一下
