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]# cd mysql-5.5.35
[root@node6 mysql-5.5.35]# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DSYSCONFDIR=/etc -DMYSQL_DATADIR=/data/mysql -DMYSQL_TCP_PORT=3306 -DMYSQL_UNIX_ADDR=/tmp/mysqld.sock -DMYSQL_USER=mysql -DEXTRA_CHARSETS=all -DWITH_READLINE=1 -DWITH_SSL=system -DWITH_EMBEDDED_SERVER=1 -DENABLED_LOCAL_INFILE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1
[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

datadir         = /data/mysql

注,只增加一行指定数据数据/data/mysql。
