前几天公司的一个项目组的同事反应说公司内部的一台Linux服务器上的MySQL没有InnoDB这个引擎,我当时想应该不可能啊,MySQL默认应该就已经安装了这个引擎的吧,于是上服务器去看了看,发现还真没有,于是putty到服务器上,show engines看了一下:
+------------+---------+
| Engine | Support |
+------------+---------+
| CSV | YES |
| MRG_MYISAM | YES |
| MEMORY | YES |
| MyISAM | DEFAULT |
+------------+---------+
列表中没有InnoDb,第一反应是不是安装MySQL的时候没有编译InnoDb呢?但心想MySQL应该是自带了的,但google发现有网友说因为InnoDb是以插件的方式加载到MySQL中的,所以可以直接使用install plugin innodb soname 'ha_innodb.so'来启用InnoDB,但首先我们需要查看一下是否已经编译InnoDb:
mysql> show plugins;但是发现连插件里面都没有,这下可以确定是没有编译了,于是决定对MySQL重新编译,当然编译前请先备份所有数据库,以免造成数据丢失。

[root@192.168.1.1]# mysqldump --all-database -u root -p > /data0/www/1.sql
[root@192.168.1.1]# mysql-5.1.60]#screen -S stou
[root@192.168.1.1]# mysql-5.1.60]#automake --force --add-missing
[root@192.168.1.1]# mysql-5.1.60]#./configure --prefix=/usr/local/mysql/ --with-plugins=innobase
wdcp下安装:
[root@192.168.1.1]# mysql-5.1.60]#./configure --prefix=/usr/local/mysql/ --with-plugins=innobase --with-charset=gbk --with-collation=gbk_chinese_ci
但是最后却出现了以下错误:
mysql.cc:1049: error: expected constructor, destructor, or type conversion before '*' tokenGoogle一下发现不少人都有这个问题,其实解决这个问题只需要在configure前执行一次:
mysql.cc: In function 'int not_in_history(const char*)':
mysql.cc:2427: error: 'HIST_ENTRY' was not declared in this scope
mysql.cc:2427: error: 'oldhist' was not declared in this scope

[root@192.168.1.1]# make clean然后再重复./configure --prefix=/usr/local/mysql/ --with-plugins=innobase和make这个步骤就可以了,然后再:
[root@192.168.1.1]# make install
[root@192.168.1.1]# service mysqld restart
[root@192.168.1.1]# mysql -u root -p
mysql> show engines;
+------------+---------+
| Engine | Support |

InnoDB启用成功!
