drupal7正式发布了,下载了一下,安装时候提示我错误,安装不了
Syntax error or access violation: 1286 Unknown table engine 'InnoDB'
原来是我的mysql里面,根本没有innodb存储引擎。进去后我们可以用 show engines;或者show plugins;来查看

解决方法1(推荐使用):在configure的时候加上--with-plugins=innobase 如果要添多个插件,请用半角逗号隔开
如果何配置呢,其实将copy到/usr/local/mysql/my.cnf配置文件中[mysqld]下面有关innodb配置前面的#去掉就可以了。这是默认配置,可以根据个人需要进行修改
# Uncomment the following if you are using InnoDB tablesinnodb_data_home_dir = /usr/local/mysql/var/
innodb_data_file_path = ibdata1:10M:autoextend
innodb_log_group_home_dir = /usr/local/mysql/var/
# You can set .._buffer_pool_size up to 50 - 80 %
# of RAM but beware of setting memory usage too high
innodb_buffer_pool_size = 16M
innodb_additional_mem_pool_size = 2M
# Set .._log_file_size to 25 % of buffer pool size
innodb_log_file_size = 5M
innodb_log_buffer_size = 8M
innodb_flush_log_at_trx_commit = 1
innodb_lock_wait_timeout = 50
解决方法2:
如果你安装的时候忘记了添加innodb,又不想重新编辑mysql来添加,这样也没有关系,innodb就是一个插件,安装好mysql后也是可以添加的。
1,查看一下,mysql配置是不是支持动态添加插件
mysql> show variables like "have_%";+----------------------+-------+
| Variable_name | Value |
+----------------------+-------+
| have_compress | YES |
| have_crypt | YES |
| have_csv | YES |
| have_dynamic_loading | YES | //在这里是YES表示是支持的
如果是no呢,就不太好办,因为have_dynamic_loading是只读变量,
mysql> set have_dynamic_loading=1;
ERROR 1238 (HY000): Variable 'have_dynamic_loading' is a read only
variable
不过一般情况下都是YES,
2,添加插件
mysql> INSTALL PLUGIN INNODB SONAME 'ha_innodb.so'; //提示打不开文件,没有权限ERROR 1126 (HY000): Can't open shared library '/usr/local/mysql/lib/mysql/plugin/ha_innodb.so' (errno: 13 cannot restore segment prot after reloc: Permission denied)
上面报没有权限错误,搞得我很郁闷,解决办法如下:
root@ubuntu:/usr/local/mysql# find . -type d -print |grep -i plugin //查看一下插件目录对不对./lib/mysql/plugin
root@ubuntu:/usr/local/mysql# chcon -t texrel_shlib_t /usr/local/mysql/lib/mysql/plugin/ha_innodb.so
chcon: 部分关联无法应用于文件“/usr/local/mysql/lib/mysql/plugin/ha_innodb.so”
用chcon也报错,我查一下是因为我没有安装selinux
root@ubuntu:/usr/local/mysql# whereis
selinux
selinux:
selinux我根本没有安装,如果个人用,这个也不需要,没办法装一下,装完后chcon就不报错了。
安装以下几个
mysql> install plugin INNODB soname "ha_innodb.so";mysql> install plugin INNODB_TRX soname "ha_innodb.so";
mysql> install plugin INNODB_LOCKS soname "ha_innodb.so";
mysql> install plugin INNODB_LOCK_WAITS soname "ha_innodb.so";
mysql> install plugin INNODB_CMP soname "ha_innodb.so";
mysql> install plugin INNODB_CMP_RESET soname "ha_innodb.so";
mysql> install plugin INNODB_CMPMEM soname "ha_innodb.so";
mysql> install plugin INNODB_CMPMEM_RESET soname "ha_innodb.so"
安装好后,在用 show engines;或者show plugins;来查看
mysql> show plugins;+---------------------+--------+--------------------+---------+---------+

配置和方法一一样,第二种方法比较麻烦,不推荐使用。
