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

mysql> show plugins;

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 tables

innodb_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
