1）关闭mysqld服务
2）修改my.ini（linux下是my.cnf）将skip-innodb这行注释掉或删掉
3) 保存后重启mysqld服务

你是如何安装的？

从你的 show 里看应该是安装了引擎的，只是被禁用了。
你可以用 ps awux 来看看 mysqld/mysqld_safe 的命令行用的是哪一个 my.cnf，如果没有指定会是使用的默认的 /etc/my.cnf，否则可能在启动参数中指定另外的 my.cnf 路径及文件名，或者在命令行参数里就指定了 skip 选项等。所以建议看看命令行的参数先。
#6
能show 出来，表示 InnoDB 已经被安装好了，只是被禁用了吧！
看看my.cnf里面有没有skip类似的设置！

mysql 能够正常使用，mysql 配置没有问题。
从mysql> show engines;显示的信息可以确认innnodDB已经安装 ，只是被禁用了。

# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# change in this file to the variables' values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id = 2
#
# The replication master for this slave - required
#master-host = <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user = <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password = <password>

# optional - defaults to 3306

估计这个就是Innodb没有开启的问题。

检查一下你的目录中
ibdata1
ib_logfile0
ib_logfile1
这些文件情况，不行就把这三个文件删除（先备份一下）
