修改mysql配置文件my.cnf启用innodb之后mysql起不来

czlceo

众大神帮帮忙

LNMP按安装包，我修改my.cnf


# 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

这样之后mysql重启就起不来了
报错
Starting MySQL.Manager of pid-file quit without updating fi[FAILED]

该怎么办?
