今天真的是遇到的大麻烦了。本来想在服务器上再搭建一个网站的，结果不知道弄了哪里，导致了mysql数据库直接无法启动了。网上找遍了所有方法都没有解决。最后还是在一个博客上找到的解决方法。于是记录一下，方便下次遇到这个问题的时候不用折腾这么久。
语句如下：
我当时就用了这一条语句就OK了，之后还翻过别的资料，有些人还说要做下面这些东西，我也没认真看，先都copy一份吧，下次出问题再回头来翻这里看看：
首先、检查宝塔面板MySQL无法启动（自动停止）出错原因：
wget -O sql-repair.sh http://download.bt.cn/install/sql-repair.sh && sh sql-repair.sh
然后、宝塔面板 /etc/my.cnf 的设置内容（MySQL 5.6 my.cnf 的设置内容）：
[client]
#password = your_password
port = 3306
socket = /tmp/mysql.sock
[mysqld]
port = 3306
socket = /tmp/mysql.sock
datadir = /www/server/data
default_storage_engine = MyISAM
#skip-external-locking
#loose-skip-innodb
key_buffer_size = 8M
max_allowed_packet = 1M
table_open_cache = 32
sort_buffer_size = 256K
net_buffer_length = 4K
read_buffer_size = 128K
read_rnd_buffer_size = 256K
myisam_sort_buffer_size = 4M
thread_cache_size = 4
query_cache_size = 4M
tmp_table_size = 8M
sql-mode=NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTIO
#skip-networking
#skip-name-resolve
max_connections = 500
max_connect_errors = 100
open_files_limit = 65535
log-bin=mysql-bin
binlog_format=mixed
server-id = 1
expire_logs_days = 10
default_storage_engine = InnoDB
innodb_data_home_dir = /www/server/data
innodb_data_file_path = ibdata1:10M:autoextend
innodb_log_group_home_dir = /www/server/data
innodb_buffer_pool_size = 16M
innodb_additional_mem_pool_size = 2M
innodb_log_file_size = 5M
innodb_log_buffer_size = 8M
innodb_flush_log_at_trx_commit = 1
innodb_lock_wait_timeout = 50
[mysqldump]
quick
max_allowed_packet = 16M
[mysql]
no-auto-rehash
[myisamchk]
key_buffer_size = 20M
sort_buffer_size = 20M
read_buffer = 2M
write_buffer = 2M
[mysqlhotcopy]
interactive-timeout
最后、用下面的命令代码生效一下：
/www/server/mysql/scripts/mysql_install_db --defaults-file=/www/server/mysql/my.cnf --basedir=/www/server/mysql --datadir=/www/server/data/ --user=mysql
一共也就两条语句。
