现在自己解决了..是因为使用wwwroot\domian\tmp下面产生了94G的临时文件.. 导致磁盘100%. 删掉tmp就好了. 另外请问管理员 wwwroot\domian\tmp是什么?为什么会产生如此大的临时文件 狠狠的扇了自己几个耳光.. 就因为这个问题. 纠结了整整一天. 全部注意力全几种到了mysql..到头来和MYSQL无关.. 以后排错得全方位排查了. 以下问题已解决 ============================================================= 今天网站502 bad gateway. 简要检查下无果.遂直接重启服务器.结果mysql无法启用.百度谷歌几个小时无果.特向各位前辈请教. 现在唯一的奢求是能备份出数据库.. 重装mysql也无妨. # mysql restart 错误如下 ============================================================= ERROR! MySQL server PID file could not be found! Starting MySQL.. ERROR! The server quit without updating PID file (/usr/local/mysql/data/AY1405191822541604eaZ.pid). #mysql -u root -p 错误如下: ============================================================= ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) # mysqld_safe & 错误如下 ============================================================= [1] 10781 140612 15:00:42 mysqld_safe Logging to '/usr/local/mysql/data/AY1405191822541604eaZ.err'. 140612 15:00:42 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data 140612 15:00:43 mysqld_safe mysqld from pid file /usr/local/mysql/data/AY1405191822541604eaZ.pid ended /tmp/mysql.sock 不存在此文件.. >ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock 无效 后发现mysql也不存在mysql.sock.. 于是#find -name mysql.sock 发现mysql.sock丢失 于是放弃 想用mysqldump 导出数据后重装 # mysqldump -u root -p dbname> dbname.sql mysqldump: Got error: 2002: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) when trying to connect /etc/my.cnf 配置如下: ============================================================= [client] port = 3306 socket = /tmp/mysql.sock [mysqld] default-storage-engine = MyISAM port = 3306 socket = /tmp/mysql.sock skip-external-locking key_buffer_size = 16M max_allowed_packet = 1M table_open_cache = 64 sort_buffer_size = 512K net_buffer_length = 8K read_buffer_size = 256K read_rnd_buffer_size = 512K myisam_sort_buffer_size = 8M log-bin = mysql-bin binlog_format = mixed server-id = 1 [mysqldump] quick [mysql] no-auto-rehash [myisamchk] key_buffer_size = 20M sort_buffer_size = 20M read_buffer = 2M write_buffer = 2M [mysqlhotcopy] interactive-timeout /usr/local/mysql/data/AY1405191822541604eaZ.err 错误日志如下: ============================================================= 140612 14:55:47 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data 140612 14:55:47 InnoDB: The InnoDB memory heap is disabled 140612 14:55:47 InnoDB: Mutexes and rw_locks use GCC atomic builtins 140612 14:55:47 InnoDB: Compressed tables use zlib 1.2.3 140612 14:55:47 InnoDB: Initializing buffer pool, size = 128.0M 140612 14:55:47 InnoDB: Completed initialization of buffer pool 140612 14:55:47 InnoDB: highest supported file format is Barracuda. 140612 14:55:47 InnoDB: Waiting for the background threads to start 140612 14:55:48 InnoDB: 5.5.34 started; log sequence number 1595685 06:55:48 UTC - mysqld got signal 11 ; This could be because you hit a bug. It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail. key_buffer_size=16777216 read_buffer_size=262144 max_used_connections=0 max_threads=151 thread_count=0 connection_count=0 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 134092 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. Thread pointer: 0x0 Attempting backtrace. You can use the following information to find out where mysqld died. If you see no messages after this, something went terribly wrong... stack_bottom = 0 thread_stack 0x40000 /usr/local/mysql/bin/mysqld(my_print_stacktrace+0x2e)[0x75a0ce] /usr/local/mysql/bin/mysqld(handle_fatal_signal+0x41a)[0x64f57a] /lib64/libpthread.so.0(+0xf710)[0x7ff321f6a710] The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains information that should help you find out what is causing the crash. 140612 14:55:48 mysqld_safe mysqld from pid file /usr/local/mysql/data/AY1405191822541604eaZ.pid ended  点赞，加油！ (1分)

/home/wwwroot/domain/tmp/是Php程序调用期间产生的临时文件
如果不行的话直接删，新建文件，授权不可写不可读
