kill掉部分进程
//查看进程# ps -ef//把ps的查询结果通过管道给grep查找包含特定字符串的进程。管道符“|”用来隔开两个命令，管道符左边命令的输出会作为管道符右边命令的输入# ps -ef | grep firefox smx 1827 1 4 11:38 ? 00:27:33 /usr/lib/firefox-3.6.18/firefox-bin smx 12029 1824 0 21:54 pts/0 00:00:00 grep --color=auto firefox//杀了火狐的进程 # kill -s 9 1827我的解决办法：
1.在/etc/中开启InnoDB
2.关闭nginx和php
/etc//nginx stop
/etc//php-fpm stop
3.重启mysql
/etc//mysqld restart
/etc//nginx start
/etc//php-fpm start
