190119 12:55:54 [ERROR] mysqld got signal 11 ;解决办法：
修改/etc/my.cnf配置文件：
添加参数：
innodb_force_recovery = 6 （此项由1—6个级别一次往上修改参数在失败的情况下）
innodb_purge_threads = 0
整体配置如下：
[mysqld]
innodb_force_recovery=6
innodb_purge_threads = 0
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
