mysqldump: Got error: 1135: Can't create a new thread (errno 11); if you are not out of available memory, you can consult the manual for a possible OS-dependent bug when trying to connect 解决办法

在进行数据库备份的时候发现服务器报 mysqldump: Got error: 1135: Can't create a new thread (errno 11); if you are not out of available memory, you can consult the manual for a possible OS-dependent bug when trying to connect 错误

，出现原因是服务器的连接数太多了，当mysql的连接数大于默认数值（1024）时，就会出现这个错误，需要增加服务器的最大连接数，方法如下：

打开 /etc/security/limits.conf

增加两行参数:

* soft nofile 65535

* hard nofile 409600

为了避免重启服务器可以在命令行中执行：

ulimit -u 65535

验证下mysql的最大连接数

cat /proc/`pidof mysqld`/limits | egrep "(processes|files)"

Max processes 65535 65535 processes

Max open files 65535 409600 files
