今天访问自己的博客，发现文章排序不正确了，知道是读数据库了，没有走ES！~然后就以为是ES出错了，后来登陆到服务器上面，想看看是怎么了，结果发现在按tab 进行命令提示时，总是报错 cannot create temp file for here-document: No space left on device。
经过在网上查询这个错误，发现这个错误是磁盘满了造成的。
可以通过命令:
df -h
来查看一下当前磁盘的空间，果然满了。我这时的磁盘空间状态：
[hhh@iZ2 var]$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/vda1 40G 38G 0 100% /
devtmpfs 486M 0 486M 0% /dev
tmpfs 497M 0 497M 0% /dev/shm
tmpfs 497M 50M 447M 11% /run
tmpfs 497M 0 497M 0% /sys/fs/cgroup
tmpfs 100M 0 100M 0% /run/user/1001
我去，咋回事呢？一时想不到原因了。
这里看到有人说先用top 追踪一下，看看系统资源情况（但是我并未发现什么异常）：

可以看到有两个东西：
21G /tmp/systemd-private-59d9b85992c748279db6d9a3a279b764-php-fpm.service-T8lL7D/tmp
21G /tmp/systemd-private-59d9b85992c748279db6d9a3a279b764-php-fpm.service-T8lL7D
说实话，这俩东西是啥，我还真不知道啊。参考这个文章（https://www.cnblogs.com/lihuobao/p/5624071.html） ， 我大概看了一下，就是为了安全。但是应该是设置了这个人选项，应该会自动清理这个临时文件，为啥我的没有清理呢！好奇怪啊。。。。
望看到这篇文章并知道为啥的小伙伴能通过邮箱告知我哈！~~多谢。。。 如我日后知道答案了，我再写进来哈。。。
这边我的解决办法是先重启一下php-fpm 试试，看看是不是stop掉这个服务，然后在重启服务，它会自己清理临时文件。
systemctl stop php-fpm
systemctl start php-fpm
df -h
Filesystem Size Used Avail Use% Mounted on
/dev/vda1 40G 18G 21G 46% /
devtmpfs 486M 0 486M 0% /dev
tmpfs 497M 0 497M 0% /dev/shm
tmpfs 497M 50M 447M 11% /run
tmpfs 497M 0 497M 0% /sys/fs/cgroup
tmpfs 100M 0 100M 0% /run/user/1001
果然，还真是自己清理掉了。这样我文章列表排序也正确了，并不是ES的问题。
