宝塔上就装了两个wordpress 
隔三差五就发现redis自动关闭 
nginx也关闭，重启报错 
Nginx配置规则错误: 
nginx version: nginx/1.28.0 
nginx: the configuration file /www/server/nginx/conf/nginx.conf syntax is ok 
nginx: [emerg] mkdir() “/dev/shm/nginx-cache/网址” failed (2: No such file or directory) 
nginx: configuration file /www/server/nginx/conf/nginx.conf test failed 
然后服务器是在线的，但是宝塔登不上去，必须要重启，就莫名其妙的错误
