我有一个nodeBB安装,它依赖Redis作为数据存储.它只是一个测试安装,而我解决任何问题. Redis实例保持了几天,但随后在日志中出现以下错误：
3693:C 01 Dec 03:34:22.056 # Error moving temp DB file on the final destination: Operation not permitted 7089:M 01 Dec 03:34:22.155 # Background saving error 7089:M 01 Dec 03:34:28.067 * 1 changes in 900 seconds.

使用following method使用以下说明(默认的yum包太旧)使用following method在Centos 6.7上以root身份安装Redis：
tar xzf redis-3.0.x.tar.gz cd redis-3.0.1 make make test make install cd utils chmod +x install_server.sh ./install_server.sh
在/etc/redis/6379.conf中设置的工作目录：
# The filename where to dump the DB dbfilename dump.rdb # The working directory. # # The DB will be written inside this directory,with the filename specified # above using the 'dbfilename' configuration directive. # # The Append Only File will also be created inside this directory. # # Note that you must specify a directory here,not a file name. dir /var/lib/redis/6379
任何人都可以建议导致这种情况的原因以及如何最好地解决问题？ Redis会在哪里尝试保存临时文件,用户会使用哪些权限以及哪些权限可以安全地解决此问题？
同样感兴趣的是一种监控Redis实例的免费方法,因此我知道它是否/何时会崩溃.

检查是否启用了sestatus的SELinux.如果启用(推荐的东西),请通过setenforce 0将其置于许可模式.
之后再次检查您的系统,我猜错误将消失,检查安全日志以查看SELinux阻止了什么,在您的策略中启用它并将SELinux重新置于强制模式(当然,如果您想让您的服务器受到保护)作者：SELinux)
