将redis 2.4.14升级为redis 2.6.14，命令"service redis start“始终挂起

Question

我之前安装了redis2.4.14。昨天，我得到了redis2.6.14，并直接"cd 2.6.14/src；make && make“。我移除了redis的dump.rdb和redis.log。我还将配置文件升级到2.6.14。当我安装redis-2.4.14时，我添加了redis来服务。我执行命令"service redis start"，但它总是挂起没有"ok“信息。

[tys@localhost bin]# service redis start
Starting redis-server: 

我可以正常地使用红葡萄酒

[tys@localhost redis]# redis-cli
redis 127.0.0.1:6379> set name tys
OK
redis 127.0.0.1:6379> get name
"tys"

但如果我输入"ctrl + c“或"ctrl + z"，"redis-cli”将继续。

当我重新启动系统时，linux引导进程挂在“启动redis-server”(抱歉，我太“年轻”，不能发布映像)。https://groups.google.com/forum/#!topic/redis-db/iQnlyAAWE9Y)

但我能做到这是个虚拟机。redis.log中没有错误。

这是我的redis init.d脚本：

Answer 1

我和Josiah在https://groups.google.com/forum/#!forum/redis-db的帮助下重新设计了它。

在我的redis.conf中，它是"daemonize no“。在我切换到"daemonize“之后，Redis就开始了。

Answer 2

版本3.0.1 @ CentOS 6.6 --同样的问题。

尝试使用两个不同的init脚本。

'daemonize yes‘解决了这个问题！
