我运行的是 centOs 6.3，我在本地机器上通过 remi 存储库安装了 redis-server。我可以运行 redis cli。
但是当我尝试通过 php 脚本连接时，我得到了
fsockopen(): unable to connect to 127.0.0.1:6379
我尝试在禁用 IPtables 后运行它，但那对我来说仍然不起作用。
这是运行时的 iptables 规则
target prot opt source destination
ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED

Chain FORWARD (policy ACCEPT)
target prot opt source destination
REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited
我也尝试运行以下命令，但没有成功。
setsebool -P httpd_can_network_connect 1

答案1
问题解决了@cjc 说 redis 没有监听 127.0.0.1 ip。在我的 predis 配置中，我提供了 0.0.0.0 作为 ip，它就开始工作了。
