Question

在我使用CentOS 6.6运行的Docker容器中，我收到以下错误：

2014/12/25 15:09:07 [alert] 319#0: *2030 socket() failed (24: Too many open files) while connecting to upstream, client: 127.0.0.1, server: test.org.au, request: "GET / HTTP/1.0", upstream: "http://127.0.0.1:80/", host: "127.0.0.1"
2014/12/25 15:09:07 [crit] 319#0: *2030 open() "/usr/share/nginx/html/50x.html" failed (24: Too many open files), client: 127.0.0.1, server: test.org.au, request: "GET / HTTP/1.0", upstream: "http://127.0.0.1:80/", host: "127.0.0.1"

我在主机上运行的Docker版本是1.3.3

我试图在Docker容器中设置ulimit，但我得到了以下内容：

[root@test ~]# sysctl -p
error: "Read-only file system" setting key "net.ipv4.ip_forward"
error: "Read-only file system" setting key "net.ipv4.conf.default.rp_filter"

error: "Read-only file system" setting key "kernel.shmmax"
error: "Read-only file system" setting key "kernel.shmall"
error: "Read-only file system" setting key "fs.file-max"

当我尝试在浏览器中查看网址时，我收到500内部服务器错误。

我也在运行LEMP（Nginx，MySQL和PHP-FPM）堆栈。

有人对这个问题有一些建议吗？

您可以增加将ulimit -n 65536添加到文件/etc/init.d/docker的泊坞窗服务的打开文件限制。

socket失败打开文件太多错误Docker
