Linux Apache配置

本文介绍Apache不能启动提示“nospaceleftondevice”解决办法，希望对于初学Apache服务器相关的朋友有帮助，更多Apache安装、配置、报错处理等资源请本站内搜索。

1) 问题

Apache启动失败；

错误日志提示如下：No space left on device: mod_jk: could not create jk_log_lock Configuration Failed

2) 解决步骤

1）切换到root账号，先用下面的这个命令检查一下哪个用户的信号量比较多：

#ipcs -a

2）然后关掉那个用户的apache，用下面这个命令删除信号量（注意修改用户名）：

#ipcs -s | grep username| gawk '{ print $2 }' | xargs -n 1 ipcrm sem

3）最后重启Apache

问题解决。

3) 操作实例

a) 启动失败

[[email protected] init.d]# ./httpd start

Starting httpd: [FAILED]

b) 查看日志

[[email protected] logs]# tail -f error_log

[Thu Apr 12 02:21:21 2012] [crit] (28)No space left on device: mod_jk: could not create jk_log_lock

Configuration Failed

c) 检查信号量

[[email protected] init.d]# ipcs -a

发现daemon用户占用信号量较多。

d) 删除信号量

注意用户名已换为daemon。

[[email protected] init.d]# ipcs -s | grep daemon| gawk '{ print $2 }' | xargs -n 1 ipcrm sem

resource(s) deleted

e) 再检查信号量

[[email protected] init.d]# ipcs -a
