错误集合

错误 1

 

The program package-cleanup is found in the yum-utils package

解决方法:

# yum clean all
# rpm --rebuilddb
# yum update

 

使用解决方法仍然报错，根据错误信息 检查 /etc/yum.conf 确保 没有这行 exclude=*.i386 *.i586 *.i686

结束

原来使用yum 安装软件时会自动安装上两个版本的，xxx.i386 与 xxx.x86_64 ，由于我使用的基本是64 位操作系统，所以在 /etc/yum.conf 屏蔽安装所有 i386 软件包，造成了这个错误。

 

错误2

login: PAM [dlerror: /lib/security/pam_limits.so: cannot open shared object
file: No such file or directory]

解决方法

vim /etc/pam.d/login
修改

"session    required     /lib/security/pam_limits.so"

为
"session    required     /lib64/security/pam_limits.so"

重启

 错误3

 kernel: nf_conntrack: table full, dropping packet.

解决方法

rhel5/centos5

在/etc/sysctl.conf中加入：
net.ipv4.netfilter.ip_conntrack_max = 655350
net.ipv4.netfilter.ip_conntrack_tcp_timeout_established = 1200

立即生效
sysctl -p

统计
wc -l /proc/net/ip_conntrack
34546 /proc/net/ip_conntrack

rhel6/centos6

在/etc/sysctl.conf中加入：
net.nf_conntrack_max = 100000

立即生效
sysctl -p

统计
wc -l /proc/net/nf_conntrack
51962 /proc/net/nf_conntrack

扩展

kernel 用 ip_conntrack 模块来记录 iptables 网络包的状态，并保存到 table 里（/proc/net/ip_conntrack|/proc/net/nf_conntrack），
如果网络状况繁忙，比如高连接，高并发连接等会导致逐步占用这个 table 可用空间，
一般这个 table 很大不容易占满并且可以自己清理，table 的记录会一直呆在 table 里占用空间直到源 IP 发一个 RST 包，
但是如果出现被攻击、错误的网络配置、有问题的路由/路由器、有问题的网卡等情况的时候，就会导致源 IP 发的这个 RST 包收不到，
这样就积累在 table 里，越积累越多直到占满，满了以后 iptables 就会丢包，出现外部无法连接服务器的情况。

知道问题就好办了，要么增加 table 容量以便能记录更多的连接信息（会消耗一点内存），要么就卸载 ip_conntrack 模块。

 

错误6 (编译 nrpe for nagios)

make[1]: Leaving directory `/root/nagios/nrpe-2.13/src'

*** Compile finished ***

If the NRPE daemon and client compiled without any errors, you
can continue with the installation or upgrade process.

原因

在/usr/local/目录下装有openssl,导致  配置时调用配置目录 -I/usr/local/openssl/include，而非系统自带

解决方法

[root@three nrpe-2.13]# vim configure
行6630  去掉 /usr/local/openssl 即可,
如"for dir in $ssl_inc_dir $ssl_dir /usr/local/openssl /usr/local/ssl"
[root@three nrpe-2.13]# ./configure  #再次配置....[root@three nrpe-2.13]# make all
.... *** Compile finished ***                                      #通过

解决方法

在同一网段内virtual_router_id 值不能相同，如果相同会在messages中收到VRRP错误包
所以需要更改 virual_router_id

错误9 fdisk partition table entries are not in disk order

fdisk /dev/sdb  (用你的硬盘位置代替/dev/sdb)

有提示后输入 x 回车，
在命令列表中会有一项
f   fix partition order
输入 f 回车
成功会提示 done.
然后输入 p 回车，查看调整后的分区表
最后输入 w 回车，这个命令是将之前的操作写入硬盘
重启之后就会启用新的分区表。

错误10 ubuntu error:unknown filesystem

因为我的电脑是Ubuntu的，开机用的是grub引导，而grub就放在Ubuntu里的/boot/grub下。由于我修复分区顺序，
导致grub找不到原先的Ubuntu所在分区，自然就找不到/boot/grub了，因此解决这个问题很简单，只要把grub和/boot/grub对应上就可以了。

2 编辑 /boot/grub/grub.cfg

替换原来分区比如, 旧的是 hd0,msdos8 替换成 hd0,mdos6

3 重装grub

grub-install /dev/sda

错误11 /lib/modules/2.6.32-71.el6.x86_64/build: No such file or directory. Stop.

//如果出现如下错误
make: *** /lib/modules/2.6.32-71.el6.x86_64/build: No such file or directory. Stop.

//进去相关的目录看，这个文件是个软链接，显示位红色，说明链接未成功，用一下命令重新链接一次就OK了
ln -s ../../../usr/src/kernels/2.6.32-71.29.1.el6.x86_64/ build

错误12  php

upload_max_filesize = 2M  //上传附件大小限制在2M

vim /etc/php.ini
upload_max_filesize = 16M

 

错误13 maps to localhost, but this does not map back to the address - POSSIBLE BREAK-IN ATTEMPT!

修改  /etc/ssh/ssh_config

vim  /etc/ssh/ssh_config

GSSAPIAuthentication no

 

错误14

nfs:server is not responding,still trying

方法1 ：
我在arm上通过NFS共享文件时出现下面的错误提示
nfs:server is not responding,still trying

原因分析：NFS 的默认传输协议是 UDP，而PC机与嵌入式系统通过UPD交互时就会出现严重的网卡丢包现象。

解决方法：在客户端改用TCP协议，使用下面的命令，
#mount -o tcp 10.10.19.25:/home/export /mnt/local

方法2：
在目标板上通过NFS复制PC机上较大文件到目标板上的时候遇到的问题：
nfs: server *** not responding, still trying

修改方法：
nfs mount时候出现的NFS崩溃，按照以下的方式mount
mount -t nfs -o intr,nolock,rsize=1024,wsize=1024 192.168.1.3/root/somedir /client

 

错误15
