--此篇博文记录自己学习Linux及Linux工作中遇到的各种故障及问题的汇总


一、CentOS6.5中安装Mysql后在建立mysql库时并初始化时出现错误提示:

Installing MySQL system tables...

./bin/mysqld: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

经网上查询,用yum安装compat-libstdc++-33.x86_64包后重新初始化即可解决。



二、CentOS6.5中安装PHP,在编译时出现错误提示:

checking for xml2-config path...

configure: error: xml2-config not found. Please check your libxml2 installation.


解决方案:

经分析是由于缺少libxml2-devel.i686组件导致,用yum安装libxml2-devel.i686包后重新编译即可。



三、CentOS6.5中安装PHP,在编译时出现错误提示:

checking whether libxml build works... no

configure: error: build test failed.  Please check the config.log for details.

yum erase zlib-devel

yum install -y zlib-devel

yum install -y libxml2-devel

解决方案:

yum install -y bzip2-devel



六、CentOS6.5中安装PHP,在编译时出现错误提示:

configure: error: mcrypt.h not found. Please reinstall libmcrypt.

八、CentOS6.5中用scp命令从其他系统中拷贝文件时出现错误提示:ssh: connect to host 188.188.7.41 port 22: Connection refused


解决方案:

安装完openssh-clents及openssh-server后用检查iptables中SSH端口是什么,用scp -P SSH端口号 [email protected]:/tmp/1.txt ./2.txt  ---指定SSH端口号为2222并将远程192.168.0.22的root帐户服务器的/tmp/1.txt文件拷贝到本机当前目录的2.txt



九、CentOS6.5中安装LNMP的PHP时出现错误提示:

Trying other mirror.

Error: Cannot retrieve repository metadata (repomd.xml) for repository: addons. Please verify its path and try again


解决方案:

添加sohu源

vim CentOS-Media.repo

把enabled=1改成enabled=0

然后再修改:你所有采用的源,例如我采用的是sohu 的,就修改sohu的:

vim CentOS-Base-sohu.repo

在[addons] 下面添加:

enabled=0

然后,再执行yum makecache



十七、CentOS6.5中使用yum工具安装ipvsadm提示错误:GPG key retrieval failed: [Errno 14] Could not open/read file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5

编辑tomcat安装目录下的bin/catalina.sh文件在cygwin=false一行前加入JAVA_OPTS="-server -Xms800m -Xmx800m -XX:PermSize=256m -XX:MaxPermSize=512m -XX:MaxNewSize=512m"(内存大小可自行设定)


二十二、CentOS6.5中安装vsftpd服务后登陆测试提示530 Login incorrect


解决方案:

vim /etc/pam.d/vsftpd将文件中的/lib内容修改为/lib64,重启vsftpd服务即可


二十三、CentOS6.5中对免编译二进制mysql包进行初始化时提示:bad ELF interpreter: No such file or directory
