安装软件常见问题汇总（不断更新）
1. 修改安装路径，避开root
1.1 configure
./configure --prefix=./
2. 报错说时间不对的
make clean
3. 缺少perl模块
待定
4. 解决非root用户yum安装问题
比如想安装graphviz，可以这样查看
yum list 'graphviz*'
下载rpm包
然后我们从仓库中下载rpm包，比如我们要下载graphviz.x86_64，我们可以这样下载：
yumdownloader graphviz.x86_64
解压RPM包
rpm2cpio graphviz-2.30.1-19.el7.x86_64.rpm |cpio -idvm
添加环境变量
如果解压的路径是在home目录的话，那么需要这样添加即可
vim ~/.bashrc
export PATH=$PATH:$HOME/usr/bin/
5. 找不到glib文件，比如：/lib64/libc.so.6: version `GLIBC_2.14' not found
先查看现有情况
ll /lib64/libc.so.6
发现有一个了，只是版本不同，比如我现在有的是libc-2.12.so
先去下载一个想要的版本：http://ftp.gnu.org/gnu/glibc/
wget http://ftp.gnu.org/gnu/glibc/glibc-2.14.tar.gz
wget http://ftp.gnu.org/gnu/glibc/glibc-ports-2.14.tar.gz
tar -xvf glibc-2.14.tar.gz
tar -xvf glibc-ports-2.14.tar.gz
mv glibc-ports-2.14 glibc-2.14/ports
mkdir glibc-build-2.14
cd glibc-build-2.14
../glibc-2.14/configure --prefix=/path/to/this/directory/prefix
#这里报了一个神奇的错误，说环境变量不能包括这个文件夹，解决办法：https://www.cnblogs.com/emanlee/p/7153212.html
make
make install
ll libc.so.6
会出现这个libc.so.6 -> libc.so
strings libc.so | grep GLIBC
看到一长串文件
修改软连接（往下我没办法进行，没有root权限；更换root权限后可操作）
cp libc.so /lib64/libc-2.14.so #这里为了保持原有libc.so的内容
rm -f /lib64/libc.so.6
LD_PRELOAD=/lib64/libc-2.14.so ln -s /lib64/libc-2.14.so /lib64/libc.so.6
以上完成后，用户一登录报错如下：
-bash: warning: setlocale: LC_CTYPE: cannot change locale (en_US.UTF-8): No such file or directory
-bash: warning: setlocale: LC_COLLATE: cannot change locale (en_US.UTF-8): No such file or directory
-bash: warning: setlocale: LC_MESSAGES: cannot change locale (en_US.UTF-8): No such file or directory
-bash: warning: setlocale: LC_NUMERIC: cannot change locale (en_US.UTF-8): No such file or directory
-bash: warning: setlocale: LC_TIME: cannot change locale (en_US.UTF-8): No such file or directory
用locale命令查看，
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
继续解决这个问题：
root下
vi /etc/sysconfig/i18n
添加两句话
LC_ALL=C
export LC_ALL
保存后source /etc/sysconfig/i18n
解决

今天用miniconda3的时候又是上述语言报错出现了，查了一堆解决办法
一说，每次运行前都要先运行两行
export LC_ALL=en_US.utf-8
export LANG=en_US.utf-8
试了试，又报错
$export LC_ALL=en_US.utf-8
-bash: warning: setlocale: LC_ALL: cannot change locale (en_US.utf-8): No such file or directory
-bash: warning: setlocale: LC_ALL: cannot change locale (en_US.utf-8)
$export LANG=en_US.utf-8
有人说，重新安装一个rpm即可
rpm -ivh glibc-common-2.5-42.i386.rpm
我没找到这个安装文件
glib下载ftp地址：ftp://ftp.gnu.org/gnu/glibc/
于是，找到了如下解决办法：
针对ubuntu来说
sudo locale-gen en_US.UTF-8
或
sudo locale-gen
重新编译该字符编码（我不是ubuntu，没有尝试是否可行）
针对cenOS来说，没有locale-gen命令，于是借助了这个帖子：
yum reinstall glibc-common
又遇到新的问题
Loaded plugins: aliases, changelog, fastestmirror, kabi, presto, refresh-packagekit, security, tmprepo, verify, versionlock
Loading support for CentOS kernel ABI
Setting up Reinstall Process
Determining fastest mirrors
YumRepo Error: All mirror URLs are not using ftp, http[s] or file.
Eg. Invalid release/repo/arch combination/
removing mirrorlist with no valid mirrors: /var/cache/yum/x86_64/6/base/mirrorlist.txt
Error: Cannot find a valid baseurl for repo: base
又继续找解决办法
1. Go to /etc/yum.repos.d/ directory:
cd /etc/yum.repos.d/
2. Make copy of original file:
cp CentOS-Base.repo CentOS-Base.repo.old
3. Open and edit file with any text editor:
vi CentOS-Base.repo
4. Replace mirrorlist‘s
Replace sections:
[base]
[updates]
[extras]
With following:
[base]
name=CentOS-$releasever - Base
# mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra
# baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
baseurl=https://vault.centos.org/6.10/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
# released updates
[updates]
name=CentOS-$releasever - Updates
# mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates&infra=$infra
# baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/
baseurl=https://vault.centos.org/6.10/updates/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
# additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras
# mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras&infra=$infra
# baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/
baseurl=https://vault.centos.org/6.10/extras/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
5. Clean yum cache
yum clean all
6. Run again yum update command:
yum update
到这为止，还是没有修改过来。。。。
又过了几天，有一天修好了服务器的网络问题
再次试一试yum
yum install glibc-common
