Centos7.6之glibc2.17版本升级至2.31

# 升级步骤
## 2.1、安装要求
```
wget https://mirrors.aliyun.com/gnu/glibc/glibc-2.31.tar.gz
tar -zxvf glibc-2.31.tar.gz
cd glibc-2.31/
cat INSTALL | grep -E  "newer|later"
		   * GNU 'make' 4.0 or newer
		   * GCC 6.2 or newer
			 building the GNU C Library, as newer compilers usually produce
		   * GNU 'binutils' 2.25 or later
		   * GNU 'texinfo' 4.7 or later
		   * GNU 'bison' 2.7 or later
		   * GNU 'sed' 3.02 or newer
		   * Python 3.4 or later
		   * GDB 7.8 or later with support for Python 2.7/3.4 or later
		   * GNU 'gettext' 0.10.36 or later

```
根据glibc安装要求，需要达到上述条件，才可进行glibc2.31版本编译安装。
## 2.2、安装基础库
```
yum install -y texinfo
yum install -y mlocate
yum install -y bzip2
yum install -y bison
yum groupinstall -y "Development Tools"

```
说明：如果系统环境未安装gcc环境，请执行如下命令：
```
yum install gcc gcc-c++ -y
```
## 2.3、编译安装gcc
```
wget https://mirrors.aliyun.com/gnu/gcc/gcc-9.3.0/gcc-9.3.0.tar.gz
tar axf gcc-9.3.0.tar.gz
cd gcc-9.3.0
./contrib/download_prerequisites
cat /proc/cpuinfo| grep "processor"| wc -l
mkdir build
cd build
../configure --enable-checking=release --enable-language=c,c++ --disable-multilib --prefix=/usr
make -j6
make install
gcc -v
```
## 2.4、编译安装make
```
wget https://mirrors.aliyun.com/gnu/make/make-4.3.tar.gz
tar axf make-4.3.tar.gz
cd make-4.3
mkdir build
cd build
../configure --prefix=/usr && make && make install
make -v

```
## 2.5、安装python3
```
wget https://mirrors.aliyun.com/gnu/glibc/glibc-2.31.tar.gz
cd glibc-2.31/
mkdir build
cd build
../configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin --disable-sanity-checks --disable-werror
make -j6
make install
make localedata/install-locales
ldd --version
ll /lib64/libc.so.6

```
安装完成后检查glibc版本

如果执行yum命令卡住，可进行如下操作：
```
# 删除rpm数据文件
rm -f /var/lib/rpm/__db.00*
# 重建rpm数据文件
rpm --rebuilddb

```
