gcc元件下載地址：http://pan.baidu.com/s/10ZdD0
bash補丁包下載地址：http://ftp.gnu.org/gnu/bash/bash-4.4.18.tar.gz

1、複製到linux系統/root目錄下並解壓gcc-4.4.7-4.el6.x86_64.rar，然後分別進行安裝
[[email protected] home]#rpm -ivh mpfr-2.4.1-6.el6.x86_64.rpm
[[email protected] home]#rpm -ivh ppl-0.10.2-11.el6.x86_64.rpm
[[email protected] home]#rpm -ivh cpp-4.4.7-4.el6.x86_64.rpm
[

[email protected] home]#rpm -ivh cloog-ppl-0.15.7-1.2.el6.x86_64.rpm
[[email protected] home]#rpm -ivh gcc-4.4.7-4.el6.x86_64.rpm
2、上傳bash-4.4.18.tar.gz到伺服器並解壓縮；
進入壓縮後的目錄
[[email protected] home]# cd bash-4.4.18
確保安裝了gcc元件後，進行編譯安裝即可
[[email protected] bash-4.4.18]# ./configure && make && make install
安裝完畢需要做軟連結，否則遠端登陸檢視系統bash版本時仍舊是老版本
[

[email protected] bash-4.4.18]# mv /bin/bash /bin/bash.bak //將原檔案改名備份
[[email protected] bash-4.4.18]# ln -s /usr/local/bin/bash /bin/bash //做軟連結
[[email protected] bash-4.4.18]# bash -version //檢視bash版本
