有时候安装yum包，发现有的已经安装过了但是如果执行安装，yum需要检查源，输出一堆的信息，看起来很烦，于是就想到了先检查后安装，如果本地已经安装，不执行安装，如果没有安装就进行安装。
去重后需要安装的yum安装包如下：
autoconf bison bison-devel bzip2 bzip2-devel ca-certificates cairo-devel c-ares c-ares-devel cmake crontabs curl curl-devel diffutils
e2fsprogs e2fsprogs-devel expat-devel file flex freetype freetype-devel gcc gcc-c++ gcc-g77 gd gd-devel gettext gettext-devel git-core glib2 gl
ib2-devel glibc.i686 gmp-devel icu kernel-devel krb5 krb5-devel libaio-devel libcap libc-client-devel libcurl libcurl-devel libevent libevent-d
evel libicu-devel libidn libidn-devel libjpeg libjpeg-devel libpng libpng10 libpng10-devel libpng-devel libstdc++.so.6 libtool libtool-libs lib
webp libwebp-devel libxml2 libxml2-dev libxml2-devel libXpm-devel libxslt libxslt* libxslt-devel lsof make ncurses ncurses-devel net-tools open

shell源码
cat yumci.sh
#!/bin/bash
#writen by Aiker
myum() {
if ! rpm -qa|grep -q "^$1"
then
yum install -y $1
check_ok
else
echo $1 already installed.
fi
}
check_ok() {
if [ $? != 0 ]
then
echo "Error,Check the error log."
fi
}
