CentOS 6.x 最小化安装推荐安装的依赖包
我在日常工作中，新建的xenserver的虚拟机，CentOS release 6.9 (Final)操作系统，采用最小化安装，后续很多操作需要各种依赖包，经过一些时间的积累，推荐安装如下依赖包。前提是需要yum源先配置好，最好能联网，采用网络yum源。
yum clean all
yum -y update
yum -y install gd libxml2-devel libjpeg-devel libpng-devel net-snmp-devel wget telnet vim zip unzip
yum -y install curl-devel libxslt-devel pcre-devel libjpeg libpng libcurl4-openssl-dev
yum -y install libcurl-devel libcurl freetype-config freetype freetype-devel unixODBC libxslt
yum -y install libtool openssl-devel readline-devel readline
yum -y install perl-devel perl-ExtUtils-Embed
yum -y install ncurses-devel.x86_64 openldap-devel.x86_64 lrzsz openssh-clients gcc-g77 bison
yum -y install libmcrypt libmcrypt-devel mhash mhash-devel bzip2 bzip2-devel
yum -y install ntpdate rsync svn patch iptables iptables-services
yum -y install libevent libevent-devel cyrus-sasl cyrus-sasl-devel
yum -y install gd-devel libmemcached-devel memcached git libssl-devel libyaml-devel auto
yum -y install gcc gcc-c++ make autoconf automake ncurses-devel ncurses cmake libaio libaio-devel boost
yum -y install perl-DBI perl-DBD-MySQL perl-Time-HiRes perl-IO-Socket-SSL perl perl-devel
yum -y groupinstall "Server Platform Development" "Development tools"
yum -y groupinstall "Development tools"
另外新建的虚拟机，也需要修改内核参数。
