升级ntpd到4.2.8p17，ntp编译报recompile with -fPIC错误解决

背景

低版本的ntp会有漏洞，需要升级到最新版本4.2.8p17

检查ntpd版本

/usr/sbin/ntpd --version

下载部署包

https://archive.ntp.org/ntp4/ntp-4.2/ntp-4.2.8p17.tar.gz

安装依赖包

每个文档的都不一样，这里索性都安装

yum install gcc gcc-c++ openssl-devel libstdc++* libcap* m4 autoconf libtool gcc gcc-c++ ncurses-devel cmake make gcc libcap libcap-devel glic-devel automake libevent*

备份原有配置文件

scp -r /etc/ntp /etc/ntp.bak
scp -r /etc/ntp.conf /etc/ntp.conf.bak
scp -r /etc/init.d/ntpd /etc/init.d/ntpd.bak
scp -r /etc/sysconfig/ntpd /etc/sysconfig/ntpd.bak
scp -r /etc/sysconfig/ntpdate /etc/sysconfig/ntpdate.bak
scp -r /usr/sbin/ntpd /usr/sbin/ntpd.bak

移除ntp

yum remove ntp ntpdate -y

解压安装包

tar -zxvf ntp-4.2.8p17.tar.gz

cd ntp-4.2.8p17/
install -v -m710 -o ntp -g ntp -d /var/lib/ntp

./configure --prefix=/usr --bindir=/usr/sbin --enable-all-clocks --enable-parse-clocks --docdir=/usr/share/doc/ntp-4.2.8p17 --enable-all-clocks --enable-parse-clocks --enable-clockctl CFLAGS="-fPIC"


make && make install

#注意此处CFLAGS=“-fPIC”，p15不需要这个参数，但是p17要有
否则会报下面错误
