解决办法：升级 curl 版本
具体操作步骤：
1）安装 curl
# rpm -Uvh http://www.city-fan.org/ftp/contrib/yum-repo/rhel6/x86_64/city-fan.org-release-2-1.rhel6.noarch.rpm # yum --showduplicates list curl --disablerepo="*" --enablerepo="city*" #搜索curl查看是否有高版本的 # vim /etc/yum.repos.d/city-fan.org.repo 修改该repo的enable为1 [city-fan.org] name=city-fan.org repository for Red Hat Enterprise Linux (and clones) $releasever ($basearch) #baseurl=http://mirror.city-fan.org/ftp/contrib/yum-repo/rhel$releasever/$basearch mirrorlist=http://mirror.city-fan.org/ftp/contrib/yum-repo/mirrorlist-rhel$releasever enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-city-fan.org # yum install curl
2）重新编译zabbix
# ./configure --prefix=/usr/local/zabbix --enable-server --enable-agent --enable-proxy --with-mysql=/usr/local/mysql/bin/mysql_config --enable-ipv6 --with-net-snmp --with-libcurl --with-libxml2 # make install # /etc/init.d/zabbix_server stop # /etc/init.d/zabbix_server start
