目前centos6的最新curl版本为7.19.1
但是例如微信付款等需要双向证书的curl版本要求7.20.1以上
1、安装repo
rpm -Uvh http://www.city-fan.org/ftp/contrib/yum-repo/rhel6/x86_64/city-fan.org-release-2-1.rhel6.noarch.rpm
2、查看该 repo 包含的 curl 版本
yum --showduplicates list curl --disablerepo="*" --enablerepo="city*"
3、修改该repo的enable为1
vi /etc/yum.repos.d/city-fan.org.repo
如下所示
[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
4、安装最新的curl
yum install curl
5、如果提示缺少依赖 libnghttp2.so.14()(64bit)
rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/Packages/l/libnghttp2-1.6.0-1.el6.1.x86_64.rpm
然后重复第4步即可
6、查看curl版本
curl -V
