centos7 升级curl-8.2.1 支持http2 （yum update）

转载于：https://www.cnblogs.com/huangweimin/articles/15882913.html

CentOS 7 默认的 curl 版本最新就到 7.29 ，7.29是不支持http2的

?

1 2 3 4 5 6 7 8

# curl  --version curl 7.29.0 (x86_64-redhat-linux-gnu) libcurl/7.29.0 NSS/3.53.1 zlib/1.2.7 libidn/1.28 libssh2/1.8.0 Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp scp sftp smtp smtps telnet tftp Features: AsynchDNS GSS-Negotiate IDN IPv6 Largefile NTLM NTLM_WB SSL libz unix-sockets     # curl  --http2 https://www.baidu.com curl: option --http2: is unknown curl: try 'curl --help' or 'curl --manual' for more information

　　

最近业务上有需求，需要curl支持http2，其实是php依赖的libcurl扩展，本质上是libcurl的版本低了。所以需要升级curl，但是网上的文章都是说要编译curl安装，比较麻烦，容易出错。且还要区分安装openSSL还是NSS， 所以建议使用rpm的yum update来更新curl

 

一、添加city-fan.org的源

vim /etc/yum.repos.d/city-fan.org.repo  # 编辑文件添加如下

[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=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-city-fan.org

[city-fan.org-debuginfo]
name=city-fan.org debuginfo repository for Red Hat Enterprise Linux (and clones) $releasever ($basearch)
#baseurl=http://www.city-fan.org/ftp/contrib-debug/rhel$releasever/$basearch
mirrorlist=http://www.city-fan.org/ftp/contrib-debug/mirrorlist-rhel$releasever
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-city-fan.org

[city-fan.org-source]
name=city-fan.org source repository for Red Hat Enterprise Linux (and clones) $releasever
#baseurl=http://mirror.city-fan.org/ftp/contrib/yum-repo/rhel$releasever/source
mirrorlist=http://mirror.city-fan.org/ftp/contrib/yum-repo/source-mirrorlist-rhel$releasever
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-city-fan.org

 

二、更新curl

# yum update curl

 

三、测试，发现curl已经更新了，支持http2
