安装OpenSSL的最新版
话不多说，直接上安装步骤
#cd /usr/local/src # 跳过证书获取失败 # wget https://www.openssl.org/source/openssl-1.0.2n.tar.gz --no-check-certificate # tar xzvf openssl-1.0.2n.tar.gz # cd openssl-1.0.2n # ./config shared enable-ssl2 enable-ssl3 --prefix=/usr # make depend # make # #确认没有错误 # make test # make install # #如果顺利的话就好了 # openssl version
进展顺利
安装curl的最新版
这里也大体上就那样,不过，因为wget curl的文件的时候，SSL通信用其他的方法取得
# cd /usr/local/src # #如果wget不能用其他的方法下载 # wget https://curl.haxx.se/download/curl-7.58.0.tar.gz # tar xzvf curl-7.58.0.tar.gz # cd curl-7.58.0 # ./configure --enable-libcurl-option --with-ssl=/usr --prefix=/usr
./confirure 的输出结果的一部分如下：
--如果弄错with-ssl的目录指定，SSL support的部分变成no。
--libcurl option:也确认一下是enabled吧。
configure: Configured to build curl/libcurl: curl version: 7.58.0 Host setup: x86_64-pc-linux-gnu Install prefix: /usr Compiler: gcc SSL support: enabled (OpenSSL) SSH support: no (--with-libssh2) zlib support: enabled brotli support: no (--with-brotli) GSS-API support: no (--with-gssapi) TLS-SRP support: enabled resolver: POSIX threaded IPv6 support: enabled Unix sockets support: enabled IDN support: no (--with-{libidn2,winidn}) Build libcurl: Shared=yes, Static=yes Built-in manual: enabled --libcurl option: enabled (--disable-libcurl-option) Verbose errors: enabled (--disable-verbose) SSPI support: no (--enable-sspi) ca cert bundle: /etc/pki/tls/certs/ca-bundle.crt ca cert path: no ca fallback: no LDAP support: enabled (OpenLDAP) LDAPS support: enabled RTSP support: enabled RTMP support: no (--with-librtmp) metalink support: no (--with-libmetalink) PSL support: no (libpsl not found) HTTP2 support: disabled (--with-nghttp2) Protocols: DICT FILE FTP FTPS GOPHER HTTP HTTPS IMAP IMAPS LDAP LDAPS POP3 POP3S RTSP SMB SMBS SMTP SMTPS TELNET TFTP
然后 make
# make
中途输出Warning: compression requested but Gzip is not available，这次没有通过！好像在hugehelp.c上输出了什么，应该不是严重的错误……？
然后 make install
# make install
下面显示输出结果的一部分。
/bin/sh ../libtool --mode=install /usr/bin/install -c libcurl.la '/usr/lib' libtool: install: /usr/bin/install -c .libs/libcurl.so.4.5.0 /usr/lib/libcurl.so.4.5.0 (略) ---------------------------------------------------------------------- Libraries have been installed in: /usr/lib If you ever happen to want to link against installed libraries in a given directory, LIBDIR, you must either use libtool, and specify the full pathname of the library, or use the '-LLIBDIR' flag during linking and do at least one of the following: - add LIBDIR to the 'LD_LIBRARY_PATH' environment variable during execution - add LIBDIR to the 'LD_RUN_PATH' environment variable during linking - use the '-Wl,-rpath -Wl,LIBDIR' linker flag - have your system administrator add LIBDIR to '/etc/ld.so.conf' See any operating system documentation about shared libraries for more information, such as the ld(1) and ld.so(8) manual pages. ----------------------------------------------------------------------
安装好了， curl -V 不过有错误。
curl: error while loading shared libraries: libcurl.so.4: cannot open shared object file: No such file or directory
好像无法读取库。
如果用ldd /usr/bin/curl确认的话，确实没有libcurl.so.4 =>的参照处。但是make install的时候/usr/lib/libcurl.so.4.5.0上写着安装了。
用共享库就好。（http://www.8wave.net/ldconfig.html）
# # 在末尾添加“/usr/lib” # vim /etc/ld.so.conf.d/lib.conf # ldconfig
这样就OK了。
curl -V
输出结果
curl 7.58.0 (x86_64-pc-linux-gnu) libcurl/7.58.0 OpenSSL/1.0.2n zlib/1.2.3 Release-Date: 2018-01-24 Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp smb smbs smtp smtps telnet tftp Features: AsynchDNS IPv6 Largefile NTLM NTLM_WB SSL libz TLS-SRP UnixSockets HTTPS-proxy
大功告成！
