1、OpenSSL源码升级
到https://www.openssl.org/source/ 找想要的版本，拿到链接wget下来：
wget https://www.openssl.org/source/openssl-1.0.1u.tar.gz tar -zxvf openssl-1.0.1u.tar.gz cd openssl-1.0.1u.tar.gz ./config shared zlib //一定记得加上shared选项，不然会导致OpenSSL Library Version 和OpenSSL Header Version不一致 make && make install #备份以前的OpenSSL文件 mv /usr/bin/openssl /usr/bin/openssl.old mv /usr/include/openssl /usr/include/openssl.old #设置软链接 ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl ln -s /usr/local/ssl/include/openssl /usr/include/openssl #更新链接 echo "/usr/local/ssl/lib" >> /etc/ld.so.conf ldconfig -v
如果成功执行
openssl version
会返回刚才安装的版本。
2、重新编译PHP
#查看编译时的参数 /usr/local/php/bin/php -i | grep Command
会返回格式如：
./configure' '--prefix=/usr/local/php' '--with-mysql' '--with-mysqli' '--with-iconv-dir' '--with-zlib' '--with-libxml-dir' '--enable-xml' '--with-curl' '--enable-fpm' '--enable-mbstring' '--with-gd' '--with-openssl' '--with-mhash' '--enable-sockets' '--with-xmlrpc' '--enable-zip' '--enable-soap' '--disable-fileinfo'
把单引号去掉，—with-openssl改成—with-openssl=/usr/local/ssl/，重新编译之前要重装libiconv,
不然会报undefined reference to `libiconv_open。操作如下命令:
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.13.1.tar.gz tar -zxvf libiconv-1.13.1.tar.gz cd libiconv-1.13.1 ./configure --prefix=/usr/local/libiconv make && make install
然后将—with-iconv-dir修改为—with-iconv=/usr/local/libiconv。
然后进入安装的PHP版本的源码包，重新编译，进入PHP相应版本包内，make && make install。
如果是LNMP环境到此就结束了。
3、重新编译Apache
先到安装Apacher的目录下的build/config.nice文件中查看编译安装Apache时的参数，文件内容类似如下：
#! /bin/sh # # Created by configure "./configure" "--prefix=/usr/local/apache" "--enable-mods-shared=most" "--enable-headers" "--enable-mime-magic" "--enable-proxy" "--enable-so" "--enable-rewrite" "--with-ssl" "--enable-ssl" "--enable-deflate" "--enable-suexec" "--with-included-apr" "--with-mpm=prefork" "--with-expat=builtin" "$@"
将双引号、反斜杠去掉，并且在—with-ssl后面换上新OpenSSL的路径，这里安装在/usr/local/ssl/下，就改成—with-ssl=/usr/local/ssl。然后进入Apache对应版本的源码包中重新编译，安装。
成功后phpinfo即可看到新安装的OpenSSL版本。
