问题描述

Linux 系统（Ubuntu/Debian/RHEL/CentOS）编译 PHP 5 版本，启用 openssl扩展。

$ ./configure --prefix=/opt/php-5.6.40 --with-openssl
$ make

最后出现 一下错误。

解决方法

PHP 5 不能使用最新版的 openssl 编译，可以降低 openssl 的版本。

$ curl -O https://www.openssl.org/source/old/1.0.2/openssl-1.0.2u.tar.gz
$ tar xf openssl-1.0.2u.tar.gz
$ cd openssl-1.0.2u
$ ./config --prefix=/opt/openssl-1.0.2u
$ make
$ sudo make install

修改 -with-openssl 的路径，重新编译 PHP。

$ ./configure --prefix=/opt/php-5.6.40 --with-openssl=/opt/openssl-1.0.2u
$ make
$ make install
