Note that php5.6 needs to install openssl 1.1 or lower version.
wget https://www.openssl.org/source/old/1.0.0/openssl-1.0.0.tar.gz
tar xzvf openssl-1.0.0.tar.gz
cd openssl-1.0.0
# 编译支持的系统查看
uname -a
./Configure LIST | grep darwin
# 默认会生成shared库（动态），如果加上no-shared，就不会生成动态库
./Configure darwin64-x86_64-cc --prefix=/usr/local/opt/openssl no-asm --openssldir=/usr/local/ssl
# 生成MakeFile
./config
./Configure darwin64-x86_64-cc
# 重新配置Makefile
./Configure darwin64-x86_64-cc --prefix=/usr/local/opt/openssl no-asm --openssldir=/usr/local/ssl
make && make install
