官网安装
打开 https://zeroc.com/downloads/ice#redhat 选对应的系统，我这里是Centos 7
# 配置 yum
cd /etc/yum.repos.d
sudo wget https://zeroc.com/download/Ice/3.7/el7/zeroc-ice3.7.repo
# Install Ice for C++, Python, PHP, and all Ice services.
sudo yum install ice-all-runtime ice-all-devel
# 查看 php 的模块安装是否成功，成功则有 ice 模块
php -m
源码安装
很不幸这里报错了，so 只有麻烦点自己编译安装
本例错误如下：
PHP Warning: PHP Startup: Unable to load dynamic library 'ice.so' (tried: /usr/lib64/php/modules/ice.so (/usr/lib64/php/modules/ice.so: undefined symbol: zval_used_for_init), /usr/lib64/php/modules/ice.so.so (/usr/lib64/php/modules/ice.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0
