有时候安装一些东西总是会遇到一些问题，问题不大，记录下来，也算是实践心得吧。

git clone https://github.com/mongodb/mongo-php-driver.git 
cd 目录
phpize

发现出现报错Configuring for:PHP Api Version: 20121113Zend Module Api No: 20121212Zend Extension Api No: 220121212/usr/bin/m4:config.m4:364: cannot open `src/libmongoc/build/autotools/m4/ax_prototype.m4‘: No such file or directory/usr/bin/m4:config.m4:365: cannot open `src/libmongoc/build/autotools/CheckCompiler.m4‘: No such file or directory/usr/bin/m4:config.m4:366: cannot open `src/libmongoc/build/autotools/WeakSymbols.m4‘: No such file or directory/usr/bin/m4:config.m4:367: cannot open `src/libmongoc/build/autotools/m4/ax_pthread.m4‘: No such file or directory/usr/bin/m4:config.m4:399: cannot open `src/libbson/build/autotools/CheckAtomics.m4‘: No such file or directory/usr/bin/m4:config.m4:400: cannot open `src/libbson/build/autotools/FindDependencies.m4‘: No such file or directory/usr/bin/m4:config.m4:401: cannot open `src/libbson/build/autotools/m4/ac_compile_check_sizeof.m4‘: No such file or directory/usr/bin/m4:config.m4:402: cannot open `src/libbson/build/autotools/m4/ac_create_stdint_h.m4‘: No such file or directory/usr/bin/m4:config.m4:444: cannot open `src/libmongoc/build/autotools/Versions.m4‘: No such file or directory/usr/bin/m4:config.m4:458: cannot open `src/libbson/build/autotools/Versions.m4‘: No such file or directoryautom4te: /usr/bin/m4 failed with exit status: 1

应该是是这样才对。Configuring for:PHP Api Version: 20121113Zend Module Api No: 20121212Zend Extension Api No: 220121212

经过查询，发现缺少东西，安装。

git submodule sync && git submodule update --init

重新安装扩展：

phpize --clean
phpize

yum install cyrus-sasl-devel

$ ./configure
$ make install

修改php.ini添加

extension=mongo.so

php mongodb driver
