注： 本节操作使用PHP7。

安装Redis模块
redis是一个key-value存储系统。和Memcached类似，它支持存储的value类型相对更多，包括string(字符串)、list(链表)、set(集合)和zset(有序集合)。

为PHP加载Redis模块
先查看扩展模块所在目录：
[root@cham002 phpredis-develop]# /usr/local/php7/bin/php -i |grep extension_dir extension_dir => /usr/local/php7/lib/php/extensions/no-debug-zts-20160303 => /usr/local/php7/lib/php/extensions/no-debug-zts-20160303sqlite3.extension_dir => no value => no value
说明： 该目录可以在PHP配置文件php.ini中进行设置（保持默认）
加载Redis模块
编辑PHP的配置文件：
[root@cham002 phpredis-develop]# vim /usr/local/php7/etc/php.ini
说明： 在配置文件中加入“extension=redis.so”即可！该文件中“；”表示注释符号，同“#”。
[root@cham002 phpredis-develop]# /usr/local/php7/bin/php -m |grep redisredis
关于扩展板块
在PHP的源码包中没有第三方模块的包，但是在PHP源码包的/ext/目录下有好多扩展模块，如果所需要的扩展模块在该目录下，可以直接进行安装：
[root@cham002 phpredis-develop]# cd /usr/local/src/php-7.1.6/[root@cham002 php-7.1.6]# lsacinclude.m4 EXTENSIONS Makefile.fragments README.EXT_SKEL run-tests.phpaclocal.m4 footer Makefile.gcov README.GIT-RULES sapiappveyor generated_lists Makefile.global README.input_filter scriptsbuild genfiles Makefile.objects README.MAILINGLIST_RULES server-tests-config.phpbuildconf header makerpm README.md server-tests.phpbuildconf.bat include meta_ccld README.namespaces snapshotCODING_STANDARDS INSTALL missing README.NEW-OUTPUT-API stamp-h.inconfig.guess install-sh mkinstalldirs README.PARAMETER_PARSING_API stub.cconfig.log libphp7.la modules README.REDIST.BINS testsconfig.nice libs netware README.RELEASE_PROCESS travisconfig.status libtool NEWS README.SELF-CONTAINED-EXTENSIONS TSRMconfig.sub LICENSE pear README.STREAMS UPGRADINGconfigure ltmain.sh php7.spec README.SUBMITTING_PATCH UPGRADING.INTERNALSconfigure.in main php7.spec.in README.TESTING vcscleanCONTRIBUTING.md makedist php.gif README.TESTING2 win32CREDITS Makefile php.ini-development README.UNIX-BUILD-SYSTEM Zendext Makefile.frag php.ini-production README.WIN32-BUILD-SYSTEM[root@cham002 php-7.1.6]# ls extbcmath dom gd json odbc pdo_mysql pspell snmp sysvshm xslbz2 enchant gettext ldap opcache pdo_oci readline soap tidy zipcalendar exif gmp libxml openssl pdo_odbc recode sockets tokenizer zlibcom_dotnet ext_skel hash mbstring pcntl pdo_pgsql reflection spl wddxctype ext_skel_win32.php iconv mcrypt pcre pdo_sqlite session sqlite3 xmlcurl fileinfo imap mysqli pdo pgsql shmop standard xmlreaderdate filter interbase mysqlnd pdo_dblib phar simplexml sysvmsg xmlrpcdba ftp intl oci8 pdo_firebird posix skeleton sysvsem xmlwriter
现在扩展模块中没有zip
[root@cham002 php-7.1.6]# /usr/local/php7/bin/php -m |grep zip现在扩展模块中没有zip[root@cham002 php-7.1.6]# cd ext[root@cham002 ext]# cd zip[root@cham002 zip]# /usr/local/php7/bin/phpizeConfiguring for:PHP Api Version: 20160303Zend Module Api No: 20160303Zend Extension Api No: 320160303#执行该命令的目的是生成configure文件，否则无法进行编译安装[root@cham002 zip]# ./configure --with-php-config=/usr/local/php7/bin/php-config[root@cham002 zip]# echo $?0
接下来就make我出现了这种错误。没有没有截图。可以用#make clean
然后在重新执行命令
[root@cham002 zip]# make installInstalling shared extensions: /usr/local/php7/lib/php/extensions/no-debug-zts-20160303/[root@cham002 zip]# ls /usr/local/php7/lib/php/extensions/no-debug-zts-20160303/opcache.so redis.so zip.so
