给 PHP 开启 shmop 扩展实现同享内存

在项目开发中，想要实现PHP多个进程之间同享数据的功效，让客户端连接能够同享一个状态，需要开启同享内存函数shmop。假如预测思考会碰到这方面需求，那么最好在编译PHP的时候增加--with-shmop选项。但是编译的时候没有增加，只能在从新编译配置了。

一、寻到php源码包里的扩展名目，进入shmop

# cd /usr/local/src/php-7.1.10/ext/shmop/

二、施行phpize，生成配置

# phpize
[root@bogon shmop]# ls
acinclude.m4    build         config.h.in  config.nice    configure     CREDITS     libtool    Makefile.fragments  missing        package2.xml  README         shmop.la
aclocal.m4      config.guess  config.log   config.status  configure.in  include     ltmain.sh  Makefile.global     mkinstalldirs  package.xml   run-tests.php  shmop.lo
autom4te.cache  config.h      config.m4    config.sub     config.w32    install-sh  Makefile   Makefile.objects    modules        php_shmop.h   shmop.c        tests

三、施行命令开端编译

# ./configure --with-php-config=/usr/local/php/bin/php-config
# make && make install
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
Build complete.
Don't forget to run 'make test'.
Installing shared extensions:     /usr/local/php/lib/php/extensions/no-debug-non-zts-20160303/

四、修改php.ini开启扩展

复制返回的那行途径：/usr/local/php/lib/php/extensions/no-debug-non-zts-20160303/

# vim /usr/local/php/etc/php.ini
;extension=php_pdo_sqlite.dll
;extension=php_pgsql.dll
extension=/usr/local/php/lib/php/extensions/no-debug-non-zts-20160303/shmop.so   //增加此行代码，后面跟上shmop.so

重新启动php
