给PHP开启shmop扩展实现共享内存

在项目开发中，想要实现PHP多个进程之间共享数据的功能，让客户端连接能够共享一个状态，需要开启共享内存函数shmop。如果预期考虑会遇到这方面需求，那么最好在编译PHP的时候添加--with-shmop选项。但是编译的时候没有添加，只能在重新编译配置了。

一、找到php源码包里的扩展目录，进入shmop# cd /usr/local/src/php-7.1.10/ext/shmop/

二、执行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、执行命令开始编译# ./configure --with-php-config=/usr/local/php/bin/php-config

# make && make installSee 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

复制返回的那行路径：/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 //添加此行代码，后面跟上shmop.so

重启php
