在項目開發中，想要實現PHP多個進程之間共享數據的功能，讓客戶端連接能夠共享一個狀態，需要開啟共享內存函數shmop。如果預期考慮會遇到這方面需求，那么最好在編譯PHP的時候添加--with-shmop選項。但是編譯的時候沒有添加，只能在重新編譯配置了。
一、找到php源碼包里的擴展目錄，進入shmop
# cd /usr/local/src/php-7.1.10/ext/shmop/
二、執行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、執行命令開始編譯
# ./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開啟擴展
復制返回的那行路徑：/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 //添加此行代碼，后面跟上shmop.so
重啟php
