----------------------------------------------------------------------

Libraries have been installed in:

/home/shenbian/php-5.3.3/ext/pcntl/modules

If you ever happen to want to link against installed libraries

in a given directory, LIBDIR, you must either use libtool, and

specify the full pathname of the library, or use the `-LLIBDIR'

flag during linking and do at least one of the following:

- add LIBDIR to the `LD_LIBRARY_PATH' environment variable

during execution

- add LIBDIR to the `LD_RUN_PATH' environment variable

during linking

- use the `-Wl,--rpath -Wl,LIBDIR' linker flag

- have your system administrator add LIBDIR to `/etc/ld.so.conf'

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'.

在php.ini中添加pcntl.so

重启php-fpm：

PHP Warning: PHP Startup: Invalid library (maybe not a PHP library) 'pcntl.so' in Unknown on line 0

Warning: PHP Startup: Invalid library (maybe not a PHP library) 'pcntl.so' in Unknown on line 0

原因是：

我在编译的php的时候已经指定了enable-pcntl,就不需要再php.ini中加extension=pcntl.so

还有 多进程只能在命令行模式下使用
