Swoole学习之Swoole源码安装(二)

一、swoole源码下载

Swoole官网下载:https://www.swoole.com/，我们用源代码(开源中国) 库下载：

这里用git直接将源代码包克隆到本地

root@5ee6bfcc1310:/work/study/softpackage# git clone git@gitee.com:swoole/swoole.git

或者直接用curl直接下载,然后解压缩包：

curl https://gitee.com/swoole/swoole/repository/archive/master.zip

二、swoole源码安装

swoole和php的源码安装基本一样，但是 swoole 没有 configure 安装文件，这就需要我们使用PHP自带的工具 phpize(phpize用来添加扩展模块的,可以建立PHP的外挂模块) 来生成这样的文件。

进入 swoole源码包目录下，然后执行/work/study/soft/php/bin/phpize 命令：

swoole# /work/study/soft/php/bin/phpize
Configuring for:
PHP Api Version:         20170718
Zend Module Api No:      20170718
Zend Extension Api No:   320170718

这时我们查看swoole源码包，会生成多个文件，其中就有 configure 文件。

编译：

swoole#  ./configure --with-php-config=/work/study/soft/php/bin/php-config
swoole# make && make install

--with 表示指定安装的php版本，如果系统中有多个php版本的话，需要指定

编译结果：

...

PATH="$PATH:/sbin" ldconfig -n /work/study/softpackage/swoole/modules
----------------------------------------------------------------------
Libraries have been installed in:
   /work/study/softpackage/swoole/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'.

Installing shared extensions:     /work/study/soft/php/lib/php/extensions/no-debug-non-zts-20170718/
Installing header files:          /work/study/soft/php/include/php/
root@5ee6bfcc1310:/work/study/softpackage/swoole#

扩展放在了 /work/study/soft/php/lib/php/extensions/no-debug-non-zts-20170718/ 目录下了，我们查看该目录：

root@5ee6bfcc1310:/work/study/soft/php/bin# cd /work/study/soft/php/lib/php/extensions/no-debug-non-zts-20170718/
root@5ee6bfcc1310:/work/study/soft/php/lib/php/extensions/no-debug-non-zts-20170718# ls -l
total 21820
-rwxr-xr-x 1 root root  5227454 Aug 27 18:07 opcache.a
-rwxr-xr-x 1 root root  2413144 Aug 27 18:07 opcache.so
-rwxr-xr-x 1 root root 14696248 Aug 28 11:06 swoole.so

swoole.so 这个文件就是我们编译后的扩展文件。

三、PHP支持Swoole

php如果要使用扩展类库，必须在 php.ini 文件中做一些配置才能使用，否则会报错找不到该类文件。

编辑php.ini文件

root@5ee6bfcc1310:/work/study/soft/php/lib# vim php.ini

extension 扩展新增一行：

extension=swoole

检查一下，是否有swoole扩展：

root@5ee6bfcc1310:/work/study/soft/php/lib# php -m
[PHP Modules]
Core
ctype
date
dom
fileinfo
filter
hash
iconv
json
libxml
pcre
PDO
pdo_sqlite
Phar
posix
Reflection
session
SimpleXML
SPL
sqlite3
standard
swoole
tokenizer
xml
xmlreader
xmlwriter

[Zend Modules]

我们可以看到PHP的扩展已经有 swoole，至此，我们的PHP和Swoole安装编译完成 ^_^。
