Centos7安装swoole扩展操作示例

本文实例讲述了Centos7安装swoole扩展操作,分享给大家供大家参考,具体如下:

我的PHP版本为PHP 7.2.24

更新源

[root@localhost html]# yum update

安装需要支持的扩展

  1. [root@localhost html]# yum install php72w-devel
  2. [root@localhost html]# yum install php72w-pear
  3. [root@localhost html]# yum install gcc
  4. [root@localhost html]# yum install gcc-c++
  5. [root@localhost html]# yum install gcc-g77

安装swoole

  1. [root@localhost html]# pecl install swoole
  2. ...
  3. // 是否启用 PHP Sockets 支持
  4. enable sockets supports? [no] : yes
  5. // 是否启用 OpenSSL 支持
  6. enable openssl support? [no] : yes
  7. // 是否启用 HTTP2 支持
  8. enable http2 support? [no] : yes
  9. // 是否启用 MySQL 原生支持
  10. enable mysqlnd support? [no] : yes

安装成功

  1. Build process completed successfully
  2. Installing '/usr/lib64/php/modules/swoole.so'
  3. Installing '/usr/include/php/ext/swoole/config.h'
  4. install ok: channel://pecl.php.net/swoole-4.4.12
  5. configuration option "php_ini" is not set to php.ini location
  6. You should add "extension=swoole.so" to php.ini

安装失败

PHP Startup: Unable to load dynamic library 'swoole.so' (tried: /usr/lib64/php/modules/swoole.so (/usr/lib64/php/modules/swoole.so: cannot open shared object file: No such file or directory), /usr/lib64/php/modules/swoole.so.so (/usr/lib64/php/modules/swoole.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

// 把extension=swoole.so加到socket的加载后面,在php7.2中进入/etc/php.d下,在sockets.ini中将extension=swoole.so加到extension=sockets.so下面,后重启php-fpm

php -m或者 phpinfo()查看不到swoole

解决方法:

1. 确认安装和配置是否有问题

2、如果使用php -m无法查看swoole,请使用命令service php-fpm restart重启

3、如果使用phpinfo()无法查看swoole,请使用命令service httpd restart重启

  1. C++ preprocessor “/lib/cpp” fails sanity check
  2. // 没有c++库
  3. // yum install glibc-headers
  4. // yum install gcc gcc-c++ gcc-g77
  5. fatal error: openssl/ssl.h: No such file or directory
  6. // 没有openssl/ssl此类文件或目录
  7. // yum install openssl-devel
  8. error “Enable http2 support, require nghttp2 library.
  9. // wget https://github.com/nghttp2/nghttp2/releases/download/v1.34.0/nghttp2-1.34.0.tar.bz2
  10. // tar -xjf nghttp2-1.34.0.tar.bz2
  11. PHP Warning: Module 'swoole' already loaded in Unknown on line 0
  12. // 在修改配置时extension=swoole.so别放在最后,最好放在extension=sockets.so后面

修改配置

  1. [root@localhost html]# vim /etc/php.ini
  2. ...
  3. extension=swoole.so
  4. ....

重启

[root@localhost html]# /bin/systemctl restart php-fpm.service

[root@localhost html]# /bin/systemctl restart httpd.service

验证是否安装成功

php -m 或者 phpinfo() 查看是否有swoole
