1. 在php7.4中安装swoole，但找不到这个扩展安装

2. 服务器下载源码解压安装

http://pecl.php.net/package/swoole

下载4.8.0版本

解压到/www/server/php/74/下

3. 发现报错问题；

更新一下依赖

yum update
yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5-devel libidn libidn-devel openssl openssl-devel nss_ldap openldap openldap-devel openldap-clients openldap-servers libxslt-devel libevent-devel ntp libtool-ltdl bison libtool vim-enhanced

 

4. 删除缓存

make clean
make distclean
sudo rm -rf modules/

5. 输入命令

# 编译安装
/www/server/php/74/bin/phpize
./configure --with-php-config=/www/server/php/74/bin/php-config --enable-openssl
make
sudo make install

 开始编译

耐心等待

 成功

修改配置文件

6.配置 PHP

extension=swoole.so
