My environment: lamp environment built by linux centos7.4 php5.6 (php is run as an apache module) Custom compiled and installed, non-yum installation

Install curl:

# 
# 1. 进入php源码目录,执行phpize生成配置文件
# 切换到php源码目录下的 ext/curl/    例我的是: /root/packages/php-5.6.36/ext/curl 执行命令
cd /root/packages/php-5.6.36/ext/curl
/usr/local/php-5.6.36/bin/phpize

# 2. 调用configure生成Makefile文件
./configure --with-php-config=/usr/local/php-5.6.36/bin/php-config

# 3. 编译,并安装
make && make install

# 4. 配置php.ini 开启curl.so
extension= /usr/local/php-5.6.36/lib/php/extensions/no-debug-zts-20131226/curl.so

# 5. 重启服务器
service httpd restart

# 如果是nginx 使用的是php-fpm 重启php-fpm即可 命令: 
# kill -USR2  主进程ID (使用ps -e | grep php-fmp 可查出)

# 6. 查看 php -m
