我一直尝试安装一些 PECL，但它们都返回相同类型的错误。与时区有关吗？我正在运行 RedHat x86_64 es5。
尝试安装 geoip-1.0.7：
root@server [~]# pecl install geoip-1.0.7
downloading geoip-1.0.7.tgz ...

Warning: strtotime(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/Chicago' for 'CST/-6.0/no DST' instead in PEAR/Validate.php on line 489

发生了什么事？有谁能帮忙...
答案1
根据我的经验，“pecl install packagename”很少起作用。
我只需下载最新的 pecl tarball、解压缩、phpize（确保编译/安装后 php 在你的路径中）、./configure、make、make install、service php-fpm restart
例如，使用 geo-ip pecl 包，尝试
获得http://pecl.php.net/get/geoip-1.0.8.tgz
cd geoip-1.0.8
phpize
./configure
make
make install
echo "extenstion=geoip.so" >> /path/to/php.ini
sudo service php-fpm|apache restart
编辑：
如果你缺少一个开发包，编译错误会告诉你，然后你
yum 安装 missingpkg-dev
编辑：
您的软件包似乎无法安装的具体原因是它是为不同的系统构建的。一般来说，如果您从源代码进行编译，您会更高兴，因为您知道发生了什么。

尝试：
mount -o remount,exec,suid /tmp
mount -o remount,exec,suid /var/tmp
答案3
时区警告（您应该通过在 php.ini 中设置时区来更正）与实际问题完全无关，实际问题是“错误：无法运行 C 编译程序”行。您可能没有gcc和/或没有make从包管理器安装。yum groupinstall "Development Tools"或者yum install gcc make可能会奏效。
