在 CentOS 7.5 64 位、PHP 7.4 中报错：PHP Core Warning ‘yii\base\ErrorException’ with message ‘Module ‘zip’ already loaded’ 的分析解决

1、在 CentOS 7.5 64 位、PHP 7.4 中报错：PHP Core Warning ‘yii\base\ErrorException’ with message ‘Module ‘zip’ already loaded’，如图1

2、查看 phpinfo() 的信息，确认 zip 扩展已经安装。如图2

3、检查 /usr/local/php/etc/php.ini 中是否存在 zip。存在。

;extension = "memcached.so"
extension = "redis.so"
;extension = "mongo.so"
extension = "sockets.so"
extension = "swoole.so"
extension = "mongodb.so"
extension = "rdkafka.so"
extension = "exif.so"
extension = "zip.so"
extension = "gd.so"

4、查看 phpinfo() 的 extension_dir，其值：/usr/local/php/lib/php/extensions/no-debug-non-zts-20190902/ ，如图3

5、进入目录：/usr/local/php/lib/php/extensions/no-debug-non-zts-20190902/，查看扩展包，zip、gd 扩展已存在。如图4

-rwxr-xr-x 1 root root   226843 Apr 16 22:48 zip.so

6、决定先还原至上一个基础镜像，在上一个基础镜像中，未安装 zip、gd 扩展，也未报错。检查 /usr/local/php/etc/php.ini 中是否存在 zip。不存在。

;extension = "memcached.so"
extension = "redis.so"
;extension = "mongo.so"
extension = "sockets.so"
extension = "swoole.so"
extension = "mongodb.so"
extension = "rdkafka.so"
extension = "exif.so"

7、进入目录：/usr/local/php/lib/php/extensions/no-debug-non-zts-20190902/，查看扩展包，zip、gd 扩展不存在。如图5

-rwxr-xr-x 1 root root 12372105 Mar 29 23:26 swoole.so

8、最终通过在 Dockerfile 中新增：sed -i ‘/zip.so/d’ /usr/local/php/etc/php.ini && \ 以解决此问题。

RUN sed -i 's/open_basedir = .\/:\/sobey:\/tmp:\/data:\/webtv/;open_basedir = .\/:\/sobey:\/tmp:\/data:\/webtv:\/usr\/local\/php/g' /usr/local/php/etc/php.ini && \
    sed -i 's/allow_url_fopen = Off/allow_url_fopen = On/g' /usr/local/php/etc/php.ini && \
    sed -i 's/disable_functions = exec,system,passthru,shell_exec,escapeshellarg,escapeshellcmd,proc_close,proc_open,dl,popen,show/disable_functions = system,shell_exec,escapeshellarg,escapeshellcmd,dl,popen,show/g' /usr/local/php/etc/php.ini && \
    sed -i 's/max_execution_time = 60/max_execution_time = 300/g' /usr/local/php/etc/php.ini && \
    sed -i 's/;realpath_cache_ttl = 120/realpath_cache_ttl = 1200/g' /usr/local/php/etc/php.ini && \
    sed -i  '/zip.so/d' /usr/local/php/etc/php.ini && \
    sed -i 's/pm.max_children = 20/pm.max_children = 40/g' /usr/local/php/etc/php-fpm.conf

9、检查 /usr/local/php/etc/php.ini 中是否存在 zip。不存在。已经被删除。如图6

图6

10、查看 phpinfo() 的信息，确认 zip 扩展仍然是已经安装。查看 Configure Command，原因在于：’–with-gd’ ‘、’–enable-zip’，zip 扩展默认已经启用。因此，无需要在 php.ini 重新启用。如图7
