如何在 CentOS 8 中安裝 php-curl？

Question

如何在 CentOS 8 上快速安裝php-curl ？ 它似乎在基礎軟件存儲庫中不可用，甚至在 EPEL 中也不可用。

更新：

[root@example ~]# dnf repolist            
repo id                                 repo name

Answer 1

它可從AppStream存儲庫中的php-common common 獲得，默認情況下應啟用。 確保已啟用它，然后運行：

dnf install php-curl

筆記：
雖然dnf search php-curl不會顯示任何內容，但dnf install php-curl將安裝php-common 。

Answer 2

很晚了，但對於其他有同樣問題的人，我發現這是由於升級 PHP（在我的情況下從 5.6 到 7.2）； 並非所有依賴項都已正確更新。

嘗試通過在 shell 中打開 PHP 進行診斷（只需鍵入php ）。 如果您看到這樣的警告（請注意undefined symbol: curl_pushheader_bynum朝向末尾）：

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

您可能有一個過時版本的 curl 庫。 不知道為什么php-common package 沒有為此設置版本依賴項，因此它得到了升級，但我用dnf update libcurl修復了它。 重新啟動 php/nginx，它已關閉並正在運行！

（注意：如果您不使用dnf ，您應該可以使用yum代替，即yum update libcurl ）

Answer 3

使用以下語法安裝 PHP 擴展很簡單。

sudo yum install php-extension_name

現在您可以使用以下命令為 CentOs 安裝一些常用的php-extensions 。

sudo yum install -y php-dom php-simplexml php-ssh2 php-xml php-xmlreader php-curl php-date php-exif php-filter php-ftp php-gd php-hash php-iconv php-json php-libxml php-pecl-imagick php-mbstring php-mysqlnd php-openssl php-pcre php-posix php-sockets php-spl php-tokenizer php-zlib

Answer 4

對我來說工作只需安裝 curl

#dnf install curl

並重啟 apache

# service httpd restart
