PHP gd JPEG image support missing. PHP gd FreeType support missing.

解決辦法

　　首先重新編譯安裝php

　　安裝之前先編譯安裝JPEG和freetype

安裝jpeg6

[root@localhost /usr/local]# mkdir /usr/local/jpeg6
[root@localhost /usr/local]# mkdir /usr/local/jpeg6/bin
[root@localhost /usr/local]# mkdir /usr/local/jpeg6/lib
[root@localhost /usr/local]# mkdir /usr/local/jpeg6/include
[root@localhost /usr/local]# mkdir -p /usr/local/jpeg6/man/man1

注：此軟件默認不會自動創建所需目錄，故目錄必須手工創建

# yum -y install libtool*
# cd /lnmp/jpeg-6b
# cp /usr/share/libtool/config/config.sub ./
# cp /usr/share/libtool/config/config.guess ./

復制libtool 中的文件，覆蓋jpeg-6b 中的文件

# ./configure --prefix=/usr/local/jpeg6/ --enable-shared --enable-static
# make
# make install

--enable-shared 和 --enable-static 參數分別建立共享庫和靜態庫使用的 libtool

安裝freetype

# cd /lnmp/freetype-2.3.5
# ./configure --prefix=/usr/local/freetype/ --enable-shared
# make
# make install

安裝php

# ./configure --prefix=/usr/local/php/ --with-config-file-path=/usr/local/php/etc/ --with-mysqli=/usr/local/mysql/bin/mysql_config --enable-soap --enable-mbstring=all --enable-sockets --with-pdo-mysql=/usr/local/mysql --with-gd --without-pear --enable-fpm --with-jpeg-dir=/usr/local/jpeg6/ --with-freetype-dir=/usr/local/freetype/ 
# make && make install

別的配置請看：https://www.cnblogs.com/sswind/p/11996629.html

編譯安裝 gd

# cd /lnmp/php-7.3.12/ext/gd/
# /usr/local/php/bin/phpize
# ./configure --with-jpeg-dir=/usr/local/jpeg6/ --with-freetype-dir=/usr/local/freetype --with-php-config=/usr/local/php/bin/php-config
# make && make install

然后將生成的文件，添加至php.ini文件中，路徑會在安裝成功之后輸出

查看是否支持gd“1”表示命令：

/usr/local/php/bin/php -r 'print_r(gd_info());'

# cd /lnmp/php-7.3.12/ext/gettext/
# /usr/local/php/bin/phpize
# ./configure --with-php-config=/usr/local/php/bin/php-config
# make && make install

[root@localhost /usr/local/php/etc]# vim php.ini 
...
extension=/usr/local/php/lib/php/extensions/no-debug-non-zts-20180731/gd.so
extension=/usr/local/php/lib/php/extensions/no-debug-non-zts-20180731/gettext.so
