8 月 1 日 PHP 释出了 7.3.8 稳定版本。昨天折腾好了 Nginx 今天就来升级 PHP 吧！其实是昨天弄了好久都没成功今天才成功了

备份当前 PHP

为了避免翻车，先对当前的 PHP 安装目录进行备份：

root@castle:~# which php
/usr/local/php/bin/php

cp -r /usr/local/php /usr/local/php_backup

获取当前 PHP 编译参数

为了避免新装的 PHP 缺少已经在使用的功能造成错误，需要使用以前编译的相同参数（当然也可以加上新的参数）进行全新编译。

# From https://stackoverflow.com/questions/9520957/get-current-php-install-settings
php -i | head -n 10

我的 PHP 是 Oneinstack 一键包安装的，输出的参数如下：

phpinfo()
PHP Version => 7.3.6

System => Linux castle 4.15.0-54-generic #58-Ubuntu SMP Mon Jun 24 10:55:24 UTC 2019 x86_64
Build Date => Jul 3 2019 14:18:49
Configure Command => ‘./configure’ ‘–prefix=/usr/local/php’ ‘–with-config-file-path=/usr/local/php/etc’ ‘–with-config-file-scan-dir=/usr/local/php/etc/php.d’ ‘–with-fpm-user=www’ ‘–with-fpm-group=www’ ‘–enable-fpm’ ‘–disable-opcache’ ‘–disable-fileinfo’ ‘–enable-mysqlnd’ ‘–with-mysqli=mysqlnd’ ‘–with-pdo-mysql=mysqlnd’ ‘–with-iconv-dir=/usr/local’ ‘–with-freetype-dir’ ‘–with-jpeg-dir’ ‘–with-png-dir’ ‘–with-zlib’ ‘–with-libxml-dir=/usr’ ‘–enable-xml’ ‘–disable-rpath’ ‘–enable-bcmath’ ‘–enable-shmop’ ‘–enable-exif’ ‘–enable-sysvsem’ ‘–enable-inline-optimization’ ‘–with-curl=/usr/local/curl’ ‘–enable-mbregex’ ‘–enable-mbstring’ ‘–with-password-argon2’ ‘–with-sodium=/usr/local’ ‘–with-gd’ ‘–with-openssl=/usr/local/openssl’ ‘–with-mhash’ ‘–enable-pcntl’ ‘–enable-sockets’ ‘–with-xmlrpc’ ‘–enable-ftp’ ‘–enable-intl’ ‘–with-xsl’ ‘–with-gettext’ ‘–enable-zip’ ‘–without-libzip’ ‘–enable-soap’ ‘–disable-debug’
Server API => Command Line Interface
Virtual Directory Support => disabled
Configuration File (php.ini) Path => /usr/local/php/etc
Loaded Configuration File => /usr/local/php/etc/php.ini

由于输出的编译参数是带 ‘’ 的，复制到代码编辑器里把 ‘ 替换掉就可以了。

仔细阅读编译参数，看是否有需要外部库的部分，确认各种 DIR 参数是否有相应目录，例如

ls /usr/local/openssl
bin  cert.pem  certs  include  lib  man  misc  openssl.cnf  private

下载 PHP 源码

新建临时文件夹，在 https://www.php.net/downloads.php 页面下载 PHP 的最新 Stable 版本，解压缩，进入源码目录。

cd ~ && mkdir php_temp && cd php_temp
wget https://www.php.net/distributions/php-7.3.8.tar.gz
tar -xzf php-7.3.8.tar.gz
cd php-7.3.8

开始编译

确认编译参数无误以后开始编译。

./configure  --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-config-file-scan-dir=/usr/local/php/etc/php.d --with-fpm-user=www --with-fpm-group=www --enable-fpm --disable-opcache --disable-fileinfo --enable-mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-iconv-dir=/usr/local --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-exif --enable-sysvsem --enable-inline-optimization --with-curl=/usr/local/curl --enable-mbregex --enable-mbstring --with-password-argon2 --with-sodium=/usr/local --with-gd --with-openssl=/usr/local/openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-ftp --enable-intl --with-xsl --with-gettext --enable-zip --without-libzip --enable-soap --disable-debug

如果没有出错，大概可以看到这样的输出：

此时可以先执行 make 命令；但是这一步在我的机器上有出错，错误如下：

ext/xmlrpc/libxmlrpc/encodings.o: In function `convert':
/root/php_temp/php-7.3.8/ext/xmlrpc/libxmlrpc/encodings.c:65: undefined reference to `libiconv_open'

collect2: error: ld returned 1 exit status
Makefile:293: recipe for target 'sapi/cli/php' failed
make: *** [sapi/cli/php] Error 1

搜索以后，根据 https://fukun.org/archives/10102487.html 里的命令解决了问题：

make ZEND_EXTRA_LIBS=’-liconv’

make 就成功了：

Build complete.
Don’t forget to run ‘make test’.

最后执行 make install 即可完成编译：

使用 php -v 命令查看当前 PHP 版本：

升级成功了；最后重启 PHP 以应用更改。

service php-fpm restart
