一步步教你如何搭建php8環境（附常見問題解決方法）

這篇文章由php8教學專欄給大家詳細介紹如何一步一步搭建php8環境，希望對大家有幫助。

一、下載

1、https://www.php.net/distributions/php-8.0.0.tar.gz下載到本機，檔案傳輸上傳到/usr/local /src/

2、wget -P /usr/local/src/ https://www.php.net/distributions/php-8.0.0.tar.gz

#二、解壓縮、編譯、安裝

1、解壓縮

> cd /usr/local/src/
> tar xzf php-8.0.0.tar.gz
> cd php-8.0.0

2、設定編譯參數，參考https://www.php.net/manual/zh... 選擇自己需要的選項

./configure --prefix=/usr/local/php8 --with-config-file-path=/usr/local/php8/etc --with-fpm-user=www --with-fpm-group=www --with-curl --with-openssl --with-mysqli --with-pdo-mysql --with-iconv --with-mhash --with-zlib  --enable-mbstring  --enable-gd   --enable-gd-jis-conv --enable-sockets --enable-fpm --enable- --enable-xml  --enable-pdo  --enable-cli --enable-pcntl --enable-soap --enable-opcache --enable-fileinfo --disable-rpath --enable-mysqlnd --with-zip --enable-simplexml --with-libxml --with-sqlite3 --with-pdo-sqlite --enable-phar --enable-tokenizer --enable-cgi

問題1：

configure: error: Package requirements (libxml-2.0 >= 2.9.0) were not met:
Package 'libxml-2.0', required by 'virtual:world', not found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables LIBXML_CFLAGS
and LIBXML_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

問題1解決：

> yum install libxml2-devel

問題2：

configure: error: Package requirements (sqlite3 > 3.7.4) were not met:

問題2解決：##

> yum install sqlite-devel

問題3：

configure: error: Package requirements (libcurl >= 7.29.0) were not met:

問題3解決：

> yum install libcurl-devel

問題4：

configure: error: Package requirements (libpng) were not met:

問題4解決：

> yum install libpng libpng-devel

問題5：

configure: error: Package requirements (oniguruma) were not met:

問題5解決：

> cd /usr/local/src/
> wget http://ftp.altlinux.org/pub/distributions/ALTLinux/Sisyphus/x86_64/RPMS.classic/liboniguruma5-6.9.6-alt1.x86_64.rpm -O liboniguruma5-6.9.6-alt1.x86_64.rpm
> rpm -ivh liboniguruma5-6.9.6-alt1.x86_64.rpm
> wget http://ftp.altlinux.org/pub/distributions/ALTLinux/Sisyphus/x86_64/RPMS.classic/liboniguruma-devel-6.9.6-alt1.x86_64.rpm -O liboniguruma-devel-6.9.6-alt1.x86_64.rpm 
> rpm liboniguruma-devel-6.9.6-alt1.x86_64.rpmcli

問題6：

configure: error: Package requirements (libzip >= 0.11 libzip != 1.3.1 libzip != 1.7.0) were not met:

問題6解決：

> yum install libzip libzip-devel

配置編譯參數成功

Thank you for using PHP.

3、編譯原始碼

> make -j2 # 這裡是依賴系統cpu核心數進行編譯，對效能有一定提升，通常利用核心數不要超過一半，

4、安裝

make install

安裝成功

[root@54skyer php-8.0.0]# make install

ln -s -f phar.phar /usr/local/php8/bin/phar
Installing PDO headers:           /usr/local/php8/include/php/ext/pdo/

5、新增環境變數

> vim /etc/profile # 在文件末尾加入
# PATH=$PATH:/usr/local/php8/bin/
# export PATH
# :wq 保存并退出
> source /etc/profile # 立刻生效配置
> php -v # 获得如下信息

php -v
PHP 8.0.0 (cli) (built: Dec 15 2020 02:46:59) ( NTS )

Zend Engine v4.0.0-dev, Copyright (c) Zend Technologies

6、取得預設設定

// 复制php.ini到编译配置参数指定的目录。php.ini在解压的源码目录里
> cp /usr/local/src/php-8.0.0/php.ini-production /usr/local/php8/etc/php.ini
// 复制一份php-fpm的配置模版文件到同级目录 方便备份和修改
> cp /usr/local/php8/etc/php-fpm.conf.default /usr/local/php8/etc/php-fpm.conf
// 复制一份php-fpm的扩展配置模板文件到同级目录 方便备份和修改
> cp /usr/local/php8/etc/php-fpm.d/www.conf.default /usr/local/php8/etc/php-fpm.d/www.conf
// 复制开启自起脚本到系统启动自动加载脚本目录。fpm/init.d.php-fpm在解压的源码目录里
> cp /usr/local/src/php-8.0.0/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

7、開機自啟動

設定指令可執行

> chmod +x /etc/init.d/php-fpm # 添加可执行权限

檢驗自啟動腳本

> service php-fpm start # 检验服务启动
> service php-fpm stop # 检验服务关闭
// 均正常提示
> chkconfig php-fpm on # 设置开机自动执行php-fpm开机自启动脚本
> reboot # 重启，ssh重连
# 重启后
[root@54skyer ~]# netstat -ntlp

7、額外說明

關於設定檔的一些說明

php-fpm.conf是PHP-FPM特有的設定檔

php.ini是所有php模式中必須的設定檔

兩者的差異是，php-fpm.conf是PHP-FPM進程管理器的設定文件，php. ini是PHP解析器的設定檔

有的PHP版本的設定檔路徑中還有/fpm.d/www.conf設定檔

這是php-fpm.conf設定的文件的擴展文件，可以打開php-fpm.conf文件查看

; include=fpm.d/*.conf

我們可以使用php-fpm.conf配置慢日誌

#我們是可以開啟慢日誌功能的。

slowlog = /usr/local/var/log/php-fpm.log.slow
request_slowlog_timeout = 5s
