      一步步教你如何搭建php8環(huán)境(附常見問題解決辦法)

      本篇文章由php8教程欄目給大家詳細(xì)介紹如何一步步搭建php8環(huán)境,希望對大家有所幫助。

      一、下載

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

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

      二、解壓、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、配置編譯參數(shù),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
      登錄后復(fù)制

      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.

      配置編譯參數(shù)成功

      3、編譯源碼

      > make -j2 # 這里是依賴系統(tǒng)cpu核心數(shù)進(jìn)行編譯,對性能有一定提升,通常利用核心數(shù)不要超過一半,

      4、安裝

      make install
      登錄后復(fù)制

      安裝成功

      [root@54skyer php-8.0.0]# make install Installing shared extensions:     /usr/local/php8/lib/php/extensions/no-debug-non-zts-20200930/ Installing PHP CLI binary:        /usr/local/php8/bin/ Installing PHP CLI man page:      /usr/local/php8/php/man/man1/ Installing PHP FPM binary:        /usr/local/php8/sbin/ Installing PHP FPM defconfig:     /usr/local/php8/etc/ Installing PHP FPM man page:      /usr/local/php8/php/man/man8/ Installing PHP FPM status page:   /usr/local/php8/php/php/fpm/ Installing phpdbg binary:         /usr/local/php8/bin/ Installing phpdbg man page:       /usr/local/php8/php/man/man1/ Installing PHP CGI binary:        /usr/local/php8/bin/ Installing PHP CGI man page:      /usr/local/php8/php/man/man1/ Installing build environment:     /usr/local/php8/lib/php/build/ Installing header files:          /usr/local/php8/include/php/ Installing helper programs:       /usr/local/php8/bin/   program: phpize   program: php-config Installing man pages:             /usr/local/php8/php/man/man1/   page: phpize.1   page: php-config.1 /usr/local/src/php-8.0.0/build/shtool install -c ext/phar/phar.phar /usr/local/php8/bin/phar.phar ln -s -f phar.phar /usr/local/php8/bin/phar Installing PDO headers:           /usr/local/php8/include/php/ext/pdo/

      5、添加環(huán)境變量

      > 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 # 獲得如下信息  php -v PHP 8.0.0 (cli) (built: Dec 15 2020 02:46:59) ( NTS ) Copyright (c) The PHP Group Zend Engine v4.0.0-dev, Copyright (c) Zend Technologies

      6、獲取默認(rèn)配置

      // 復(fù)制php.ini到編譯配置參數(shù)指定的目錄。php.ini在解壓的源碼目錄里 > cp /usr/local/src/php-8.0.0/php.ini-production /usr/local/php8/etc/php.ini // 復(fù)制一份php-fpm的配置模版文件到同級目錄 方便備份和修改 > cp /usr/local/php8/etc/php-fpm.conf.default /usr/local/php8/etc/php-fpm.conf // 復(fù)制一份php-fpm的擴展配置模板文件到同級目錄 方便備份和修改 > cp /usr/local/php8/etc/php-fpm.d/www.conf.default /usr/local/php8/etc/php-fpm.d/www.conf // 復(fù)制開啟自起腳本到系統(tǒng)啟動自動加載腳本目錄。fpm/init.d.php-fpm在解壓的源碼目錄里 > cp /usr/local/src/php-8.0.0/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
      登錄后復(fù)制

      7、開機自啟動

      設(shè)置命令可被執(zhí)行

      > chmod +x /etc/init.d/php-fpm # 添加可執(zhí)行權(quán)限
      登錄后復(fù)制

      檢驗自啟動腳本

      > service php-fpm start # 檢驗服務(wù)啟動 > service php-fpm stop # 檢驗服務(wù)關(guān)閉 // 均正常提示 > chkconfig php-fpm on # 設(shè)置開機自動執(zhí)行php-fpm開機自啟動腳本 > reboot # 重啟,ssh重連 # 重啟后 [root@54skyer ~]# netstat -ntlp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name     tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      1097/nginx: master   tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      1061/sshd            tcp        0      0 0.0.0.0:16379           0.0.0.0:*               LISTEN      1090/redis-server 0  tcp        0      0 127.0.0.1:9000          0.0.0.0:*               LISTEN      1083/php-fpm: maste

      7、額外說明

      關(guān)于配置文件的一些說明

      php-fpm.conf是PHP-FPM特有的配置文件

      php.ini是所有php模式中必須的配置文件

      兩者的區(qū)別是,php-fpm.conf是PHP-FPM進(jìn)程管理器的配置文件,php.ini是PHP解析器的配置文件

      有的PHP版本的配置文件路徑中還有/fpm.d/www.conf配置文件

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

      ; include=fpm.d/*.conf
      登錄后復(fù)制

      我們可以使用php-fpm.conf配置慢日志

      我們是可以開啟慢日志功能的。

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