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/configure.about.php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5：
configure:?error:?Package?requirements?(oniguruma)?were?not?met:
問題5解決：

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(shù)成功

3、編譯源碼
>?make?-j2?#?這里是依賴系統(tǒng)cpu核心數(shù)進行編譯，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
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、獲取默認配置
//?復制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
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
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 參考：https://www.cnblogs.com/xiaozong/p/5724984.html
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
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
