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./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(shù)成功+--------------------------------------------------------------------+

Thank you for using PHP.

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

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

5、添加環(huán)境變量> vim /etc/profile # 在文件末尾加入

# 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

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(kuò)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

7、開機(jī)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(jī)自動執(zhí)行php-fpm開機(jī)自啟動腳本

> reboot # 重啟，ssh重連

# 重啟后

[root@54skyer ~]# netstat -ntlp

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(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(kuò)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
