一、下载

1、https://www.php.net/distributions/php-8.0.0.tar.gz下载到本地，文件传输上传到 /usr/local/src/

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

二、解压、编译、安装

1、解压缩> cd /usr/local/src/

> tar xzf php-8.0.0.tar.gz

> cd php-8.0.0

2、配置编译参数，参考https://www.php.net/manual/zh/configure.about.php选择自己需要的选项./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

问题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.

问题1解决：> yum install libxml2-devel

问题2：configure: error: Package requirements (sqlite3 > 3.7.4) were not met:

问题2解决：> yum install sqlite-devel

问题3：configure: error: Package requirements (libcurl >= 7.29.0) were not met:

问题3解决：> yum install libcurl-devel

问题4：configure: error: Package requirements (libpng) were not met:

问题4解决：> yum install libpng libpng-devel

问题5：configure: error: Package requirements (oniguruma) were not met:

问题5解决：> 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

问题6：configure: error: Package requirements (libzip >= 0.11 libzip != 1.3.1 libzip != 1.7.0) were not met:

问题6解决：> yum install libzip libzip-devel

Thank you for using PHP.

3、编译源码> make -j2 # 这里是依赖系统cpu核心数进行编译，对性能有一定提升，通常利用核心数不要超过一半，

4、安装make install

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

5、添加环境变量> 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 # 获得如下信息

php -v

6、获取默认配置// 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、开机自启动

设置命令可被执行> chmod +x /etc/init.d/php-fpm # 添加可执行权限

检验自启动脚本> 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、额外说明

关于配置文件的一些说明 参考：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模式中必须的配置文件

两者的区别是，php-fpm.conf是PHP-FPM进程管理器的配置文件，php.ini是PHP解析器的配置文件

有的PHP版本的配置文件路径中还有/fpm.d/www.conf配置文件

这是php-fpm.conf配置的文件的扩展文件，可以打开php-fpm.conf文件查看

; include=fpm.d/*.conf

我们可以使用php-fpm.conf配置慢日志

我们是可以开启慢日志功能的。

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

request_slowlog_timeout = 5s
