Linux安装PHP8

Linux下安装PHP8环境

安装编译环境

安装编译环境依赖包

yum -y install gcc gcc-c++ glibc automake autoconf libtool make

安装编译 php 依赖库

yum -y install libxslt-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5-devel libidn libidn-devel openssl openssl-devel sqlite-devel libcurl-devel libpng-devel libjpeg-devel freetype-devel libicu-devel oniguruma-devel libxslt-devel

下载PHP包

wget https://www.php.net/distributions/php-8.1.9.tar.gz

tar -xzxvf php-8.1.9.tar.gz

配置PHP环境

./configure \
    --prefix=/usr/local/php8 \
    --with-config-file-path=/usr/local/php8 \
    --with-config-file-scan-dir=/usr/local/php8/php.d \

    --enable-session \
    --with-curl \
    --with-jpeg-dir \
    --with-freetype-dir \
    --enable-opcache

编译安装 php

采用两个核心编译

make -j 2 && make install

PHP配置文件编辑

php.ini

创建php.ini配置文件

cp php.ini-production /usr/local/php8/etc/php.ini

修改php.ini配置文件

vim /usr/local/php8/etc/php.ini

session.save_path = "/tmp" #将注释打开

php-fpm

设置php-fpm配置文件

cd /usr/local/php8/etc

cp php-fpm.conf.default php-fpm.conf

vim php-fpm.conf

将注释取消并修改

pid = /var/run/php-fpm.pid

php-fpm参数优化

cd /usr/local/php8/etc/php-fpm.d/

cp www.conf.default www.conf

删除文件中;的注释和空格

sed -i '/^;.*/d;/^$/d'  www.conf

删除文件中的 #注释

sed -i '/#.*/d' www.conf

优化后

[www]
user = nginx
group = nginx
listen = 127.0.0.1:9000 #php本机不用改，分开则加
；listen.allowed_clients=nginx Ip地址 #nginx和php同一个机器不用加
pm.max_children = 100
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35

创建php-fpm执行用户

创建nginx用户
增加nginx用户，并修改nginx服务的默认用户

useradd nginx -s /sbin/nologin -M

php-fpm相关命令

php-fpm 启动与检查

启动php-fpm

/usr/local/php8/sbin/php-fpm

检查 php-fpm 是否成功启动

ps aux | grep php-fpm

php-fpm 环境变量配置

配置 php-fpm 系统环境变量

vim /etc/profile.d/php.sh

export PHP_HOME=/usr/local/php8
export PATH=$PATH:$PHP_HOME/bin:$PHP_HOME/sbin

source /etc/profile.d/php.sh

php-fpm 开机自启动

配置 php-fpm 开机自启动

vim /lib/systemd/system/php-fpm.service

[Unit]
Description=php-fpm
After=network.target
[Service]
Type=forking
ExecStart=/usr/local/php8/sbin/php-fpm
ExecStop=/bin/pkill -9 php-fpm
PrivateTmp=true
[Install]
WantedBy=multi-user.target

systemctl daemon-reload

停止 php-fpm

pkill php-fpm

用 systemctl 启动 php-fpm

systemctl start php-fpm.service

设置 php-fpm 开机启动

systemctl enable php-fpm.service

php-fpm 其他管理命令

systemctl stop php-fpm.service 			# 停止服务
systemctl restart php-fpm.service 		# 重新启动服务
systemctl status php-fpm.service		# 查看服务当前状态
systemctl disable php-fpm.service 		# 停止开机自启动

Nginx 配置支持PHP

nginx一招配置，帮你快速隐藏php后缀名

配置文件

server
{
	listen 80;
	server_name localhost;
	index index.html index.htm index.php;
	root /usr/local/nginx/html;

        location / {
                try_files $uri $uri/ $uri.php$is_args$args;
        }

	location ~ \.php$
	{

                if ($request_uri ~ ^/([^?]*)\.php($|\?)) {   
                  return 302 /$1$is_args$args; 
                }

		include fastcgi_params;        #指定nginx连接php-fpm的常量
		fastcgi_pass 127.0.0.1:9000;    #连接php-fpm的地址和端口
		fastcgi_index index.php;        #指定默认页面
		fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name; #指定站点根目录
	}
}

验证文件

cd /usr/local/nginx/html/

vim index.php

<?php
phpinfo();
?>

重启php-frm

systemctl restart php-fpm.service

重载nginx

systemctl reload nginx

/usr/local/nginx/sbin/./nginx -t

访问验证

http://127.0.0.1:80/index.php

nginx启动报错

解决nginx启动报错nginx: [emerg] open() “/var/run/nginx/nginx.pid“ failed (2: No such file or directory)

采取方法一

接口错误响应

PHP出现“headers already sent”原因及解决方案

错入日志：
Warning: Cannot modify header information - headers already sent by ***

检查是否使用windows下的notepad编辑修改了php文件,php不支持UTF8编码文件的BOM头，当php文件头部出现BOM时候会导致内容被发送。
