1.php编译安装前解决依赖包
yum -y install epel-release yum -y install gcc gcc-c++ make pcre pcre-devel zlib zlib-devel openssl openssl-devel libxml2 libxml2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel openldap openldap-devel libmcrypt libmcrypt-devel sqlite sqlite-devel oniguruma-devel oniguruma
2.源码编译安装php
./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --enable-ctype --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-freetype-dir --with-jpeg-dir --with-png-dir --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-ldap-sasl --with-xmlrpc --enable-zip --enable-soap --with-gettext --enable-fpm make && make install
# 在/usr/local/php/etc目录下，默认是没有php.ini这个配置文件的，需要拷贝一个过去。 # 拷贝的文件路径/usr/local/src/php-7.4.7 cp /usr/local/src/php-7.4.7/php.ini-production /usr/local/php/etc/php.ini
3.php编译安装说明
--prefix 指定php的安装目录 --with-config-file-path 指定php的配置文件位置 --with-mysql 让php可以操作mysql --enable-fpm 主要是nginx要来调用php语言使得php-fpm
4.启动php-fpm
# 环境变量 export PATH=$PATH:/usr/local/php/sbin/:/usr/local/php/bin/ # 检查配置文件 php-fpm -t # 使用默认配置文件 mv /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf # 查看php-fpm的listen配置
5.验证php-fpm的启动
1.进程
2.端口
3.日志
6.使用systemctl管理php-fpm
# 创建配置文件的路径 vi /usr/lib/systemd/system/php-fpm.service # 配置内容： [Unit] Description=php-fpm After=network.target [Service] Type=forking ExecStart=/usr/local/php/sbin/php-fpm [Install] WantedBy=multi-user.target
7.nginx默认配置无法处理php程序，只会下载，需要改配置文件nginx.conf
# 写一个test.php测试 <?php echo "hello world"; ?>
8.nginx+php-fpm结合的配置
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
# 修改默认的/scripts为$document_root,去root->html下面找页面
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
9.页面test.php访问测试
常见问题：
1、运行systemctl start php-fpm报错
[30-Jun-2020 18:34:23] WARNING: Nothing matches the include pattern ‘/usr/local/php/etc/php-fpm.d/*.conf‘ from /usr/local/php/etc/php-fpm.conf at line 125.

解决方法：
