安装PHP

1、解压-进入目录-生成编译文件

tar -zxvf php-7.4.0.tar.gzcd php-7.4.0./configure --prefix=/usr/local/php /  --with-config-file-scan-dir=/usr/local/php/etc/ /  --with-mhash --with-pdo-mysql /  --with-openssl --with-mysqli /  --with-iconv --with-zlib /  --enable-inline-optimization /  --disable-debug --disable-rpath /  --enable-shared --enable-xml /  --enable-bcmath --enable-shmop /  --enable-sysvsem --enable-sysvshm --enable-mbregex /  --enable-mbstring --enable-ftp /  --enable-pcntl --enable-sockets /  --with-xmlrpc --enable-soap /  --without-pear --with-gettext /  --enable-session --with-curl /  --enable-opcache --enable-fpm /  --without-gdbm --enable-fast-install /  --disable-fileinfo --with-sodium

2、编译 并 安装

make && make install

3、配置文件

1.复制配置文件到安装目录

cp ~/php-7.4.0/php.ini-production /usr/local/php/etc/php.inicp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.confcp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf

2.修改PHP 配置文件 php.ini

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

内容修改如下：

;不显示错误，默认display_errors = Off;在关闭display_errors后开启PHP错误日志（路径在php-fpm.conf中配置），默认log_errors = On;字符集，默认default_charset = "UTF-8";文件上传大小，默认值太小，建议修改10Mupload_max_filesize = 2M;Maximum size of POST data that PHP will accept. 表单最大值，默认是8M，如果表单含有多图上传，大小可能不够。超过该大小后台收不到 表单数据post_max_size = 8M;设置PHP的扩展库路径，默认被注释了，之后一个文件夹 于 你/usr/local/php/lib/php/extensions/ 下的文件夹同名。extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20151012/";设置PHP的时区date.timezone = PRC;开启opcache，默认是0[opcache]; Determines if Zend OPCache is enabledopcache.enable=1

3.修改php-fpm 的配置文件 php-fpm.conf

vim /usr/local/php/etc/php-fpm.conf

内容修改如下

; 去掉里分号，方便以后重启。建议修改;Default Value: none; 下面的值最终目录是/usr/local/php/var/run/php-fpm.pid; 开启后可以平滑重启php-fpmpid = run/php-fpm.pid; 设置错误日志的路径，可以默认值; Note: the default prefix is /usr/local/php/var; Default Value: log/php-fpm.log, 即/usr/local/php/var/log/php-fpm.logerror_log = /var/log/php-fpm/error.log; Log等级，可以默认值; Possible Values: alert, error, warning, notice, debug; Default Value: noticelog_level = notice; 后台运行，默认yes，可以默认值; Default Value: yes;daemonize = yes; 引入www.conf文件中的配置，可以默认值include=/usr/local/php/etc/php-fpm.d/*.conf
