这篇文章主要介绍Centos中如何安装PHP7.4和Nginx，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！

准备

1、下载所需安装包

wget https://www.php.net/distributions/php-7.4.0.tar.gz
wget http://nginx.org/download/nginx-1.17.6.tar.gz

2、安装所需扩展

yum install -y gcc gcc-c++ make cmake bison autoconf wget lrzsz libtool libtool-ltdl-devel freetype-devel libjpeg.x86_64 libjpeg-devel libpng-devel gd-devel python-devel patch sudo openssl* openssl openssl-devel ncurses-devel bzip* bzip2 unzip zlib-devel libevent* libxml* libxml2-devel libcurl* curl-devel readline-devel sqlite-devel libsodium-devel https://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/o/oniguruma-5.9.5-3.el7.x86_64.rpm https://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/o/oniguruma-devel-5.9.5-3.el7.x86_64.rpm

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

4.修改 www.conf

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

内容修改如下：

; 设置用户和用户组，默认都是nobody。可以默认值user = nginxgroup = nginx; 设置PHP监听; 下面是默认值，不建议使用。可以默认值listen = 127.0.0.1:9000; 根据nginx.conf中的配置fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;;listen = /var/run/php-fpm/php-fpm.sock######开启慢日志。可以默认值slowlog = /var/log/php-fpm/$pool-slow.logrequest_slowlog_timeout = 10s

4、php-fpm 操作

/usr/local/php/sbin/php-fpm -t    # php-fpm检测配置文件是否正确/usr/local/php/sbin/php-fpm     # php-fpm启动kill -INT `cat /usr/local/php/var/run/php-fpm.pid`   # php-fpm关闭kill -USR2 `cat /usr/local/php/var/run/php-fpm.pid`   #php-fpm平滑重启

安装nginx

1、解压-进入目录-生成编译文件

tar -zxvf nginx-1.17.6.tar.gzcd nginx-1.17.6./configure \  --prefix=/usr/local/nginx \  --with-http_stub_status_module \  --with-http_ssl_module \  --with-http_realip_module \  --with-http_sub_module \  --with-http_gzip_static_module \  --with-pcre

2、编译 && 安装

makemake install

测试一下 /usr/local/nginx/sbin/nginx -t

nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful #测试成功

3、配置文件

1.配置 nginx.conf,执行 vim /usr/local/nginx/conf/nginx.conf

内容修改如下

#user nobody;worker_processes 1;error_log /www/logs/nginx/error.log;error_log /www/logs/nginx/error_notice.log notice;#error_log logs/error.log info;#pid    logs/nginx.pid;events {  worker_connections 1024;}http {  include    mime.types;  default_type application/octet-stream;  #access_log logs/access.log main;  sendfile    on;  #tcp_nopush   on;  #keepalive_timeout 0;  keepalive_timeout 65;  #gzip on;  #显示目录  #autoindex on;  #显示文件大小  #autoindex_exact_size on;  #显示文件时间  #autoindex_localtime on;  include /www/conf/vhosts/*.conf;}

2.添加网站配置文件

vim /www/conf/vhosts/default.conf

文件内容如下

server{  listen 80;  server_name localhost,www.test.com;  root /www/web/default;  location / {    #开启 url 美化    if (!-e $request_filename){      rewrite ^/(.*) /index.php last;    }    index index.html index.php;  }  location ~ \.php$ {    include fastcgi.conf;    fastcgi_pass 127.0.0.1:9000;    try_files $uri = 404;  }}

4、测试 配置

运行 /usr/local/nginx/sbin/nginx -t，若测试失败，返回检查执行步骤是否有错误

5、nginx 操作

/usr/local/nginx/sbin/nginx -t     # 检测配置文件是否正确/usr/local/nginx/sbin/nginx       # 启动/usr/local/nginx/sbin/nginx -s stop   # 关闭/usr/local/nginx/sbin/nginx -s reload  #平滑重启
