如何安装Php7.3

 yum groupinstall "Development Tools" -y

yum install libxml2-devel -y

yum install bzip2 bzip2-devel -y 

yum install curl-devel -y

yum install libjpeg-devel -y

yum install libpng libpng-devel -y

yum install freetype-devel -y

yum install libxslt-devel -y 

yum install libzip-devel  -y


或者合到一起安装
yum install libxml2-devel bzip2 bzip2-devel curl-devel libjpeg-devel libpng libpng-devel freetype-devel libxslt-devel libzip-devel -y

tar -zxvf php-xxx.tar.gz -C /usr/local/

cd /usr/local

mv php-7.3.xxx  php7.3

cd /usr/local/php7.3 

./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-fpm-user=mysql --with-fpm-group=mysql --with-curl --with-freetype-dir --with-gd --with-gettext --with-iconv-dir --with-kerberos --with-libdir=lib64 --with-libxml-dir --with-mysqli=mysqlnd --with-openssl --with-pcre-regex --with-pdo-mysql=mysqlnd --with-mysql=mysqlnd --with-pdo-sqlite --with-pear --with-png-dir --with-jpeg-dir --with-xmlrpc --with-xsl --with-zlib --with-bz2 --with-mhash --enable-fpm --enable-bcmath --enable-libxml --enable-inline-optimization --enable-mbregex --enable-mbstring --enable-opcache --enable-pcntl --enable-shmop --enable-soap --enable-sockets --enable-sysvsem --enable-sysvshm --enable-xml --enable-fpm

注意：fastcgi_pass 127.0.0.1:9000; 端口与/usr/local/php/etc/php-fpm.d/www.conf 里面的listen = 127.0.0.1:9000 配置要一样，不然无法解析


vim /usr/local/nginx/conf/nginx.conf 修改server{} 这个里面的数据为：

        listen       80;
        server_name  localhost;

        access_log  /usr/local/nginx/logs/host.access.log;
        root /usr/local/nginx/html;
        index  index.html index.htm index.php;
        location / {

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        location ~ \.php$ {
            expires -1s;
            try_files $uri =404;
            fastcgi_pass 127.0.0.1:9000;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include fastcgi.conf;
        }

在/usr/local/nginx/html中创建test.php，里面内容如下

<?php
 phpinfo();
?>

执行 /usr/local/nginx/sbin/nginx

浏览去输入 http://本机ip/test.php

如果打开网页了则解析成功，如果是下载，则解析失败

执行测试的时候遇到

[root@jenkins-master etc]# /usr/local/php/sbin/php-fpm -t
PHP:  syntax error, unexpected '=' in Unknown on line 1
[25-Apr-2019 08:36:28] ERROR: Unable to include /usr/local/php/etc/php-fpm.d/www.conf from /usr/local/php/etc/php-fpm.conf at line 23
[25-Apr-2019 08:36:28] ERROR: failed to load configuration file '/usr/local/php/etc/php-fpm.conf'
[25-Apr-2019 08:36:28] ERROR: FPM initialization failed



最后发现是我执行./configue 的时候后面配置文件有一个少了个空格，我已修改上面的配置

原因呢是因为 www.conf 里面的user配置错误
