mysql：https://blog.csdn.net/qq_40200087/article/details/89479137

nginx：https://blog.csdn.net/qq_40200087/article/details/89504980

下载：https://www.php.net/downloads.php#v7.3.4

开发工具：

 yum groupinstall "Development Tools" -y

安装依赖：

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

解压：

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

进入到/usr/local 并修改名字

cd /usr/local  mv php-7.3.xxx  php7.3

编译

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

编译完成后是以下样子  +--------------------------------------------------------------------+ | License:                                                           | | This software is subject to the PHP License, available in this     | | distribution in the file LICENSE.

安装：

make && make install

复制以下三个配置文件

cp php.ini-production /usr/local/php/etc/php.ini  cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf  cp /usr/local/php/etc/php-fpm.d/www.conf.default  /usr/local/php/etc/php-fpm.d/www.conf

设置php.ini

#注意：php的注释为 ; 如果设置前面有 ; ,请记得删除 ; vim /usr/local/php/etc/php.ini  max_execution_time = 300 max_input_time = 300 memory_limit = 128M post_max_size = 16M upload_max_filesize = 2M date.timezone = Asia/Shanghai

测试php是否安装成功

/usr/local/php/sbin/php-fpm -t

拷贝启动文件

cp /usr/local/php7.3/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

赋予执行权限

chmod 755 /etc/init.d/php-fpm

启动

service php-fpm start

查询是否启动成功

ps -ef |grep php-fpm  root      27332      1  0 08:51 ?        00:00:00 php-fpm: master process (/usr/local/php/etc/php-fpm.conf) mysql     27333  27332  0 08:51 ?        00:00:00 php-fpm: pool www mysql     27334  27332  0 08:51 ?        00:00:00 php-fpm: pool www root      27336   7898  0 08:51 pts/1    00:00:00 grep --color=auto php-fpm

配置 nginx可解析 .php文件

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 / {             try_files $uri $uri/ /index.php?$args;         }           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;         }

测试是否解析成功：

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

遇到一个错误：

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
