篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了配置一个nginx+php的web服务器相关的知识，希望对你有一定的参考价值。

一、基本信息

系统（L）：CentOS 6.9 #下载地址：http://mirrors.sohu.com
Web服务器(N)：nginx 1.14.0 #下载地址：http://nginx.org/en/download.html
数据库服务器(M)：mysql 5.6.40 #下载地址：https://dev.mysql.com/downloads/mysql
php-FPM服务器(P)：php-5.6.8.tar.gz #下载地址：http://mirrors.sohu.com/php/
OPENSSL：openssl-1.0.2o.tar.gz #下载地址：https://www.openssl.org/source/

指定服务安装的通用位置

mkdir /usr/local/services
SERVICE_PATH=/usr/local/services

创建服务运行的账户

useradd -r -M -s /sbin/nologin www

安装所需依赖包

yum -y install pcre pcre-devel gperftools gcc zlib-devel libxml2 libxml2-devel bzip2 bzip2-devel curl curl-devel libjpeg-devel libjpeg libpng-devel libpng freetype freetype-devel libmcrypt libmcrypt-devel openssl-devel

二、软件安装配置

1、NGINX+OPENSSL安装

下载解压NGINX+OPENSSL

NGINX_URL="http://nginx.org/download/nginx-1.14.0.tar.gz"
OPENSSL_URL="https://www.openssl.org/source/openssl-1.1.0h.tar.gz"

wget -P ${SERVICE_PATH} ${NGINX_URL} && tar -zxvf ${SERVICE_PATH}/nginx*.tar.gz -C ${SERVICE_PATH}
wget -P ${SERVICE_PATH} ${OPENSSL_URL} && tar -zxvf ${SERVICE_PATH}/openssl*.gz -C ${SERVICE_PATH}

编译安装NGINX

cd ${SERVICE_PATH}/nginx-*;./configure --prefix=${SERVICE_PATH}/nginx --user=www --group=www --with-http_stub_status_module --with-http_ssl_module --with-http_flv_module --with-pcre --with-http_gzip_static_module --with-openssl=${SERVICE_PATH}/openssl* --with-http_realip_module --with-google_perftools_module --without-select_module --without-mail_pop3_module --without-mail_imap_module --without-mail_smtp_module --without-poll_module --without-http_autoindex_module --without-http_geo_module --without-http_uwsgi_module --without-http_scgi_module --without-http_memcached_module --with-cc-opt=‘-O2‘ && cd ${SERVICE_PATH}/nginx-*;make && make install

NGINX+OPENSSL安装完成后的清理与其他配置

ln -sv ${SERVICE_PATH}/nginx /usr/local/
rm -rf ${SERVICE_PATH}/nginx/conf/*.default
cd ${SERVICE_PATH} ; rm -rf nginx*.tar.gz openssl*.tar.gz

写入主配置文件nginx.conf（配置已优化）

cat << EOF >/usr/local/nginx/conf/nginx.conf

include vhost/*.conf;
}
EOF

NGINX worker进程数配置，指定为逻辑CPU数量的2倍

THREAD=`expr $(grep process /proc/cpuinfo |wc -l) \* 2`
sed -i s"/WORKERNUMBER/$THREAD/" ${SERVICE_PATH}/nginx/conf/nginx.conf

2、PHP-FPM安装

下载并解压PHP-FPM软件

FPM_URL="http://mirrors.sohu.com/php/php-5.6.8.tar.gz"
wget -P ${SERVICE_PATH} ${FPM_URL} && tar -zxvf ${SERVICE_PATH}/php*.tar.gz -C ${SERVICE_PATH}

编译安装PHP-FPM

cd ${SERVICE_PATH}/php-*;./configure --prefix=${SERVICE_PATH}/php --with-gd --with-mcrypt --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --enable-maintainer-zts --enable-ftp --enable-zip --with-bz2 -with-iconv-dir --with-freetype-dir --with-jpeg-dir --with-png-dir --with-config-file-path=${SERVICE_PATH}/php --enable-mbstring --enable-fpm --with-fpm-user=www --with-fpm-group=www --disable-debug --enable-opcache --enable-soap --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --with-pear --with-gettext --disable-fileinfo && cd ${SERVICE_PATH}/php-*;make && make install

若FPM程序有插件需求，如mongo或redis连接插件，则可通过pecl安装php相关插件

${SERVICE_PATH}/php/bin/pecl install mongo || exit

${SERVICE_PATH}/php/bin/pecl install redis || exit

安装完成后的配置清理

ln -sv ${SERVICE_PATH}/php /usr/local/

三、基于以上配置PHP网站

mkdir /usr/local/nginx/conf/vhost

cat << EOF > /usr/local/nginx/conf/vhost/erbiao.ex.com.conf
server
{
listen 80 backlog=1024;
server_name erbiao.ex.com;
index index.php index.html ;
root /www/web/;
access_log off;
add_header Server-Name WEBerbiaoEX;

location ~ \.php {
fastcgi_pass unix:/dev/shm/php-fpm.sock;
fastcgi_index index.php;
include fastcgi.conf;
set \$real_script_name \$fastcgi_script_name;
if (\$fastcgi_script_name ~ "^(.+?\.php)(/.+)\$") {
set \$real_script_name \$1;
set \$path_info \$2;
}
fastcgi_param SCRIPT_FILENAME \$document_root\$real_script_name;
fastcgi_param SCRIPT_NAME \$real_script_name;
fastcgi_param PATH_INFO \$fastcgi_path_info;


location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 30d;
}

location ~ .*\.(js|css)?$
{
expires 12h;
}

}

}
EOF

若在同一服务器运行nginx和php-fpm，并发量不超过1000，选择unix socket，如此可避免一些检查操作(路由等)，因此更快，更轻。若是高并发业务，则选择使用更可靠的tcp socket，以负载均衡、内核优化等运维手段维持效率

四、启动服务

启动nginx和php-fpm

/usr/local/nginx/sbin/nginx
/usr/local/php-fpm/sbin/php-fpm

命令其他选项

nginx
├── -s选项，向主进程发送信号
|   ├── reload参数，重新加载配置文件
|   ├── stop参数，快速停止nginx
|   ├── reopen参数，重新打开日志文件
|   ├── quit参数，Nginx在退出前完成已经接受的连接请求
├── -t选项，检查配置文件是否正确
├── -c选项，用于指定特定的配置文件并启动nginx
├── -V选项（大写），显示nginx编译选项与版本信息

php-fpm
├── -t选项，检查配置文件是否正确
├── -m选项，显示所有已安装模块
├── -i选项，显示PHP详细信息
├── -v选项，显示版本信息
