php网站怎么实现负载均衡

这篇文章主要介绍“php网站怎么实现负载均衡”的相关知识，小编通过实际案例向大家展示操作过程，操作方法简单快捷，实用性强，希望这篇“php网站怎么实现负载均衡”文章能帮助大家解决问题。 php网站实现负载均衡的方法：1、准备好虚拟机；2、通过yum方式安装php；3、加入配置“pid = /usr/local/php-fpm/var/run/php-fpm.pid”；4、通过yum方式安装nginx；5、编写nginx启动脚本，添加配置为“NGINX_SBIN=”/usr/local/nginx/sbin/nginx””。本教程操作环境：linux5.9.8系统、PHP8.1版、DELL G3电脑nginx+php 实现代理与负载均衡（1台nginx，2台php）实验准备 3台虚拟机


192.168.239.136/192.168.239.140/192.168.239.144

1 安装php 192.168.239.140/192.168.239.144安装之前先做好这些准备工作（安装基础环境）

下载php源码包到 /usr/local/src cd /usr/local/src
解压 cd 解压免费云主机域名目录 useradd -s /sbin/nologin php-fpm


./configure--prefix=/usr/local/php--with-config-file-path=/usr/local/php/etc--enable-fpm--with-fpm-user=php-fpm--with-fpm-group=php-fpm--with-mysql=mysqlnd--with-libxml-dir--with-gd--with-jpeg-dir--with-png-dir--with-freetype-dir--with-iconv-dir--with-zlib-dir--with-mcrypt--enable-soap--enable-gd-native-ttf--enable-ftp--enable-mbstring--enable-exif--enable-zend-multibyte--disable-ipv6--with-pear--with-curl
make&&makeinstall
cpphp.ini-development/usr/local/php-fpm/etc/php.ini拷贝配置文件
cpsapi/fpm/init.d.php-fpm/etc/init.d/php-fpm拷贝启动脚本
mv/usr/local/php-fpm/etc/php-fpm.conf.default/usr/local/php-fpm/etc/php-fpm.conf
>/usr/local/php-fpm/etc/php-fpm.conf
vim!$加入如下配置
[global]
pid=/usr/local/php-fpm/var/run/php-fpm.piderror_log=/usr/local/php-fpm/var/log/php-fpm.log
[www]listen=192.168.239.140:9000（IP是php本机IP或者0.0.0.0，不能是127.0.0.1）user=php-fpmgroup=php-fpmlisten.owner=nobodylisten.group=nobodypm=dynamicpm.max_children=50pm.start_servers=20pm.min_spare_servers=5pm.max_spare_servers=35pm.max_requests=500rlimit_files=1024
slowlog=/usr/local/php-fpm/var/slow.logrequest_slowlog_timeout=1
php_admin_value[open_basedir]=/data/www/:/tmp/
/usr/local/php-fpm/sbin/php-fpm-t
chmod755/etc/init.d/php-fpm
/etc/init.d/php-fpmstartnetstat-lnpt查看是否有监听192.168.239.140：9000
mkdir-p/tmp/tmp
vim/tmp/tmp/index.php创建动态测试文件，写入如下
dongtaiqingqiu1

2.第二台安装php （安装编译都不变，配置文件IP更改为 192.168.239.144：9000 最后index.php 中dongtaiqingqiu 1改为dongtaiqingqiu2 ）3.安装nginx下载源码包到 /usr/local/src cd /usr/local/src
wget http://nginx.org/download/nginx-1.6.2.tar.gz
解压 cd 解压目录


yuminstall-ypcre-devel
./configure--prefix=/usr/local/nginx--with-pcre
make
makeinstall

4. 编写nginx启动脚本


vim/etc/init.d/nginx加入如下配置
#!/bin/bash
#chkconfig:-3021
#description:httpservice.
#SourceFunctionLibrary
./etc/init.d/functions
#NginxSettings
NGINX_SBIN="/usr/local/nginx/sbin/nginx"
NGINX_CONF="/usr/local/nginx/conf/nginx.conf"
NGINX_PID="/usr/local/nginx/logs/nginx.pid"
RETVAL=0
prog="Nginx"
start(){
echo-n$"Starting$prog:"
mkdir-p/dev/shm/nginx_temp
daemon$NGINX_SBIN-c$NGINX_CONF
RETVAL=$?
echo
return$RETVAL
}
stop(){
echo-n$"Stopping$prog:"
killproc-p$NGINX_PID$NGINX_SBIN-TERM
rm-rf/dev/shm/nginx_temp
RETVAL=$?
echo
return$RETVAL
}
reload(){
echo-n$"Reloading$prog:"
killproc-p$NGINX_PID$NGINX_SBIN-HUP
RETVAL=$?
echo
return$RETVAL
}
restart(){
stop
start
}
configtest(){
$NGINX_SBIN-c$NGINX_CONF-t
return0
}
case"$1"in
start)
start
;;
stop)
stop
;;
reload)
reload
;;
restart)
restart
;;
configtest)
configtest
;;
*)
echo$"Usage:$0{start|stop|reload|restart|configtest}"
RETVAL=1
esac
exit$RETVAL

保存后，执行


chmoda+x/etc/init.d/nginx或者chmod755！$修改权限
servicenginxstart启动nginx

5. 配置反向代理


>/usr/local/nginx/conf/nginx.conf
vim/usr/local/nginx/conf/nginx.conf加入如下配置
usernobodynobody;
worker_processes2;
error_log/usr/local/nginx/logs/nginx_error.logcrit;
pid/usr/local/nginx/logs/nginx.pid;
worker_rlimit_nofile51200;
events
{
useepoll;
worker_connections6000;
}
http
{

server_names_hash_max_size4096;
log_formatcombined_realip'$remote_addr$http_x_forwarded_for[$time_local]'

fastcgi_temp_path/usr/local/nginx/fastcgi_temp;

gzip_buffers48k;
gzip_comp_level5;
gzip_http_version1.1;
gzip_typestext/plainapplication/x-javascripttext/csstext/htmapplication/xml;
includevhosts/*.conf;
}

配置代理


mkdir/usr/local/nginx/conf/vhosts
vi/usr/local/nginx/conf/vhosts/php.conf加入如下配置
upstreammysvr{
#weigth参数表示权值，权值越高被分配到的几率越大
server192.168.239.144:9000weight=2;
server192.168.239.140:9000weight=1;
}
server
{
listen80;
server_namewww.q.com;
indexindex.htmlindex.htmindex.php;
root/usr/local/nginx/html;
location~.php${
includefastcgi_params;
fastcgi_passmysvr;
fastcgi_indexindex.php;
fastcgi_paramSCRIPT_FILENAME/tmp/tmp$fastcgi_script_name;
}
}
/usr/local/nginx/sbin/nginx-t检测配置文件
/usr/local/nginx/sbin/nginx-sreload（直接重新加载配置，不需要重启）
vim/usr/local/nginx/html/1.html创建静态测试文件，写入
jingtaifangwen

设置本地解析修改windons hosts（地址 c:windowssystem32driversetchosts）记事本打开，最下面添加一行配置


192.168.239.136www.q.com

测试：最好用谷歌浏览器（如下显示代理成功）访问 www.q.com 显示的是nginx 默认页访问 www.q.com/.html 显示的jingtaifangwen访问 www.q.com/index.php 多刷新几次会显示 dongtaifangwen1 一次 dongtaifangwen2 两次关于“php网站怎么实现负载均衡”的内容就介绍到这里了，感谢大家的阅读。如果想了解更多行业相关的知识，可以关注百云主机行业资讯频道，小编每天都会为大家更新不同的知识点。
