LNMP的部署优化及压测
1、安装php
(1)解决依赖关系
[root@www ~]# yum -y install libxml2-devel libcurl-devel openssl-devel bzip2-devel
安装libmcrypt
[root@www ~]# tar zxf libmcrypt-2.5.7.tar.gz
[root@wwwr ~]# cd libmcrypt-2.5.7/
[root@www libmcrypt-2.5.7]# ./configure –prefix=/usr/local/libmcrypt && make && make install
(2)编译安装php
[root@www ~]# tar zxf php-5.6.27.tar.gz
[root@www ~]# cd php-5.6.27/
[root@www php-5.6.27]# ./configure –prefix=/usr/local/php5.6 –with-mysql=mysqlnd –with-pdo-mysql=mysqlnd –with-mysqli=mysqlnd –with-openssl –enable-fpm –enable-sockets –enable-sysvshm –enable-mbstring –with-freetype-dir –with-jpeg-dir –with-png-dir –with-zlib –with-libxml-dir=/usr –enable-xml –with-mhash –with-mcrypt=/usr/local/libmcrypt –with-config-file-path=/etc –with-config-file-scan-dir=/etc/php.d –with-bz2–enable-maintainer-zts
[root@www php-5.6.27]# make&& make install
(3)提供php配置文件
[root@www php-5.6.27]# cp php.ini-production /etc /php.ini
(4)为php-fpm提供脚本
[root@www php-5.6.27]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
[root@www php-5.6.27]# chmod +x /etc/init.d/php-fpm
[root@www php-5.6.27]# chkconfig –add php-fpm
[root@www php-5.6.27]# chkconfig php-fpm on
(5)提供php-fpm配置文件并编辑：
# cp /usr/local/php5.6/etc/php-fpm.conf.default /usr/local/php5.6/etc/php-fpm.conf
[root@www ~]# vi /usr/local/php5.6/etc/php-fpm.conf
修改内容如下：
pid = run/php-fpm.pid
listen = 0.0.0.0:9000
pm.max_children =300
pm.start_servers =20
pm.min_spare_servers = 20
pm.max_spare_servers = 100
启动php-fpm服务：
[root@www ~]# service php-fpm start
Starting php-fpm done
[root@www ~]# netstat -anpt | grep php-fpm
tcp 0 0 0.0.0.0:9000 0.0.0.0:* LISTEN 25456/php-fpm: mast
[root@www ~]# firewall-cmd –permanent –add-port=9000/tcp
success
[root@www ~]# firewall-cmd –reload
Success
在nginx.conf文件的server中添加下面内容支持php
location ~ .*\.(php|php5)?$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
fastcgi_cache cache_fastcgi;
fastcgi_cache_valid 200 302 1h;
fastcgi_cache_valid 301 1d;

fastcgi_cache_min_uses 1;
fastcgi_cache_use_stale error timeout invalid_header http_500;
fastcgi_cache_key http://$host$request_uri;
}

#

location = /50x.html {
root html;
}
}
}
重载nginx服务
[root@www ~]# /usr/local/nginx1.10/sbin/nginx -s reload
三、验证、压力测试
(1)验证防盗链
使用apache做为一个测试站点，域名为www.test.com，在测试页上做一个超链接，链接nginx站点的一张图片
[root@centos1 ~]# cat /var/www/html/index.html
<a href=”http://www.benet.com/11.gif”>lianjie</a>
Nginx站点的网页目录结如下
tree /usr/local/nginx1.10/html/
/usr/local/nginx1.10/html/
├── 11.gif
├── 50x.html
├── img
│ └── nolink.jpg
├── index.html
├── test.php
在客户端浏览器中输入www.test.com (注意域名解析和防火墙)
点击页面链接
从上图可以看到防盗链设置生效了
(2)验证gzip功能
使用谷歌浏览器测试访问，如下图显示结果：（提示：在访问测试页之前按F12键）
用户访问test.php文件，在上图中content-encoding:gzip表明响应给用户的数据是压缩传输。
(3)压力测试
安装httpd-tools软件包
[root@www ~]# yum -y install httpd-tools
[root@www ~]# ab -c 500 -n 50000 http://www.benet.com/index.html

(5)xcache加速php
安装xcache
wget http://xcache.lighttpd.net/pub/Releases/3.2.0/xcache-3.2.0.tar.gz #下载
[root@www ~]# tar zxf xcache-3.2.0.tar.gz #解压
[root@www ~]# cd xcache-3.2.0/ #进入安装目录
[root@www xcache-3.2.0]# /usr/local/php5.6/bin/phpize#用phpize生成configure配置文件
[root@www xcache-3.2.0]# ./configure –enable-xcache –enable-xcache-coverager –enable-xcache-optimizer –with-php-config=/usr/local/php5.6/bin/php-config #配置
[root@www xcache-3.2.0]# make && make install #编译、安装
Installing shared extensions:
/usr/local/php5.6/lib/php/extensions/no-debug-zts-20131226/
安装完成之后，出现下面的界面，记住以下路径，后面会用到
/usr/local/php5.6/lib/php/extensions/no-debug-zts-20131226/
2）创建xcache缓存文件
# touch /tmp/xcache
# chmod 777 /tmp/xcache
3）拷贝xcache后台管理程序到网站根目录
[root@www xcache-3.2.0]# cp -r htdocs/ /usr/local/nginx1.10/html/xcache
4）配置php支持xcache
vi / etc/php.ini #编辑配置文件，在最后一行添加以下内容
[xcache-common]
extension = /usr/local/php5.6/lib/php/extensions/no-debug-zts-20131226/xcache.so
[xcache.admin]
xcache.admin.enable_auth = Off
[xcache]
xcache.shm_scheme =”mmap”
xcache.size=60M
xcache.count =1
xcache.slots =8K
xcache.ttl=0
xcache.gc_interval =0
xcache.var_size=64M
xcache.var_count =1
xcache.var_slots =8K
xcache.var_ttl=0
xcache.var_maxttl=0
xcache.var_gc_interval =300
xcache.test =Off
xcache.readonly_protection = Off
xcache.mmap_path =”/tmp/xcache”
xcache.coredump_directory =””
xcache.cacher =On
xcache.stat=On
xcache.optimizer =Off
[xcache.coverager]
xcache.coverager =On
xcache.coveragedump_directory =””
测试
service php-fpm restart #重启php-fpm
浏览器打开网站根目录下面的xcache
http://http://www.benet.com/xcache可以看到如下页面：
