安装部署LNMP/大并发nginx优化/php性能加速 实战
安装部署LNMP及Nginx优化、PHP加速进行压力测试部署LNMP环境：
主机
IP
主机名
Centos7.2
192.168.5.128
www.benet.com
部署步骤如下：
使用yum仓库安装Nginx依赖包
yum -y installgcc gcc-c++ make libtool zlib zlib-devel pcre pcre-devel openssl openssl-devel
创建Nginx用户 组解压Nginx软件包
编译安装Nginx
./configure --prefix=/usr/local/nginx1.10 --with-http_dav_module --with-http_stub_status_module --with-http_addition_module --with-http_sub_module --with-http_flv_module --with-http_mp4_module --with-pcre --with-http_ssl_module --with-http_gzip_static_module --user=nginx --group=nginx && make &&make install
修改配置文件 全部配置文件内容如下：

建立一个软连接 启动Nginx服务 查看端口号是否开启
测试能不能访问到测试页
二进制安装mysql--解压mysql二进制包并且创建用户mysql
删除centos7中带的数据库避免发生冲突
编写配置/etc/my.cnf文件
创建下面的数据文件和log日志文件
添加权限给data文件 并且授予mysql文件为属主属组 创建软连接
初始化mysql
bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
查看log日志中生成的密码 下面登录时会用到
复制启动文件到/etc/init.d/下
登录mysql数据库
使用yum安装php依赖包
需要的安装包例如：
编译安装libmcrypt
编译安装PHP软件包
复制PHP配置文件及设置自启动PHP
修改PHP配置文件
修改/usr/local/php5.6/etc/php.fpm.conf下面几项
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服务
设置防火墙允许9000端口经过
创建PHP测试页
测试是否能访问php页面
测试防盗链 首先在被盗主机上的网页确保有图片 比如：
然后设置域名www.benet.com
设置另一台主机为www.test.com
并且编写盗网页的编码
访问网页看是否能盗 因为在被盗主机www.benet.com中设置了防盗链 这时不能盗
点击链接lianjie查看测试成功是否
测试为成功 防盗链起效
使用yum安装httpd-tools包进行压力测试
测试压力 能够承受多大的压力

编译安装xcache加速PHP
./configure --enable-xcache --enable-xcache-coverager --enable-xcache-optimizer --with-php-config=/usr/local/php5.6/bin/php-config &&make &&make install
编译安装完（就在编译安装后的最后一行）后要记住下面黄色字体
创建xcache缓存文件 把后台管理程序存放到网站根目录下 添加配置文件php.ini
在/etc/php.ini的最后面添加就可以
重启php.ini服务
测试能否打开xcache
进行php动态网页做压力测试
