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 install gcc 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
