安裝部署LNMP及Nginx優化、PHP加速進行壓力測試

部署LNMP環境：

部署步驟如下：

使用yum倉庫安裝Nginx依賴包

yum -y install gcc gcc-c++ make libtool zlib zlib-devel pcre pcre-devel openssl openssl-devel

創建Nginx用戶 組解壓Nginx軟件包

編譯安裝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 全部配置文件內容如下：

}

建立一個軟連接 啟動Nginx服務 查看端口號是否開啟

測試能不能訪問到測試頁

二進制安裝mysql--解壓mysql二進制包並且創建用戶mysql

刪除centos7中帶的數據庫避免發生沖突

編寫配置/etc/my.cnf文件

創建下面的數據文件和log日誌文件

添加權限給data文件 並且授予mysql文件為屬主屬組 創建軟連接

初始化mysql

bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

查看log日誌中生成的密碼 下面登錄時會用到

復制啟動文件到/etc/init.d/下

登錄mysql數據庫

使用yum安裝php依賴包

需要的安裝包例如：

編譯安裝libmcrypt

編譯安裝PHP軟件包

復制PHP配置文件及設置自啟動PHP

修改PHP配置文件

修改/usr/local/php5.6/etc/php.fpm.conf下面幾項

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

啟動PHP服務

設置防火墻允許9000端口經過

創建PHP測試頁

測試是否能訪問php頁面

測試防盜鏈 首先在被盜主機上的網頁確保有圖片 比如：

然後設置域名www.benet.com

設置另一臺主機為www.test.com

並且編寫盜網頁的編碼

訪問網頁看是否能盜 因為在被盜主機www.benet.com中設置了防盜鏈 這時不能盜

點擊鏈接lianjie查看測試成功是否

測試為成功 防盜鏈起效

使用yum安裝httpd-tools包進行壓力測試

測試壓力 能夠承受多大的壓力

編譯安裝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

編譯安裝完（就在編譯安裝後的最後一行）後要記住下面黃色字體

創建xcache緩存文件 把後臺管理程序存放到網站根目錄下 添加配置文件php.ini

在/etc/php.ini的最後面添加就可以

重啟php.ini服務

測試能否打開xcache

進行php動態網頁做壓力測試
