LNMP架構介紹

 

12.一、LNMP架構介紹

• 和LAMP不一樣的是，提供web服務的是Nginx
• 而且php是做爲一個獨立的服務存在的，這個服務叫作php-fpm
• Nginx直接處理靜態請求，動態請求會轉發給php-fpm

 

12.二、MySQL安裝

• cd /usr/local/src
•  wget http://mirrors.sohu.com/mysql/MySQL-5.6/mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz 
•  tar zxvf mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz
•  mv mysql-5.6.35-linux-glibc2.5-x86_64 /usr/local/mysql
•  cd /usr/local/mysql
•  useradd mysql
•  mkdir /data/
•  ./scripts/mysql_install_db --user=mysql --datadir=/data/mysql
•  cp support-files/my-default.cnf  /etc/my.cnf 
•  cp support-files/mysql.server /etc/init.d/mysqld
•  vi /etc/init.d/mysqld
• 定義basedir和datadir
•  /etc/init.d/mysqld start

 

[root@zgxlinux-01 src]# rm -rf /usr/local/mysql/

[root@zgxlinux-01 src]# rm -rf /etc/init.d/mysqld 

[root@zgxlinux-01 src]# tar mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz

[root@zgxlinux-01 src]# mv mysql-5.6.39-linux-glibc2.12-x86_64 /usr/local/mysql

[root@zgxlinux-01 src]# ls /usr/local/mysql/

12.三、PHP安裝

• 和LAMP安裝PHP方法有差異，須要開啓php-fpm服務
•  cd /usr/local/src/
•  wget http://cn2.php.net/distributions/php-5.6.30.tar.gz
•  tar zxf php-5.6.30.tar.gz
•  useradd -s /sbin/nologin php-fpm
•  cd php-5.6.30
•  ./configure --prefix=/usr/local/php-fpm --with-config-file-path=/usr/local/php-fpm/etc --enable-fpm --with-fpm-user=php-fpm --with-fpm-group=php-fpm --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-pdo-mysql=/usr/local/mysql --with-mysql-sock=/tmp/mysql.sock --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 --with-pear --with-curl  --with-openssl
• make && make install
•  cp php.ini-production /usr/local/php-fpm/etc/php.ini
•  vi /usr/local/php/etc/php-fpm.conf //寫入以下內容（參考https://coding.net/u/aminglinux/p/aminglinux-book/git/blob/master/D15Z/php-fpm.conf）
•  cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
•  chmod 755 /etc/init.d/php-fpm
•  chkconfig --add php-fpm
•  chkconfig php-fpm on
•  service php-fpm start
•  ps aux |grep php-fpm

12.五、Nginx介紹

• Nginx官網 nginx.org，最新版1.13，最新穩定版1.12 
•  Nginx應用場景：web服務、反向代理、負載均衡
•  Nginx著名分支，淘寶基於Nginx開發的Tengine，使用上和Nginx一致，服務名，配置文件名都同樣，和Nginx的最大區別在於Tenging增長了一些定製化模塊，在安全限速方面表現突出，另外它支持對js，css合併
•  Nginx核心+lua相關的組件和模塊組成了一個支持lua的高性能web容器openresty，參考http://jinnianshilongnian.iteye.com/blog/2280928
