腾讯云实验室:搭建 LNMP 环境
LNMP,表示Linux、Nginx、MySQL、PHP的集合服务器环境,它是基于CentOS/Debian编写的Nginx、PHP、MySQL、phpMyAdmin、eAccelerator一键安装包。可以在云服务器、VPS、独立主机上轻松的安装LNMP生产环境。
Nginx是俄罗斯人编写的十分轻量级的HTTP服务器,它的发音为 “engine X”, 是一个高性能的HTTP和反向代理服务器。在高并发连接的情况下,Nginx是Apache服务器的替代品。Nginx同时也可以作为7层负载均衡服务器来使用。Nginx 0.8.46 + PHP 5.2.14 (FastCGI) 可以承受3万以上的并发连接数,相当于同等环境下Apache的10倍。

一、搭建 Nginx 静态服务器
1. 安装 Nginx
yum install nginx -y
2. 修改 /etc/nginx/conf.d/default.conf
去除对 IPv6 地址的监听,可参考下面的代码示例:
vim /etc/nginx/conf.d/default.conf
server { listen 80 default_server; # listen [::]:80 default_server; server_name _; root /usr/share/nginx/html; # Load configuration files for the default server block. include /etc/nginx/default.d/*.conf; location / { } error_page 404 /404.html; location = /40x.html { } error_page 500 502 503 504 /50x.html; location = /50x.html { } }
3. 启动 Nginx
nginx
4. 查看网页
可访问实验机器外网 HTTP 服务(http://119.29.116.97)来确认是否已经安装成功。
5. 将 Nginx 设置为开机启动
chkconfig nginx on
6. 查看开机启动的所有进程(chkconfig)
# chkconfig abrt-ccpp 0:off 1:off 2:off 3:on 4:off 5:on 6:off abrtd 0:off 1:off 2:off 3:on 4:off 5:on 6:off acpid 0:off 1:off 2:on 3:on 4:on 5:on 6:off atd 0:off 1:off 2:off 3:on 4:on 5:on 6:off auditd 0:off 1:off 2:on 3:on 4:on 5:on 6:off blk-availability 0:off 1:on 2:on 3:on 4:on 5:on 6:off bootlocal 0:off 1:off 2:off 3:on 4:off 5:off 6:off crond 0:off 1:off 2:on 3:on 4:on 5:on 6:off cups 0:off 1:off 2:on 3:on 4:on 5:on 6:off htcacheclean 0:off 1:off 2:off 3:off 4:off 5:off 6:off httpd 0:off 1:off 2:off 3:off 4:off 5:off 6:off ip6tables 0:off 1:off 2:off 3:off 4:off 5:off 6:off iptables 0:off 1:off 2:on 3:on 4:on 5:on 6:off irqbalance 0:off 1:off 2:off 3:off 4:off 5:off 6:off kdump 0:off 1:off 2:on 3:on 4:on 5:on 6:off lvm2-monitor 0:off 1:on 2:on 3:on 4:on 5:on 6:off mdmonitor 0:off 1:off 2:on 3:on 4:on 5:on 6:off messagebus 0:off 1:off 2:on 3:on 4:on 5:on 6:off mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off netconsole 0:off 1:off 2:off 3:off 4:off 5:off 6:off netfs 0:off 1:off 2:off 3:on 4:on 5:on 6:off network 0:off 1:off 2:on 3:on 4:on 5:on 6:off nfs-rdma 0:off 1:off 2:off 3:off 4:off 5:off 6:off nginx 0:off 1:off 2:off 3:off 4:off 5:off 6:off ntpd 0:off 1:off 2:off 3:off 4:off 5:off 6:off ntpdate 0:off 1:off 2:off 3:off 4:off 5:off 6:off php-fpm 0:off 1:off 2:on 3:on 4:on 5:on 6:off portreserve 0:off 1:off 2:on 3:on 4:on 5:on 6:off postfix 0:off 1:off 2:on 3:on 4:on 5:on 6:off psacct 0:off 1:off 2:off 3:off 4:off 5:off 6:off quota_nld 0:off 1:off 2:off 3:off 4:off 5:off 6:off rdisc 0:off 1:off 2:off 3:off 4:off 5:off 6:off rdma 0:off 1:off 2:off 3:off 4:off 5:off 6:off restorecond 0:off 1:off 2:off 3:off 4:off 5:off 6:off rsyslog 0:off 1:off 2:on 3:on 4:on 5:on 6:off saslauthd 0:off 1:off 2:off 3:off 4:off 5:off 6:off sshd 0:off 1:off 2:on 3:on 4:on 5:on 6:off udev-post 0:off 1:on 2:on 3:on 4:on 5:on 6:off
二、安装 MySQL 数据库服务
1. 安装 MySQL
yum -y install mysql-server
MariaDB 官方安装教程:MariaDB 10.2 CentOS repository list
CentOS 7 vim /etc/yum.repos.d/MariaDB-10.2.repo
[mariadb] name = MariaDB baseurl = http://yum.mariadb.org/10.2/centos7-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1
安装命令:
# yum remove MariaDB-server MariaDB-client
yum -y install MariaDB-client MariaDB-server MariaDB-devel
2. 启动 MySQL 服务
service mysqld restart
3. 设置 MySQL 账户 root 密码
/usr/bin/mysqladmin -u root password 'mimvp-demo'
4. 登录MySQL查看数据库
mysql -u root -p'mimvp-demo'
# mysql -u root -p'mimvp-demo' Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 40 Server version: 5.1.73 Source distribution Copyright (c) 2000, 2013, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql> mysql> mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | test | +--------------------+ 3 rows in set (0.28 sec)
5. 将 MySQL 设置为开机自动启动:
chkconfig mysqld on
三、搭建 PHP 环境
1. 安装 PHP
yum -y install php php-fpm php-mysql
注:CentOS 6 默认已经安装了 PHP-FPM 及 PHP-MYSQL,下面命令执行的可能会提示已经安装。
2. 安装之后,启动 PHP-FPM 进程
service php-fpm start
3. 查看启动的端口号
netstat -nlpt | grep php-fpm
启动之后,可以使用下面的命令查看 PHP-FPM 进程监听哪个端口(默认监听9000端口)
netstat -nlpt | grep php-fpm
# netstat -nlpt | grep php-fpm tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 13894/php-fpm
4. 把 PHP-FPM 也设置成开机自动启动:
chkconfig php-fpm on
四、配置 Nginx 并运行 PHP 程序
1. 配置 Nginx
在 /etc/nginx/conf.d 目录中新建一个名为 php.conf 的文件,并配置 Nginx 端口 ,配置示例如下:
vim /etc/nginx/conf.d/php.conf
server { listen 8000; # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 location ~ .php$ { root /usr/share/php; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } }
2. 重启 nginx 服务
service nginx restart
这时候,我们就可以在/usr/share/php 目录下新建一个 info.php 文件来检查 php 是否安装成功了,文件内容参考如下:
vim /usr/share/php/info.php
# cat /usr/share/php/info.php <?php echo phpinfo(); ?>
3. 访问网页
访问 http://119.29.116.97:8000/info.php 可浏览到我们刚刚创建的 info.php 页面了
五、Nginx 应用实例
米扑科技的大多产品,建立在 LNMP 和 LAMP 服务器框架上,示例如下:
