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)

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
1

[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'

|
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
1
2
|
# 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
1
2
3
4

|
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
1
2
3
4
|
# 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
