web网站——nginx,LNMP部署03

nginx功能:

(1)web服务器:

默认网页目录为:/usr/share/nginx/html

 

(2)反向代理服务器:

       nginx代替客户端访问后端服务器,后端服务器只知道是nginx的请求,并将结果返回给 nginx,nginx 在返回给客户端结果

找到nginx配置文件中 location,配置段如下,默认是空的参数

location / {
}

做反向代理,/ 后面加上虚拟路径名字,下面用 proxy_pass 模块和上游的服务器的url,例如:

location /node1 {
        proxy_pass http://192.168.210.131/;
        }

 

(3)负载均衡服务器:

        nginx 负责转发客户端的请求,轮询到的后端服务器获得的是客户端的访问请求,服务器直接返回给客户端结果       先配置 location 中的反向代理,将客户端请求发送到一个集群(zn为集群名,可以随便起),然后用 upstream 模块声明集群,并写入后端的真实server的地址,例如:

    include /etc/nginx/conf.d/*.conf;
    upstream zn {
    server 192.168.210.132 weight=2 max_fails=2 fail_timeout=2;
    server 192.168.210.131 weight=1 max_fails=2 fail_timeout=2;
    }
    server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  _;
        root         /usr/share/nginx/html;
        index        index.php index.html;
        # Load configuration files for the default server block.
#        include /etc/nginx/default.d/*.conf;

        location / {
        proxy_pass http://zn/;
        }

 

(4)动态页面配置

配置源:

[root@node1 yum.repos.d]# cat cdrom.repo epel.repo 
[cdrom]
name=centos base
enabled=1
gpgcheck=0
baseurl=http://mirrors.163.com/centos/7/os/x86_64/
[epel]
name=Extra Packages for Enterprise Linux 7 - $basearch
baseurl=http://mirrors.aliyun.com/epel/7/$basearch
failovermethod=priority
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
 
[epel-debuginfo]
name=Extra Packages for Enterprise Linux 7 - $basearch - Debug
baseurl=http://mirrors.aliyun.com/epel/7/$basearch/debug
failovermethod=priority
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
gpgcheck=0
 
[epel-source]
name=Extra Packages for Enterprise Linux 7 - $basearch - Source
baseurl=http://mirrors.aliyun.com/epel/7/SRPMS
failovermethod=priority
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
gpgcheck=0

安装软件动态网站所需软件包:

yum install nginx php php-mysql mariadb-server mariadb php-gd -y

修改server段配置

    server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  _;
        #root         /usr/share/nginx/html;
        root         /date/wordpress;
        index index.php index.html;  #添加index.php默认页

        # Load configuration files for the default server block.
        #include /etc/nginx/default.d/*.conf; 注释掉

        location ~ php$ {
        fastcgi_pass 127.0.0.1:9000;  #php-fpm监听的地址
        include fastcgi.conf;   #加载fastcgi文件
        }

        error_page 404 /404.html;
            location = /40x.html {
        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }
