nginx基础配置

来源：互联网发布：易语言串口接收数据编辑：程序博客网时间：2024/06/11 08:07

1.安装 nginx

在安装之前首先要安装pcre-7.9.tar.gz
    # tar zxvf pcre-7.9.tar.gz
    # cd pcre-7.9
    # ./configure
    # make && make install

安装nginx
     # tar zxvf nginx-0.7.61.tar.gz
    # cd nginx-0.7.61
    # ./configure --with-http_stub_status_module --prefix=/usr/local/nginx
    # make && make install

修改nginx的配置文件

我这里是把原先的重命名然后新建了一个nginx.conf

检查nginx的配置文件

# /usr/local/webserver/nginx/sbin/nginx -t

启动nginx

# /usr/local/webserver/nginx/sbin/nginx

重启nginx

# kill -HUP `cat /usr/local/nginx/logs/nginx.pid`

(1)查看负载均衡信息

location /nginx

Unknown macro: { stub_status on; access_log on; auth_basic "NginxStatus"; auth_basic_user_file /usr/local/nginx/htpasswd; }

其中/usr/local/nginx/htpasswd可以用apache自带的功能生成｡

最后在IE里访问:

http://www.tenddata.com/nginx, 然后输入用户名密码就进入了｡

进入之后的说明

输入地址 http://www.tenddata.com/nginx/,输入验证帐号密码,即可看到类似如下内容:

    Active connections: 328
    server accepts handled requests
    9309 8982   28890
    Reading: 1 Writing: 3 Waiting: 324

第一行表示目前活跃的连接数

第三行的第三个数字表示Nginx运行到当前时间接受到的总请求数,如果快达到了上限,就需要加大上限值了｡

第四行是Nginx的队列状态

(2)负载均衡

upstream backend

Unknown macro: { server 192.168.100.89}
