一、nginx帮助参数
下面是关于/application/nginx/sbin/nginx 的参数帮助 [[email protected] conf]# /application/nginx/sbin/nginx -h nginx version: nginx/1.6.3 Usage: nginx [-?hvVtq] [-s signal] [-c filename] [-p prefix] [-g directives] Options: -?,-h : this help -v : show version and exit -V : show version and configure options then exit -t : test configuration and exit -q : suppress non-error messages during configuration testing -s signal : send signal to a master process: stop, quit, reopen, reload -p prefix : set prefix path (default: /application/nginx-1.6.3/) -c filename : set configuration file (default: conf/nginx.conf) -g directives : set global directives out of configuration file
重启要学脚本，检查api端口，如果没问题就重启，如果有问题恢复到原来的模式
二、利用include功能优化nginx的配置文件
1 2.1、由于nginx主配置文件工作的时候会有很多虚拟主机维护不方便，因此会做出下面的
2 先创建一个目录 mkdir /application/nginx/conf//extra
3 之后备份 cp nginx.conf nginx.conf.basename1
4 删除server标签，添加include
5 # Vim nginx.conf
6 worker_processes 1;
7 events {
8 worker_connections 1024;
9 }
10 http {
11 include mime.types;
12 default_type application/octet-stream;
13 sendfile on;
14 keepalive_timeout 65;
15 include extra/www.conf; --》这里添加include
16 include extra/bbs.conf
17 }
18
19 复制nginx配置文件到extra下面
20 [[email protected] conf]# cp nginx.conf.pyrene.20170320V1 extra/a
21 2.2、查找出虚拟主机的代码，然后添加到上面include创建extra/www,conf 等等文件中
22 [[email protected] extra]# sed -n "10,17p" a
23 server {
24 listen 80;
25 server_name www.cnblogs.co;
26 location / {
27 root html/www;
28 index index.html index.htm;
29 }
30 }
31 [[email protected] extra]# sed -n "18,25p" a
32 server {
33 listen 80;
34 server_name bbs.cnblogs.co;
35 location / {
36 root html/bbs;
37 index index.html index.htm;
38 }
39 }
40 [[email protected] extra]# sed -n "10,17p" a >www.conf
41 [[email protected] extra]# sed -n "18,25p" a >bbs.conf
42 这样就生成了两个虚拟主机
43 2.3、由于/etc/hosts里面有域名，就不用解析
44
45
46 [[email protected] conf]# /application/nginx/sbin/nginx -t →检查语法
47 nginx: the configuration file /application/nginx-1.6.3/conf/nginx.conf syntax is ok
48 nginx: configuration file /application/nginx-1.6.3/conf/nginx.conf test is successful
49
50 [[email protected] conf]# /application/nginx/sbin/nginx -s reload →重启
51
52 [[email protected] conf]# curl www.cnblogs.co →查看是否成功
53 www.cnblogs.com/pyrene/
三、nginx细腻主机别名配置
1 1、 虚拟主机别名介绍及配置
2 所谓虚拟主机别名，就是为虚拟主机设置出了主域名意外的一个域名
3 方法：直接在配置文件中域名哪里直接添加一个新的域名，然后域名和域名之间要用空格隔开
4 如：
5 1、[[email protected] extra]# vim www.conf
6
7 server {
8 listen 80;
9 server_name www.cnblogs.co pyrene; --》添加别名 别名之间空格就可以
10 location / {
11 root html/www;
12 index index.html index.htm;
13 }
14 }
15 2、[[email protected] extra]# vim bbs.conf
16
17 server {
18 listen 80;
19 server_name bbs.cnblogs.co cnblog.co; --》添加别名
20 location / {
21 root html/bbs;
22 index index.html index.htm;
23 }
24 }
25
26
27
28 2、把域名写道/etc/hosts解析
29
30 [[email protected] conf]# vim /etc/hosts
31
32 [[email protected] extra]# cat /etc/hosts
33 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
34 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
35 10.0.0.8 www.cnblogs.co bbs.cnblogs.co cnblog.co pyrene
36
37 3、然后检查语法，重启关闭防火墙，curl 查看就可以
38 [[email protected] extra]# curl -I pyrene
39 HTTP/1.1 200 OK
40 Server: nginx/1.8.1
41 Date: Sat, 04 Mar 2017 07:06:57 GMT
42 Content-Type: text/html
43 Content-Length: 24
44 Last-Modified: Fri, 03 Mar 2017 18:52:40 GMT
45 Connection: keep-alive
46 ETag: "58b9bb78-18"
47 Accept-Ranges: bytes
48 别名除了可以方便搜索之外，监控服务器里面监控别名，可以很好的判断每一台机器是否正常
四、Nginx状态信息配置
1 编译的时候制定了一个状态模块 —with-http_stub_status_module 显示nginx当先的状态
2 配置如下：
3
4 1、选择虚拟主机的方式增加了一个server标签到/application/nginx/conf/extra/status.conf里面，起名status.etiantian.org
5 cat >>/application/nginx/conf/extra/status.conf<<EOF
6 ##status
7 server{
8 listen 80;
9 server_name status.cnblogs.co;
10 location / {
11 stub_status on;
12 access_log off;
13 }
14 }
15 EOF
16
17 server_name status. status.cnblog.co; →这里添加的域名 标签
18
19 2、需要包含,include
20 [[email protected] conf]# vim nginx.conf
21
22 worker_processes 1;
23 events {
24 worker_connections 1024;
25 }
26 http {
27 include mime.types;
28 default_type application/octet-stream;
29 sendfile on;
30 keepalive_timeout 65;
31 #nginx vhosts config
32 include extra/www.conf;
33 include extra/bbs.conf;
34 include extra/blog.conf;
35 include extra/status.conf; →这里的包含
36 }
37 3、在/etc/hosts里面解析
38 [[email protected] conf]# vim /etc/hosts
39 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
40 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
41 10.0.0.8 www.cnblogs.co bbs.cnblogs.co cnblog.co pyrene. status.cnblog.co →这里就是解析
42 4、在window中解析配置 并且重启nginx
5、查看
浏览器中出现
[[email protected] conf]# curl status.cnblog.co
Active connections: 1 →查看连接数
server accepts handled requests
16 16 16
Reading: 0 Writing: 1 Waiting: 0
上面的详细讲解
Active connections:2872
#<==表示Nginx 正处理的活动连接数 2872个
