原始的 nginx 配置
upstream service_test {
server 127.0.0.1:8080;
}
server
{
listen 80;
server_name test.com;
index index.html index.php;
root /tmp/test.com;
error_page 404 http://test.com/404.html;
error_page 502 http://test.com/502.html;
error_page 500 http://test.com/500.html;
location ~* \.(gif|jpg|jpeg|png|css|js|ico|txt|svg|woff|ttf|eot)$
{
rewrite ^(.*)$ /static$1 break;
root /tmp/test.com; #
expires 1d;
}
location ~* \.(html|htm)$
{
rewrite ^(.*)$ /static$1 break;
roo /tmp/test.com; #
expires 900s;
}
location / {
proxy_pass http://service_test;
include /opt/conf/nginx/proxy.conf;
}
修改后的 Nginx 配置
upstream service_test {
server 127.0.0.1:8080;
}
server
{
listen 80;
server_name test.com;
index index.html index.php;
root /tmp/test.com;
error_page 404 http://test.com/404.html;
error_page 502 http://test.com/502.html;
error_page 500 http://test.com/500.html;
location ~* \.(gif|jpg|jpeg|png|css|js|ico|txt|svg|woff|ttf|eot)$
{
rewrite ^(.*)$ /static$1 break;
root /tmp/test.com; #
expires 1d;
}
location ~* \.(html|htm)$
{
rewrite ^(.*)$ /static$1 break;
roo /tmp/test.com; #
expires 900s;
}
set $flag 0;
if ($request_uri ~* "^/fuck/\w+\.html$") {
set $flag "${flag}1";
}
if ($remote_addr !~* "192.168.0.50|192.168.0.51|192.168.0.56") {
set $flag "${flag}2";
}
if ($flag = "012") {
rewrite ^ /index.html permanent;
}
location / {
proxy_pass http://service_test;
include /opt/conf/nginx/proxy.conf;
}
在实现需求的过程中出现的问题
把 if 指令 和 proxy_pass 都放在 location 下面的话，if 指令里面的内容不会执行，只会执行 proxy_pass。
location / { if ($remote_addr !~* "192.168.0.50|192.168.0.51|192.168.0.56") { rewrite ^ /index.html permanent; } proxy_pass http://service_test; include /opt/conf/nginx/proxy.conf;}
if 指令下面使用 proxy_pass 指令问题
像下面这样使用会报错，错误的方式：
if ($remote_addr ~* "192.168.0.50|192.168.0.51|192.168.0.56") {
proxy_pass http://test.com/fuck;
}
正确的方式：
if ($remote_addr ~* "192.168.0.50|192.168.0.51|192.168.0.56") {
proxy_pass http://test.com$request_uri;
}
或是
if ($remote_addr ~* "192.168.0.50|192.168.0.51|192.168.0.56") {
proxy_pass http://test.com;
}
如果你是直接另外启动一个 location 的话，比如启动如下 location ：
location /fund { if ($remote_addr !~* "192.168.0.50|192.168.0.51|192.168.0.56") {
rewrite ^ /index.html permanent;
} }
这样的方式也是不支持的，当用 IP 192.168.0.50 访问的时候，没有达到我们的业务需求，会报错 400
