部署流程
备份chupinxiu.com.conf配置文件
在web1上创建负载切换的lua文件：/opt/openresty-1.13.6.1/lua/php-fpm-upstream.lua
if ngx.var.project == "apipro" then
return ngx.exec("@single")
else
return ngx.exec("@mutiple")
end
编辑nginx配置文件: /opt/openresty-1.13.6.1/nginx/conf/vhost/chupinxiu.com.conf
配置两个php的upstream
upstream php-fpm-backend-mutiple {
server unix:/var/run/php-fpm.sock weight=5; # web1
server 10.135.216.41:9000 weight=5; # web2
}
upstream php-fpm-backend-single {
server unix:/var/run/php-fpm.sock; # web1
}
为两个upstream配置两个location
location @mutiple {
root $dest;
proxy_set_header Host $host;
fastcgi_pass php-fpm-backend-mutiple;
fastcgi_index index.php;
include fastcgi.conf;
}
location @single {
root $dest;
proxy_set_header Host $host;
fastcgi_pass php-fpm-backend-single;
fastcgi_index index.php;
include fastcgi.conf;
}
normal location中使用php-fpm-upstream.lua选择upstream
location @normal {
content_by_lua_file /opt/openresty-1.13.6.1/lua/php-fpm-upstream.lua;
}
重启nginx
