目标
测试tengine 动态upstream的功能,为后续动态升级提供服务支持
该功能实时修改内存数据,无需reload
环境
- centos 7 mini版
- java 1.8 运行两个测试程序分别监听7079和7080端口
- tengine2.1.2 最新版本已经去除动态upstream功能
安装步骤
安装基础环境
jemalloc-4.4.0.tar.bz2
wget https://github.com/jemalloc/jemalloc/releases/download/4.4.0/jemalloc-4.4.0.tar.bz2
yum install bzip2
tar xjf jemalloc-4.4.0.tar.bz2
cd jemalloc-4.4.0
./configure
make && make install
echo '/usr/local/lib' > /etc/ld.so.conf.d/local.conf
ldconfig
yum install gcc openssl-devel gd-devel pcre-devel libxml2-devel libxslt-devel GeoIP-devel perl-devel lua-devel -y
tengine安装
wget http://tengine.taobao.org/download/tengine-2.1.2.tar.gz
tar -zxvf tengine-2.1.2.tar.gz
cd tengine-2.1.2
./configure --prefix=/root/web/nginx/tengine --enable-mods-static=all --with-http_upstream_check_module --with-http_v2_module --with-http_dyups_module --with-http_dyups_lua_api --with-http_sysguard_module
make && make install
tengine 配置
nginx.conf
user nobody;
worker_processes 2;
error_log logs/error.log debug;
pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log logs/access.log main;
sendfile on;

keepalive_timeout 65;
gzip on;
dyups_upstream_conf vhost/upstream.conf;
include vhost/upstream.conf;
server {
listen 80;
location / {
proxy_pass http://java;
}
}
server {
listen 8081;
location / {
dyups_interface;
}
}
}
在nginx.conf同级目录下创建vhost/upstream.conf文件
upstream java1 {
server 127.0.0.1:7079;
}
upstream java2 {
server 127.0.0.1:7080;
}
upstream java {
server 127.0.0.1:7079;
server 127.0.0.1:7080;
}
启动nginx
./sbin/nginx
配置文件修改后重载
./sbin/nginx -s reload
upstream测试
查看upstream list
curl 127.0.0.1:8081/list
res
java2
java
java1
查看upstream 明细
curl 127.0.0.1:8081/detail
res
java2
server 127.0.0.1:7080
java
server 127.0.0.1:7079
server 127.0.0.1:7080
java1
server 127.0.0.1:8088
修改指定upstream
curl -d "server 127.0.0.1:7079;" 127.0.0.1:8081/upstream/java1
res
success
查看修改后的效果
curl 127.0.0.1:8081/upstream/java1
res
server 127.0.0.1:7079
