1.环境准备
confd需要和nginx安装在同一台服务器上
主机名 | IP地址 | CPU | 内存 | 硬盘 |
gztxy-prd-nginx01 | 192.168.1.21 | 4 | 8 | 100GB |
gztxy-prd-nginx01 | 192.168.1.31 | 4 | 8 | 100GB |
2.安装并配置
安装
#下载confd wget https://github.com/kelseyhightower/confd/releases/download/v0.16.0/confd-0.16.0-linux-amd64 mv confd-0.16.0-linux-amd64 /usr/bin/confd chmod +x /usr/bin/confd #检测是否安装成功 confd --version confd 0.16.0 (Git SHA: 7217b0ca, Go Version: go1.10.2) #confd的配置文件,主要包含配置的生成逻辑,例如模板源,后端存储对应的keys,命令执行等。 #templates:配置模板Template,即基于不同组件的配置,修改为go语言的模板文件 mkdir -p /etc/confd/{conf.d,templates} #nginx需配置check_status后端检测(模块的编译以及配置已经在nginx初始化脚本里,按道理是应该是妥妥的) #获取方式为http://IP/view/?format=json location /view { check_status; access_log off; } #启动confd,每隔5秒轮询一次,并根据CMDB的etcd传入的json数组动态生成配置文件 nohup confd -interval=5 -backend etcd -node http://192.168.1.11:2379 -node http://192.168.1.12:2379 -node http://192.168.1.13:2379 >> /data/confd.log &
配置
在Nginx网关里,配置Confd的2个配置文件
新增 Keys,不能重复,增加注意文件格式
cat > /etc/confd/conf.d/behavior-nginx.toml <<EOF [template] src = "nginx.tmpl" dest = "/usr/local/nginx/conf/vhost/up.conf" owner = "root" keys = [ "/behavior", "/kuasheng-gzzs" ] reload_cmd = "/usr/local/nginx/sbin/nginx -s reload" EOF #cat /etc/confd/templates/nginx.tmpl #增加完Key后,修改UPstream的配置模板,复制存在的UPstream,修改对应的UPstream名字即可,其它保持一样 cat > /etc/confd/templates/nginx.tmpl <<EOF upstream behavior{ {{range jsonArray (getv "/behavior")}} server {{ .}} max_fails=2 fail_timeout=40s weight=10; {{end}} check_http_send "HEAD /info HTTP/1.0 "; check interval=3000 rise=2 fall=5 timeout=1000 type=http; } upstream kuasheng-gzzs{ {{range jsonArray (getv "/kuasheng-gzzs")}} server {{ .}} max_fails=2 fail_timeout=40s weight=10; {{end}} check_http_send "HEAD /interiorappapi/actuator/info HTTP/1.0 "; check interval=3000 rise=2 fall=5 timeout=1000 type=http; } EOF
配置nginx
cat > /usr/local/nginx/conf/vhost/up.conf <<EOF server { listen 80; server_name localhost; location /view { check_status; access_log off; } location /api/kuasheng/behavior { proxy_pass http://behavior/; } location /interiorappapi/ { proxy_pass http://kuasheng-gzzs; } error_page 502 /502.json; location /502.json { } error_page 404 /404.json; location /404.json { } } EOF
3.测试
#添加behavior和kuasheng-gzzs值
etcdctl -C http://192.168.1.11:2379 set /behavior "["192.168.1.11:10900", "192.168.1.12:10900"]"
etcdctl -C http://192.168.1.11:2379 set /kuasheng-gzzs "["192.168.1.11:80", "192.168.1.12:80"]"
#自动生成 /usr/local/nginx/conf/vhost/up.conf文件
upstream behavior{
server 192.168.1.11:10900 max_fails=2 fail_timeout=40s weight=10;
server 192.168.1.20:10900 max_fails=2 fail_timeout=40s weight=10;
check_http_send "HEAD /info HTTP/1.0
";
check interval=3000 rise=2 fall=5 timeout=1000 type=http;
}
upstream kuasheng-gzzs{
server 192.168.1.11:10900 max_fails=2 fail_timeout=40s weight=10;
server 192.168.1.20:10900 max_fails=2 fail_timeout=40s weight=10;
check_http_send "HEAD /interiorappapi/actuator/info HTTP/1.0
";
check interval=3000 rise=2 fall=5 timeout=1000 type=http;
}
