部署步骤
docker安装部署
#更新yum源（一下均为root用户）
yum update
#安装docker
yum remove docker-ce -y && yum install docker-ce -y && service docker start
#docker启动
systemctl start docker
#docker设置开机启动
systemctl enable docker
#docker停止
systemctl stop docker
#有时候需要使用这种命令启动
systemctl start docker.service
systemctl enable docker.servicedocker镜像配置
在宿主机器编辑文件：vim /etc/docker/daemon.json#请在该配置文件中加入（没有该文件的话，请先建一个）：
{
"registry-mirrors": ["https://docker.mirrors.ustc.edu.cn"]
}Elasticsearch安装部署
拉取指定版本镜像
#拉取镜像 docker pull elasticsearch:7.7.0从官网拉取最新（目前最新是7.16.0）
docker pull docker.elastic.co/elasticsearch/elasticsearch:7.16.0
docker images 命令查看镜像列表docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
elasticsearch 7.7.0 7ec4f35ab452 15 months ago 757MB

调高JVM线程数限制数量
vim /etc/sysctl.conf ->> vm.max_map_count=262144刷新配置
sysctl -p

ES负载均衡
nginx配置es负载均衡修改nginx配置文件
#修改nginx配置文件
vim /home/jamelli/software/nginx/conf.d/default.conf
->>
upstream es{
least_conn; #把请求转发给连接数较少的后端服务器
server 192.168.1.127:9201;#ES对应的ip:port
server 192.168.1.127:9202;
server 192.168.1.127:9203;
}
server {
listen 9210;
server_name localhost;
underscores_in_headers on;
location / {
proxy_set_header Host $host:$server_port;
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://es;
}
}
# 重新加载nginx使生效(二选一)
docker restart nginx
nginx -s reload
此刻访问服务器的9210端口会负载均衡到es集群上，测试一下。看下图可以看到已经可以轮询es了
