搭建环境
ubantu17 `已经安装好docker 17.06.2-ce`
搭建步骤
1. 新建文件es1.yml,es2.yml
/* es1.yml */
network.bind_host: 0.0.0.0
cluster.name: elasticsearch_cluster
node.name: master
node.master: true
node.data: true
http.cors.enabled: true
http.cors.allow-origin: "*"
network.host: 0.0.0.0
discovery.zen.minimum_master_nodes: 1
/* es2.yml */
network.bind_host: 0.0.0.0
cluster.name: elasticsearch_cluster
node.name: node2
node.master: false
node.data: true
http.cors.enabled: true
http.cors.allow-origin: "*"
network.host: 0.0.0.0
discovery.zen.minimum_master_nodes: 1
discovery.zen.ping.unicast.hosts: es1
2. 配置head
一定要在镜像中进行配置如下的两个文件
/usr/src/app/Gruntfile.js
/usr/src/app/_site/app.js
- Gruntfile.js修改以下片段,
connect: {
server: {
options: {
/* 默认监控:127.0.0.1,修改为:0.0.0.0 */
hostname: '0.0.0.0',
port: 9100,
base: '.',
keepalive: true
}
}
- app.js修改以下代码片段:
/* 修改localhost为elasticsearch集群地址,Docker部署中,一般是elasticsearch宿主机地址 */
this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://localhost:9200";
- 为了方便修改将上面的两个文件复制出来挂载在宿主机上,宿主机和容器之间的复制命令为
docker cp host_path containerID:container_path --从主机复制到容器
docker cp containerID:container_path host_path --从容器复制到主机
3. 启动docker-compose up
- 修改虚拟内存
##
cat /etc/sysctl.conf | grep -v "vm.max_map_count" > /tmp/system_sysctl.conf
##
echo "vm.max_map_count=262144" >> /tmp/system_sysctl.conf
##
mv /tmp/system_sysctl.conf /etc/sysctl.conf
- docker-compose文件内容
version: '2.0'

elasticsearch-central:
image: elasticsearch:5.6.4
container_name: es1
volumes:
/* 修改挂载位置 */
- /root/apollo/elasticsearch/data:/usr/share/elasticsearch/data
