gulimall es 集群部署

一.创建docker网络

docker network create --driver bridge --subnet=172.18.12.0/16 --gateway=172.18.1.1 mynet
#查看创建的网络
docker network inspect mynet

二.执行下面进行创建

for port in $(seq 1 3); \
do \
mkdir -p /mydata/elasticsearch/master-${port}/config
mkdir -p /mydata/elasticsearch/master-${port}/data
chmod -R 777 /mydata/elasticsearch/master-${port}
cat << EOF > /mydata/elasticsearch/master-${port}/config/elasticsearch.yml
cluster.name: my-es  #集群的名称，同一个集群该值必须设置成相同的
node.name: es-master-${port}  #该节点的名字
node.master: true  #该节点有机会成为master节点
node.data: false #该节点可以存储数据
network.host: 0.0.0.0
http.host: 0.0.0.0   #所有http均可访问
http.port: 920${port}
transport.tcp.port: 930${port}
discovery.zen.ping_timeout: 10s #设置集群中自动发现其他节点时ping连接的超时时间
discovery.seed_hosts: ["172.18.1.21:9301","172.18.1.22:9302","172.18.1.23:9303"]
cluster.initial_master_nodes: ["172.18.1.21"] #新集群初始时的候选主节点，es7的新增配置
EOF
docker run --name elasticsearch-node-${port} \
-p 920${port}:920${port} -p 930${port}:930${port} \
--network=mynet --ip 172.18.1.2${port} \
-e ES_JAVA_OPTS="-Xms300m -Xmx300m"  \
-v /mydata/elasticsearch/master-${port}/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml  \
-v /mydata/elasticsearch/master-${port}/data:/usr/share/elasticsearch/data  \
-v /mydata/elasticsearch/master-${port}/plugins:/usr/share/elasticsearch/plugins  \
-d elasticsearch:7.4.2
done

for port in $(seq 4 6); \

mkdir -p /mydata/elasticsearch/master-${port}/data

三，可能会出现的问题

出现：error waiting for container: context canceled

#Disable SELinux
sudo setenforce 0

删除docker容器并且删除挂载的目录及文件。

#删除容器
docker rm $(docker ps -a |grep elasticsearch-node-* | awk '{ print $1}')
# 删除挂载的目录
rm -rf /mydata/elasticsearch/

然后重新创建
