docker compose部署opensearch集群

docker compose 配置

假设有两台电脑
A电脑的ip为192.168.1.100
B电脑的ip为192.168.1.103
A电脑的docker compose 配置

设置内存

临时

sysctl -w vm.max_map_count=262144

永久

Disable memory paging and swapping performance on the host to improve performance.
禁用主机上的内存分页和交换性能以提高性能。
ps：这个看情况，内存大的话，也可以关掉

sudo swapoff -a

Increase the number of memory maps available to OpenSearch.
增加OpenSearch可用的内存映射数量。

# Edit the sysctl config file
sudo vi /etc/sysctl.conf# Add a line to define the desired value
# or change the value if the key exists,
# and then save your changes.
vm.max_map_count=262144# Reload the kernel parameters using sysctl
sudo sysctl -p# Verify that the change was applied by checking the value
cat /proc/sys/vm/max_map_count

两边同时启动

docker compose up -d
