elasticsearch运行

1、报错

OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x0000000085330000, 2060255232, 0) failed; error='Cannot allocate memory' (errno=12) # # There is insufficient memory for the Java Runtime Environment to continue. # Native memory allocation (mmap) failed to map 2060255232 bytes for committing reserved memory. # An error report file with more information is saved as: # /tmp/hs_err_pid1.log

原因是内存不足，修改elasticsearch的配置文件即可

2、解决方法

docker run -itd --privileged -p 9200:9200 -p 9300:9300 --name="es" -e ES_JAVA_OPTS="-Xms256m -Xmx256m" elasticsearch:5.6.12

3、测试

[root@controller ~]# curl 'http://localhost:9200/?pretty' { "name" : "RHezJYn", "cluster_name" : "elasticsearch", "cluster_uuid" : "rXYZfXdkRfG9M_oW2P7FpA", "version" : { "number" : "5.6.12", "build_hash" : "cfe3d9f", "build_date" : "2018-09-10T20:12:43.732Z", "build_snapshot" : false, "lucene_version" : "6.6.1" }, "tagline" : "You Know, for Search" }
