安裝jdk

 

安裝elasticsearch

unzip elasticsearch-5.1.1.zip

[tommy@localhost ~]$ unzip elasticsearch-5.1.1.zip

 

配置

$ vi config/elasticsearch.yml

[tommy@localhost elasticsearch-5.1.1]$ vi config/elasticsearch.yml

打開network.host設置爲當前ip

# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
network.host: 192.168.1.107
#
# Set a custom port for HTTP:
#
http.port: 9200
#
# For more information, see the documentation at:
# <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html>
#

 

啓動

cd elasticsearch-5.1.1/bin/

./elasticsearch

[tommy@localhost ~]$ cd elasticsearch-5.1.1/bin/
[tommy@localhost bin]$ ./elasticsearch

遇到以下錯誤

設置 max file descriptors （linux可以打開的最大文件句柄數）

在 /etc/security/limits.conf 文件最後添加

* hard nofile 65536
* soft nofile 65536

[root@localhost home]# echo '* hard nofile 65536' >> /etc/security/limits.conf 
[root@localhost home]# echo '* soft nofile 65536' >> /etc/security/limits.conf

注意是 >>  千萬不要少打一個 > 

設置 max number of threads （linux容許每一個用戶的最大線程數）

修改 vi /etc/security/limits.d/90-nproc.conf

# Default limit for number of user's processes to prevent
# accidental fork bombs.
# See rhbz #432903 for reasoning.

*          soft    nproc     2048
root       soft    nproc     unlimited

設置 vm.max_map_count （限制一個進程能夠擁有的VMA(虛擬內存區域)的數量）

echo 262144 > /proc/sys/vm/max_map_count

sysctl -p

[root@localhost home]# echo 262144 > /proc/sys/vm/max_map_count

退出再次ssh到服務器啓動elasticsearch

遇到以下錯誤

[tommy@localhost bin]$ ./elasticsearch

# An error report file with more information is saved as:

設置elasticsearch jvm配置

vi config/jvm.options （調整jvm參數）

################################################################

# Xms represents the initial size of total heap space
# Xmx represents the maximum size of total heap space

-Xms1g
-Xmx1g

 

Caused by: java.lang.IllegalStateException: failed to obtain node locks, tried [[/home/tommy/elasticsearch-5.1.1/data/my-application]] with lock id [0]; maybe these locations are not writable or multiple nodes were started without increasing [node.max_local_storage_nodes] (was [1])?

在 elasticsearch-5.1.1/data/nodes/0 目錄下有一個 node.lock

rm -rf node.lock 便可 

 

以守護模式啓動

$ bin/elasticsearch -d

./bin/elasticsearch -d -p pid

查看日誌

tail -100f logs/xxx.log （節點名）

[tommy@localhost elasticsearch-5.1.1]$ tail -100f logs/elasticsearch.log

殺死進程

kill `cat pid`
