本文介绍了Elasticsearch的安装步骤及配置方法，包括下载、解压、内存配置调整、权限设置、网络配置等关键环节。

elasticsearch github 地址为GitHub - elastic/elasticsearch: Free and Open, Distributed, RESTful Search Engine

下载elasticsearch https://www.elastic.co/cn/downloads/past-releases#elasticsearch

注意elasticsearch版本对应的jdk版本。我使用的jdk版本为1.8.0，下载的elasticsearch版本为6.8.8

每一个elasticsearch压缩包中都含有自带的jdk，如果您希望使用最新的elasticsearch版本,最好将java_home设置为elasticsearch自带的jdk目录。一般目录在elasticserach_home/jdk/下

解压elasticsearch

root@ubuntu:/usr/local/elastic# tar -xf elasticsearch-6.8.8.tar.gz

如果您的机器内存有限，启动之前最好先修改 confi目录下jvm.options启动内存

root@ubuntu:/usr/local/elastic/elasticsearch-6.8.8/config# vim jvm.options

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

-Xms512m
-Xmx512m

启动elasticsearch 注意不能使用root用户启动

先将elasticsearch文件目录权限赋予启动用户

root@ubuntu:/usr/local/elastic# chown -R wl:wl /usr/local/elastic/
root@ubuntu:/usr/local/elastic# ll
total 461724
drwxr-xr-x  4 wl   wl        4096 Mar 13 20:31 ./
drwxr-xr-x 26 root root      4096 Mar 13 19:46 ../
drwxr-xr-x  8 wl   wl        4096 Mar 19  2020 elasticsearch-6.8.8/
-rwxrw-rw-  1 wl   wl   149927766 Mar 13 20:07 elasticsearch-6.8.8.tar.gz*
drwxr-xr-x  9 wl   wl        4096 Mar  6 13:58 elasticsearch-7.11.2/
-rwxrw-rw-  1 wl   wl   322857683 Mar 13 19:33 elasticsearch-7.11.2-linux-x86_64.tar.gz*
root@ubuntu:/usr/local/elastic#

启动elasticsearch

wl@ubuntu:/usr/local/elastic/elasticsearch-6.8.8$ bin/elasticsearch

或后台启动

wl@ubuntu:/usr/local/elastic/elasticsearch-6.8.8$ bin/elasticsearch -d

Run curl -X GET http://localhost:9200/ to verify Elasticsearch is running. 如果您没有安装curl可以直接在浏览器输入 http://localhost:9200/ curl安装参考：curl安装

root@ubuntu:/usr/local/elastic# curl -X GET http://localhost:9200/
{
  "name" : "hui1XcR",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "KLSs_y_2QB2wJTmC48b4dQ",
  "version" : {
    "number" : "6.8.8",
    "build_flavor" : "default",
    "build_type" : "tar",
    "build_hash" : "2f4c224",
    "build_date" : "2020-03-18T23:22:18.622755Z",
    "build_snapshot" : false,
    "lucene_version" : "7.7.2",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}
root@ubuntu:/usr/local/elastic#

现在elasticsearch安装完毕。默认配置下，elasticsearch只能本机访问，如果您想别的机器也能访问您的elasticsearch，需要修该以下配置

elasticsearch.yml 增加配置 network.host: 0.0.0.0(注意yaml配置文件格式，冒号后面有个空格)

root@ubuntu:/usr/local/elastic/elasticsearch-6.8.8/config# vim elasticsearch.yml

#network.host: 192.168.0.1
network.host: 0.0.0.0
#

修改 /etc/security/limits.conf 文件如果您在修改上面配置后报错：max file descriptors [4096] for elasticsearch process is too low, increase to at least [65535]


wl               soft    nproc         4097
wl               hard    nproc         4097
wl               soft    nfile          65536
wl               hard    nfile          65536

修改后需要用户退出登陆后再次登陆即执行su wl (上面wl为我的启动elasticservice的用户名称)

使用 ulimit -a 或者 ulimit -Hu 和 ulimit -Hn命令查看

wl@ubuntu:~$ ulimit -a
core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) 15651
max locked memory       (kbytes, -l) 64
max memory size         (kbytes, -m) unlimited
open files                      (-n) 65536
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 0
stack size              (kbytes, -s) 8192
cpu time               (seconds, -t) unlimited
max user processes              (-u) 4097
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited
wl@ubuntu:~$

如果您在配置了/etc/security/limits.conf文件并重新登陆之后却没有修改成功，您需要修改您的sshd_config文件加入下面两个配置

参考

https://manpages.ubuntu.com/manpages/hirsute/en/man5/limits.conf.5.html

https://www.cnblogs.com/zjsylg/p/10470469.html

 UsePAM  yes
 UseLogin yes

注意sshd_config文件的位置。一般默认在/etc/ssh/ 目录下，不过我的目录为/usr/local/etc/。参考我的openssh安装 openssh的安装

wl@ubuntu:/usr/local/etc$ ls
moduli  ssh_config  sshd_config  ssh_host_dsa_key  ssh_host_dsa_key.pub  ssh_host_ecdsa_key  ssh_host_ecdsa_key.pub  ssh_host_ed25519_key  ssh_host_ed25519_key.pub  ssh_host_rsa_key  ssh_host_rsa_key.pub
wl@ubuntu:/usr/local/etc$

修改 /etc/sysctl.conf 如果您在修改上面配置后报错：max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

root@ubuntu:/home/wl# vim /etc/sysctl.conf
#
vm.max_map_count=262144

执行 sysctl -p 使配置生效

root@ubuntu:/home/wl# sysctl -p
vm.max_map_count = 262144

重新启动elasticsearch
