- 配置 Logstash：在
/etc/logstash/conf.d目录下创建远程日志配置文件remote_syslog.conf
input {
syslog {
port => "514"
type => "syslog"

}
filter {}
output {
elasticsearch {
hosts => "localhost:9200"
index => "syslog-%{+YYYY.MM.dd}"

安装 Elasticsearch
- 安装 Elasticsearch
yum --enablerepo=elasticsearch install elasticsearch
- 扩大系统最大文件数：
/etc/security/limits.d/20-nproc.conf
* soft nofile 65536
* hard nofile 131072
* soft nproc 4096
* hard nproc 4096
root soft nproc unlimited
elasticsearch soft memlock unlimited
elasticsearch hard memlock unlimited
- Daemon reload
systemctl daemon-reload
- 配置 MEMLOCK：
/usr/lib/systemd/system/elasticsearch.service
[Service]
LimitMEMLOCK=infinity
- 修改 elasticsearch 配置：
/etc/elasticsearch/elasticsearch.yml
bootstrap.memory_lock: true
http.port: 9200
- 根据系统资源情况修改 heap size：
/etc/elasticsearch/ jvm.options
-Xms4g
-Xmx4g
- 解决虚拟内存太低，增加最大字节处理长度：
/etc/sysctl.conf
vm.max_map_count=655360
# 查看激活
[root@localhost ~]# sysctl -p
vm.overcommit_memory = 1
vm.max_map_count = 655360
