tar -zxvf elasticsearch-7.3.1-linux-x86_64.tar.gz在es下创建数据和日志文件夹，修改配置文件
#对应配置里的数据和日志文件目录 mkdir /usr/local/src/elasticsearch/elasticsearch-7.3.1/data mkdir /usr/local/src/elasticsearch/elasticsearch-7.3.1/logs vim config/elasticsearch.ymlcluster.name: my-application
node.name: node-10
path.data: /usr/local/src/elasticsearch/elasticsearch-7.3.1/data
path.logs: /usr/local/src/elasticsearch/elasticsearch-7.3.1/logs
新建elkuser用户(注意不能使用root用户启动es)
#创建用户 useradd elkuser #修改用户组和用户 chown -R elkuser:elkuser elasticsearch-7.3.1 #切换用户 su elkuser启动

Nginx
安装PCRE
安装编译工具及库文件
yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel首先要安装 PCRE(作用是让 Nginx 支持 Rewrite 功能)
#下载 wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz #解压安装包 tar -zxvf pcre-8.35.tar.gz #进入安装包目录 cd pcre-8.35 #编译安装 ./configure make && make install #查看pcre版本 pcre-config --version
安装Nginx
#下载 wget http://nginx.org/download/nginx-1.6.2.tar.gz #解压安装包 tar -zxvf nginx-1.6.2.tar.gz #进入安装包目录 cd nginx-1.6.2/ #编译安装(注意pcre路径) ./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/nginx/pcre-8.35 make && make install #查看pcre版本 /usr/local/webserver/nginx/sbin/nginx -v
检查
#检查配置文件nginx.conf的正确性命令 /usr/local/webserver/nginx/sbin/nginx -t
启动 Nginx
/usr/local/webserver/nginx/sbin/nginx #查看进程 ps -ef |grep nginx
Nginx 其他命令
/usr/local/webserver/nginx/sbin/nginx -s reload # 重新载入配置文件 /usr/local/webserver/nginx/sbin/nginx -s reopen # 重启 Nginx /usr/local/webserver/nginx/sbin/nginx -s stop # 停止 Nginx浏览器访问站点

kibana
下载解压
tar -zxvf kibana-7.3.1-linux-x86_64.tar.gz #进入kibana配置下 cd kibana-7.3.1-linux-x86_64/config #修改配置文件 vim kibana.ymlserver.host: "localhost"
elasticsearch.hosts: ["http://localhost:9200"]
启动(kibana不建议以root用户启动，如果用root启动，需要加--allow-root)
