[root@vm-centos75-0-69 opt]# mkdir -p cosmo/logs
二、配置prometheus
2.1 解压
##### 进入安装包存放目录
[root@vm-centos75-0-69 ~]# cd /opt/cosmo/tools
##### 解压
[root@vm-centos75-0-69 packages]# tar -Pxvf prometheus-2.8.1.linux-amd64.tar.gz
2.2 启动
##### 进入prometheus目录
[root@vm-centos75-0-69 ~]# cd /opt/cosmo/com/prometheus-2.8.1.linux-amd64
##### 使用nohup后台启动命令 --web.enable-lifecycle 是启动运行时重新加载其配置的 配置项：
[root@vm-centos75-0-69 prometheus-2.8.1.linux-amd64]# nohup ./prometheus --web.enable-lifecycle >> /opt/cosmo/logs/prometheus.out 2>&1 &
重新加载配置的启动方式
# prometheus 重新加载配置的命令：curl -X POST http://192.168.0.69:9090/-/reload
2.3 关闭
# 查看prometheus服务状态
[root@vm-centos75-0-69 ~]# ps -ef | grep prometheus
root 2966 1 0 5月23 ? 00:09:40 ./prometheus
root 6325 6300 0 15:20 pts/0 00:00:00 grep --color=auto prometheus
# 关闭prometheus服务
[root@vm-centos75-0-69 ~]# pkill prometheus
2.4 其他配置
# 进入prometheus目录
[root@vm-centos75-0-69 ~]# cd /opt/prometheus-2.8.1.linux-amd64
# 查看prometheus文件
[root@vm-centos75-0-69 prometheus-2.8.1.linux-amd64]# ll

把03_配置文件中的prometheus文件夹中的prometheus.yml 修正后 上传文件替换掉原本的prometheus.yml
把03_配置文件中的prometheus文件夹中的file_sd_configs 放到prometheus-2.8.1.linux-amd64下
然后执行curl -X POST http://192.168.0.69:9090/-/reload
下面是自身环境的prometheus.yml配置文件,
根据现场的实际情况修改- job_name: 'prometheus' 下的 static_configs: 中的 - targets: [IP+端口]
- job_name: 'redis_exporter' 下的 relabel_configs: 中的 -replacement: [IP+端口]
全局配置节点下的配置对所有其它节点都有效，同时也是其它节点的默认值

三、配置grafana
3.1 解压
- 进入安装包存放目录
[root@vm-centos75-0-69 ~]# cd /opt/cosmo/tools
- 解压
[root@vm-centos75-0-69 tools]# tar -Pxvf grafana-6.2.0.linux-amd64.tar.gz
3.2 启动
- 进入grafana下的bin目录
[root@vm-centos75-0-69 ~]# cd /opt/cosmo/com/grafana-6.2.0/bin
# 使用nohup后台启动命令：
[root@vm-centos75-0-69 bin]# nohup ./grafana-server >> /opt/cosmo/logs/grafana.out 2>&1 &
3.3 关闭
- 查看grafana服务状态
[root@vm-centos75-0-69 ~]# ps -ef | grep grafana-server
root 6381 6300 4 15:55 pts/0 00:00:00 ./grafana-server
root 6394 6300 0 15:55 pts/0 00:00:00 grep --color=auto grafana-server
- 关闭grafana服务
[root@vm-centos75-0-69 ~]# pkill grafana-server
3.4 其他配置
- 进入grafana目录
[root@vm-centos75-0-69 ~]# cd /opt/cosmo/com/grafana-6.2.0

drwxr-xr-x 5 root root 60 5月 22 19:29 provisioning
-rw-r--r-- 1 root root 16841 5月 22 19:19 sample.ini
修改defaults.ini文件
然后重启grafana服务
因为defaults.ini文件过长，所以只选取需要修改的部分进行展示
根据实际的现场环境开放的端口号，修改http_port，默认端口为5020
#################################### Server ##############################
[server]
# Protocol (http, https, socket)
protocol = http
# The ip address to bind to, empty will bind to all interfaces
http_addr =
# The http port to use
http_port = 5020
# The public facing domain name used to access grafana from a browser
domain = localhost
# Redirect to correct domain if host header does not match domain
# Prevents DNS rebinding attacks
enforce_domain = false
# The full public facing url
root_url = %(protocol)s://%(domain)s:%(http_port)s/
# Log web requests
router_logging = false
# the path relative working path
static_root_path = public
# enable gzip
enable_gzip = false
# https certs & key file
cert_file =
cert_key =
# Unix socket path
socket = /tmp/grafana.sock
# 修改 security下的 allow_embedding修改为true
# 当false，HTTP报头X-Frame-Options: deny将在Grafana HTTP响应被设置，这将指示浏览器不允许在一个渲染Grafana <frame>，<iframe>，<embed>或<object>。主要目标是降低Clickjacking的风险。默认是false。
#################################### Security ############################
[security]
# default admin user, created on startup
admin_user = admin
# default admin password, can be changed before first start of grafana, or in profile settings
admin_password = admin
# used for signing
secret_key = SW2YcwTIb9zpOOhoPsMm
# disable gravatar profile images
disable_gravatar = false
# data source proxy whitelist (ip_or_domain:port separated by spaces)
data_source_proxy_whitelist =
# disable protection against brute force login attempts
disable_brute_force_login_protection = false
# set to true if you host Grafana behind HTTPS. default is false.
cookie_secure = false
# set cookie SameSite attribute. defaults to `lax`. can be set to "lax", "strict" and "none"
cookie_samesite = lax
# set to true if you want to allow browsers to render Grafana in a <frame>, <iframe>, <embed> or <object>. default is false.
# 默认false,需要修改成true
allow_embedding = true
# 修改auth.anonymous下的enabled 为true，
# 因为enabled默认是不开启匿名访问的，需要开启匿名访问
#################################### Anonymous Auth ######################
[auth.anonymous]
# enable anonymous access
# 默认值为false 需要修改成true
enabled = true
# specify organization name that should be used for unauthenticated users
org_name = Main Org.
# specify role for unauthenticated users
org_role = Viewer
四、配置node_exporter
4.1 解压
# 进入安装包存放目录
[root@vm-centos75-0-69 ~]# cd /opt/cosmo/tools
# 解压
[root@vm-centos75-0-69 tools]# tar -Pxvf node_exporter-0.17.0.linux-amd64.tar.gz
4.2 启动
# 进入node_exporter安装目录
[root@vm-centos75-0-69 ~]# cd /opt/cosmo/com/node_exporter-0.17.0.linux-amd64
# 启动node_exporter服务
[root@vm-centos75-0-69 node_exporter-0.17.0.linux-amd64]# nohup ./node_exporter --web.listen-address=":5021" >> /opt/cosmo/logs/nodeExporter.out 2>&1 &
4.3 关闭
# 查询node_exporter服务
[root@vm-centos75-0-69 ~]# ps -ef | grep node_exporter
root 1921 1 0 5月23 ? 00:09:59 /opt/node_exporter-0.17.0/node_exporter --web.listen-address=:5021
root 6556 6300 0 18:02 pts/0 00:00:00 grep --color=auto node_exporter
# 删除node_exporter进程
[root@vm-centos75-0-69 ~]# pkill node_exporter
五、配置jmx_exporter
5.1 集成
# 把cosmo_jmx_prometheus.jar和tomcat.yml放入需要监控的tomcat中的lib文件夹下。
# 更改tomcat的bin文件夹下的catalina.sh文件
# 找到
JAVA_OPTS="$JAVA_OPTS -Djava.protocol.handler.pkgs=org.apache.catalina.webresources"
# 在上段代码后，把下段代码粘在下面
JAVA_OPTS="$JAVA_OPTS -javaagent:$CATALINA_HOME/lib/cosmo_jmx_prometheus.jar=5915:$CATALINA_HOME/lib/tomcat.yml"
# 注意上面的端口号：5915
# 如果当前启动服务的端口为5910则监听端口为5915
# 如果当前启动服务的端口为5920则监听端口为5925
# 依此类推
# 然后重启tomcat
六、配置mysqld_exporter
6.1 解压
# 进入安装包存放目录
[root@vm-centos75-0-69 ~]# cd /opt/cosmo/tools
# 解压
[root@vm-centos75-0-69 tools]# tar -Pxvf mysqld_exporter-0.12.1.linux-amd64.tar.gz
6.2 配置、启动

# 创建.my.cnf文件,填入信息
# host --- mysql数据库所在服务器ip
# user --- mysql数据库用户名
# password --- mysql数据库密码
# port --- mysql数据库端口
[client]
host=192.168.0.133
user=root
password=root
port=3306
# 如果权限分权明确，则只给查询权限的用户就可，否则不用理会创建用户
# mysqld_exporter需要连接到Mysql，所以需要Mysql的权限，
# 我们这里可以使用root用户(也可以授权新用户)
# CREATE USER 'mysqlexporter'@'localhost' IDENTIFIED BY 'msyqlexporter';
# GRANT PROCESS, REPLICATION CLIENT, SELECT ON *.* TO 'exporter'@'localhost';
# 启动mysqld_exporter服务
[root@vm-centos75-0-69 mysqld_exporter-0.12.1.linux-amd64]# nohup ./mysqld_exporter --config.my-cnf=.my.cnf >> /opt/cosmo/logs/mysqlExporter.out 2>&1 &
6.3 关闭
# 查询mysqld_exporter服务
[root@vm-centos75-0-69 ~]# ps -ef | grep mysqld_exporter
root 2661 19011 0 14:39 pts/0 00:00:00 grep --color=auto mysqld_exporter
root 26077 19011 0 11:35 pts/0 00:00:41 ./mysqld_exporter --config.my-cnf=.my.cnf
# 删除mysqld_exporter进程
[root@vm-centos75-0-69 ~]# pkill mysqld_exporter
七、配置redis_exporter

# 进入存放目录
[root@vm-centos75-0-69 ~]# cd /opt/cosmo/tools
# 解压
[root@vm-centos75-0-69 packages]# tar -Pxvf redis_exporter.tar.gz
7.2 启动
# 进入redis_exporter安装目录
[root@vm-centos75-0-69 ~]# cd /opt/cosmo/com/
# 启动redis_exporter服务 -- 针对的是redis统一一个密码，如果每个redis的密码不同，则需要创建多个redis_exporter
# --redis.password= redis的密码， 注意更改
[root@vm-centos75-0-69 com]# nohup ./redis_exporter --redis.password=cosmo_redis_74 >> /opt/cosmo/logs/redis_exporter.out 2>&1 &
7.3 关闭
# 查询redis_exporter服务
[root@vm-centos75-0-69 ~]# ps -ef|grep redis_exporter
root 12375 19011 0 17:52 pts/0 00:00:00 ./redis_exporter
root 12884 19011 0 18:01 pts/0 00:00:00 grep --color=auto redis_exporter

九、配置nginx_vts_exporter
9.1 解压
nginx-module-vts：Nginx的监控模块，能够提供JSON格式的数据产出。 nginx-vts-exporter：主要用于收集Nginx的监控数据，并给Prometheus提供监控接口，默认端口号9913。
# 进入存放目录
[root@vm-centos75-0-69 ~]# cd /opt/cosmo/tools/
# 解压nginx-module-vts模块
[root@vm-centos75-0-69 tools]# tar -Pxvf nginx-module-vts-0.1.18.tar.gz
# 解压nginx-vts-exporter
[root@vm-centos75-0-69 tools]# tar -Pxvf nginx-vts-exporter-0.10.3.linux-amd64.tar.gz
9.2 编译配置
（在安装nginx的服务器上添加nginx-module-vts）
# 进入nginx-1.16.1存放目录
[root@vm-centos75-0-69 ~]# cd /usr/local/nginx-1.16.1/
# 在nginx 编译时添加vts模块--add-module=/usr/local/nginx-module-vts-0.1.18
[root@vm-centos75-0-69 nginx-1.16.1]# ./configure --add-module=/usr/local/nginx-module-vts-0.1.18 && make && make install
注：
如果报找不到C编译器，需要下载gcc等依赖（在线或离线下载依赖）
以下是离线下载,安装文件夹是rpm文件夹下的所有.rpm文件
[root@vm-centos75-0-69 rpm]# rpm -ivh *.rpm --nodeps --force
# 进入nginx.conf存放目录
[root@vm-centos75-0-69 ~]# cd /usr/local/nginx/conf/
nginx.conf配置添加
添加成功后--->（监控数据的查看地址http://192.168.0.71:8088/status）
vhost_traffic_status_zone;
vhost_traffic_status_filter_by_host on;
server {
listen 8088;
location /status {
vhost_traffic_status_display;
vhost_traffic_status_display_format html;
}
}
9.3 启动
# 进入nginx-vts-exporter存放目录
[root@vm-centos75-0-69 /]# cd /opt/cosmo/com/nginx-vts-exporter-0.10.3.linux-amd64/
# 授权
[root@vm-centos75-0-69 nginx-vts-exporter-0.10.3.linux-amd64]# chmod +x nginx-vts-exporter
# 启动nginx-vts-exporter服务
[root@vm-centos75-0-69 nginx-vts-exporter-0.10.3.linux-amd64]# nohup ./nginx-vts-exporter -nginx.scrape_uri=http://192.168.0.71:8088/status/format/json >> /opt/cosmo/logs/nginx_vts_exporter.out 2>&1 &
9.4 关闭
# 查询nginx-vts-exporter服务
[root@vm-centos75-0-71 nginx-vts-exporter-0.10.3.linux-amd64]# ps -ef|grep nginx-vts-exporter
root 19247 7164 0 16:12 pts/0 00:00:01 ./nginx-vts-exporter -nginx.scrape_uri=http://192.168.0.71:8088/status/format/json
root 22758 7164 0 17:22 pts/0 00:00:00 grep --color=auto nginx-vts-exporter
# 删除nginx-vts-exporter进程
[root@vm-centos75-0-71 ~]# pkill nginx-vts-exporter
