Later, it needs to be added to the systemd method to automatically start at boot.
MySQL deployment
Version 5.7.25 is used here, first download the package
MySQL :: Download MySQL Community Server (Archived Versions)
Go to the server to confirm whether there are residual packages
rpm -qa | grep mysql
yum remove mysql-libs
Install the corresponding rpm package dependencies in order common→libs→client→server.
rpm -ivh mysql-community-common-5.7.25-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.25-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-5.7.25-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-5.7.25-1.el7.x86_64.rpm
Start service
systemctl start mysqld.service
systemctl enable mysqld.service
View initial password
grep 'temporary password' /var/log/mysqld.log
Log in to change password
mysql> set global validate_password_policy=1;
mysql> set password for root@localhost=password('password456');
mysql> grant all privileges on *.* to root@'%' identified by 'password456';
mysql> flush privileges;
prometheus deployment
get package
tar -xvf prometheus-2.32.1.linux-amd64.tar.gz -C /usr/local/
mv prometheus-2.32.1.linux-amd64/ prometheus
Modify configuration file
start up
nohup ./prometheus --enable-feature=remote-write-receiver&
Later, you can set the boot mode to use systemd.
n9e deployment
get package
curl -OL https://github.com/didi/nightingale/releases/download/v5.3.0/n9e-5.3.0.tar.gz
mkdir /usr/local/n9e
tar -xvf n9e-5.3.0.tar.gz -C /usr/local/n9e
Modify the corresponding configuration file
/usr/local/n9e/etc/server.conf
[Redis]
# address, ip:port
Address = "192.168.25.129:6379"
# requirepass
Password = "password456"
[MySQL]
# mysql address host:port
Address = "192.168.25.130:3306"
# mysql username
User = "root"
# mysql password
Password = "password456"
[Reader]
# prometheus base url

# Basic auth username
[[Writers]]
Url = "http://192.168.25.130:9090/api/v1/write"
# Basic auth username

redis mysql
[[Clusters]]
# Prometheus cluster name
Name = "Default"
# Prometheus APIs base url
Prom = "http://192.168.25.130:9090"
Database initialization
mysql -uroot -h192.168.25.130 -ppassword456 < a-n9e.sql
Start the service, and then you can add it to start automatically at boot using systemd.
nohup ./n9e server &
nohup ./n9e webapi &
