[CentOS7] LEMP Stack – nginx-percona-plugin install
몇일전 고객 요청으로 nginx 위에 cacti 를 설치 했습니다.
1.1.38 Version 의 경우 기본으로 제공되는 템플릿이 없어서 그래프를 그릴수 없습니다.
모니터링시 Authentication Method – > Builtin Authentication 을 None 으로
변경 해야 모든 그래프를 볼수 있습니다.
Percona-plugin 을 사용 하지 않을시 별도의 cacti user 계정은 필요 없습니다.
Nginx 모니터링시 ss_get_by_ssh 스크립트 이용으로 인하여 cacti 또는 별도의 계정이 필요 합니다.
cacti 계정 사용시 필히 /etc/cacti/db.php 권한을 cacti 로 변경 해야 합니다. 변경하지 않았을 경우 cacti 작동이 정상적으로 되지 않습니다.
nginx 설치전 System update 를 진행 합니다.
System update 후 rebooting 을 합니다.
[root@CentOS7 ~]# yum update -y [root@CentOS7 ~]# init 6
- nginx repo file 를 생성 합니다.
[root@CentOS7 ~]# vi /etc/yum.repos.d/nginx.repo [nginx] name=nginx baseurl=http://nginx.org/packages/centos/7/$basearch/ gpgcheck=0 enabled=1 [root@CentOS7 ~]# yum clean all ; yum list

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] y
... Success!
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
