安装前准备
- yum install epel-release yum-utils -y
- yum localinstall http://rpms.remirepo.net/enterprise/remi-release-7.rpm -y
- yum-config-manager --enable remi-php74
- yum install composer cronie fping git ImageMagick jwhois mariadb mariadb-server mtr MySQL-python net-snmp net-snmp-utils nginx nmap php-fpm php-cli php-common php-curl php-gd php-mbstring php-process php-snmp php-xml php-zip php-memcached php-mysqlnd python-memcached rrdtool python3 python3-pip -y
创建LibreNMS用户
- useradd librenms -d /opt/librenms -M -r
- usermod -a -G librenms nginx
下载LibreNMS文件
- cd /opt
- git clone https://github.com/librenms/librenms.git
如果大家出现这个问题，将上文地址由https改为git，但是非常慢
设置权限
- chown -R librenms:librenms /opt/librenms
- chmod 770 /opt/librenms
- setfacl -d -m g::rwx /opt/librenms/rrd /opt/librenms/logs /opt/librenms/bootstrap/cache/ /opt/librenms/storage/
- setfacl -R -m g::rwx /opt/librenms/rrd /opt/librenms/logs /opt/librenms/bootstrap/cache/ /opt/librenms/storage/
- chgrp apache /var/lib/php/session/
安装PHP依赖组件
- su - librenms
- ./scripts/composer_wrapper.php install --no-dev
- exit
安装、配置DB
- yum -y install mariadb-server
- systemctl start mariadb && systemctl enable mariadb
- mysql -uroot -p
- CREATE DATABASE librenms CHARACTER SET utf8 COLLATE utf8_unicode_ci;
- CREATE USER 'librenms'@'localhost' IDENTIFIED BY 'xiaoyu123';
- GRANT ALL PRIVILEGES ON librenms.* TO 'librenms'@'localhost';
- FLUSH PRIVILEGES;
- quit

添加配置
PHP-FPM配置
修改时区
- vi /etc/php.ini
修改时区
修改php-fpm配置文件
- vi /etc/php-fpm.d/www.conf
- ####改为如下####
- ;user = apache
- user = nginx
- group = apache
- ;listen = 127.0.0.1:9000
- listen = /run/php-fpm/php-fpm.sock
- listen.owner = nginx
- listen.group = nginx
- listen.mode = 0660
重启php-fpm服务
- systemctl enable php-fpm
- systemctl restart php-fpm
配置Nginx
- vi /etc/nginx/conf.d/librenms.conf
- ####添加如下内容####
- server {
- listen 80;
- server_name librenms.example.com;
- root /opt/librenms/html;
- index index.php;
-
- charset utf-8;
- gzip on;
- gzip_types text/css application/javascript text/javascript application/x-javascript image/svg+xml text/plain text/xsd text/xsl text/xml image/x-icon;
- location / {
- try_files $uri $uri/ /index.php?$query_string;
- }
- location /api/v0 {
- try_files $uri $uri/ /api_v0.php?$query_string;
- }
- location ~ \.php {
- include fastcgi.conf;
- fastcgi_split_path_info ^(.+\.php)(/.+)$;
- fastcgi_pass unix:/run/php-fpm/php-fpm.sock;
- }
- location ~ /\.ht {
- deny all;
- }
- }
启动Nginx
- systemctl enable nginx
- systemctl restart nginx
SNMP配置
- cp /opt/librenms/snmpd.conf.example /etc/snmp/snmpd.conf
- y
- curl -o /usr/bin/distro https://raw.githubusercontent.com/librenms/librenms-agent/master/snmp/distro
- chmod +x /usr/bin/distro
- systemctl enable snmpd &&systemctl restart snmpd
计划任务
- cp /opt/librenms/librenms.nonroot.cron /etc/cron.d/librenms
复制LibreNMS配置文件
- cp /opt/librenms/misc/librenms.logrotate /etc/logrotate.d/librenms
访问前端
此时会发现访问还是Nginx的界面，这里需要调整一些参数
- vi /etc/nginx/nginx.conf
- systemctl restart nginx
将端口改为8080
前端配置
点击图标进行下一步
检查通过
填写数据库信息
通过之后点击build
点击红框才能下一步
正常是空的dashboard
设置中文
简单使用
新增设备
最终效果
总结
该软件部署较为复杂，如果仅仅想体验可以试试容器版本，目前官方提供apache和nginx两种版本，容器版本使用起来设备如果不多还是可以的，当然如果有一定基础的可以自行安装，但该软件的特点主要使用简单，监控项细致，但目前该软件还是存在一定的问题，例如华为WLAN部分access user显示有一定问题，预测是后台的mib逻辑调用存在异常导致，另外负载也有相对应的问题，所以大家如果想用，不妨先测试，最终决定是否使用。
