一文开源监控软件优秀设备SNMP(开源一文监控软件设备优秀)

写在前面前面简单介绍了该款软件，这篇主要讲安装的过程，大家在使用开源软件的时候不要抱有免费的软件，商业的体验的心态，那是不可能的，该款软件一样存在很多问题，只不过在网络领域还是比其他开源软件要强大不少，至少在易用性、可扩展性还是不错的
正文环境系统版本：CentOS 7.8web：NginxPHP版本：7.3（最低7.3）数据库：Mariadb安装前准备

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-devexit安装、配置DB

yum -y install mariadb-serversystemctl start mariadb && systemctl enable mariadbmysql -uroot -pCREATE 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####修改mariadb配置文件####vi /etc/my.cnfinnodb_file_per_table=1lower_case_table_names=0####wr保存退出####systemctl restart mariadb

添加配置PHP-FPM配置1.修改时区vi /etc/php.ini修改时区2.修改php-fpm配置文件

vi /etc/php-fpm.d/www.conf####改为如下####;user = apacheuser = nginxgroup = apache;listen = 127.0.0.1:9000listen = /run/php-fpm/php-fpm.socklisten.owner = nginxlisten.group = nginxlisten.mode = 0660

3.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Nginxsystemctl enable nginxsystemctl restart nginxSNMP配置

cp /opt/librenms/snmpd.conf.example /etc/snmp/snmpd.confycurl -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
