CentOS 7 安装 cacti 1.1.x

由于cacti 1.1.x系列发布后，变化比较大，集成了很多插件，自带自动发现功能，所以记录下来，@H_197_15@

@H_197_15@

1、安装mariadb 10.1@H_197_15@

cacti 1.1.0 需要MysqL >= 5.6,所以这里选择mariadb 10.1@H_197_15@

yuminstallcentos-release-openstack-ocata-y
yuminstallmariadb-server-y
systemctlenablemariadb
systemctlstartmariadb

@H_197_15@

2、mariadb参数调整（最低要求）@H_197_15@ @H_61_30@max_heap_table_size=128M max_allowed_packet=32M tmp_table_size=64M join_buffer_size=64M innodb_buffer_pool_size=512M innodb_doublewrite=off innodb_flush_log_at_timeout=3

导入时区信息@H_197_15@

@H_197_15@

MysqL_tzinfo_to_sql/usr/share/zoneinfo/|MysqL-uroot-pMysqL

@H_197_15@

3、安装lamp@H_197_15@

yuminstallhttpdPHPPHP-MysqLndPHP-gdPHP-snmpPHP-pecl-zendopcachewget-y

4、下载cacti@H_197_15@

cd/var/wwww/html
wgethttp://www.cacti.net/downloads/cacti-1.1.0.tar.gz
tarzxvfcacti-1.1.0.tar.gz
mvcacti-1.1.0cacti

chown-Rapache:apache/var/www/html/cacti/cache/spikekill

@H_197_15@

5、给cacti建库@H_197_15@

MysqL>createdatabasecactidefaultcharsetutf8mb4;
MysqL>usecacti;
MysqL>source/var/www/html/cacti/cacti.sql;
MysqL>grantalloncacti.*to'cactiuser'@'localhost'identifiedby'cactiuser';
MysqL>grantSELEctonMysqL.time_zone_nametocactiuser@'localhost';
MysqL>flushprivileges;

@H_197_15@

6、访问http://ip/cacti 进入安装向导@H_197_15@

@H_197_15@

7、默认用户密码admin/admin，首次登陆要求改密码，密码长度和复杂度都比较严格，点赞。@H_197_15@

@H_197_15@

8、自动发现的功能有点类似zabbix@H_197_15@

a、定义snmp选项，比如snmpv2，community为abc
b、定义扫描网段，比如192.168.0.0/24，定时扫描，发现snmp端口存活的机器自动添加到cacti，
c、定义规则，将扫描到的机器，按照操作系统分类，放入不同的tree，划不同的图

@H_197_15@

9、设置定时任务@H_197_15@

*/5****apache/usr/bin/PHP-q/usr/share/cacti/poller.PHP>/dev/null

@H_197_15@

@H_197_15@

cacti 1.1.x 支持中文，但是汉化不彻底，手痒的同学可以按照下面的办法汉化：@H_197_15@

1、安装@H_197_15@

@H_197_15@

2、反编译mo文件为po文件@H_197_15@

cd/var/www/html/cacti/locales/LC_messaGES

@H_197_15@

3、用文本编辑器修改文件@H_197_15@

@H_197_15@
