CentOS 8/oracle linux 8 安装和配置Cacti

1、yum 安装cacti

#yum install cacti

2、安装mariadb-server

#yum install mariadb-server

3、oracle linux 8 还需单独安装php-fpm

#yum install php-fpm

4、相关配置

a. 配置maraidb

#mysql_secure_installation  //设置root密码

#mysql -u root -p  //创建cacti数据库和用户、密码

CREATE DATABASE cacti;

GRANT ALL ON cacti.* TO 'cacti'@'localhost' IDENTIFIED BY 'StrongDBPassword';

FLUSH PRIVILEGES;

exit

#vi  /etc/muy.cnf.d/mariadb-server.cnf

[mariadb-10.3]

collation-server=utf8mb4_unicode_ci

character-set-server=utf8mb4

max_heap_table_size=250M

tmp_table_size=250M

join_buffer_size=500M

innodb_buffer_pool_size=3876M

innodb_flush_log_at_timeout=3

innodb_read_io_threads=32

innodb_write_io_threads=16

innodb_buffer_pool_instances=33

innodb_io_capacity=5000

innodb_io_capacity_max=10000

innodb_file_format=Barracude

innodb_large_prefix=1

#mysql -u root -p cacti  < /usr/share/doc/cacti/cacti.sql  //初始化cacti数据库

#mysql_tzinfo_to_sql /usr/share/zoneinfo |mysql -u root -p mysql   //装入timezone数据

#mysql -u root -p

GRANT SELECT ON mysql.time_zone_name TO cacti@localhost;

ALTER DATABASE cacti CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

FLUSH PRIVILEGES;

quit

#systemctl enable --now mariadb

b.配置php

#vi /etc/php.ini

; http://php.net/date.timezone

date.timezone = Asia/Shanghai  //设置timezone

memory_limit = 400M  //将PHP内存限制更改为400M

#systemctl enable --now php-fpm

c.配置httpd

#systemctl enable --now httpd

d.配置cacti

#vi /etc/httpd/conf.d/cacti.conf

       

           #httpd 2.4

           #Require host localhost

           Require all granted     #change

      

...

#vi /usr/share/cacti/include/config.php

$database_type     = 'mysql';

$database_default  = 'cacti';

$database_hostname = 'localhost';

$database_username = 'cacti';

$database_password = 'StrongDBPassword';

$database_port     = '3306';

#crontab -u apache -e //设置定时数据采集

*/5 * * * * php /usr/share/cacti/poller.php > /dev/null 2>&1

e.安全设置

#setenforce 0

#vi /etc/sysconfig/selinux

SELINUX=disabled

#firewall-cmd --add-service={http,https} --permanent

#firewall-cmd --reload

5、运行cacti向导

http://ip/cacti

用户名密码admin/admin

修改密码

如果有警告或错误，按提示修改

 6.中文字体安装

建立存放中文字体库的文件夹

# cd /usr/share/fonts
# mkdir chinese

将字体上传到/usr/share/fonts/chinese
我这里就只安装msyh.ttf,msyhbd.ttf,simhei.ttf,simsun.ttc,Fangsong.ttf。

刷新字体库缓存

#fc-cache

查询已经安装字体

#fc-list
