yum -y install rrdtool

service snmpd start

#测试本机snmp启动是否成功

snmpwalk -v 2c -c public localhost

2.mysql安装

cat <<EOF > /etc/yum.repo.d/MariaDB.repo

[mariadb]

name = MariaDB

baseurl = http://yum.mariadb.org/10.1/centos7-amd64

gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB

gpgcheck=1

EOF

yum install MariaDB-server MariaDB-client

systemctl start mariadb

mysql_secure_installation ##passwd cacti

#修改/etc/my.cnf /etc/my.cnf.d/server|client. 修改数据库编码

[client]

default-character-set=utf8

[mysql]

default-character-set=utf8

[mysqld]

collation-server = utf8_unicode_ci

init-connect=’SET NAMES utf8′

character-set-server = utf8

#修改时区

mysql_tzinfo_to_sql /usr/share/zoneinfo/ | mysql -u root -p mysql

#curl -O http://mirror.cogentco.com/pub/apache//httpd/httpd-2.4.29.tar.gz

#tar xzf httpd-2.4.29.tar.gz

#cd httpd-2.4.29

#./configure –prefix=/usr/local/httpd-2.4.29

3.nginx安装

yum install epel-release

yum install nginx

server中配置

location / {

index index.php index.html index.htm;

}

location ~ .php$ {

root html;

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

include fastcgi_params;

}

service nginx start

4.cacti安装

curl -O https://www.cacti.net/downloads/cacti-1.1.28.tar.gz

tar xzf cacti-1.1.28.tar.gz

yum install php-mysql php-snmp php-xml

yum install gcc

yum install libxml2-devel

#download php

./configure –prefix=/usr/local/php-5.6.32

make

make install

#导入数据到数据库

mysqladmin –user=root -p create cacti

mysql -uroot -pcacti -D cacti < /usr/share/nginx/html/cacti-1.1.28/cacti.sql

##add priviledge on mysql.timezone to cacti

mysql -uroot -pcacti <<EOF

GRANT ALL ON cacti.* TO cacti@localhost IDENTIFIED BY ‘12345678’;

GRANT select ON mysql.* TO cacti@localhost IDENTIFIED BY ‘12345678’;

flush privileges;

EOF

#修改cacti的数据库连接配置

vi /usr/share/nginx/html/cacti-1.1.28/include/config.php

#database_username = “cacti”;

#database_password = “12345678”;

useradd cacti

chown -R cacti rra/log/

#增加cacti所需要的mariadb配置

/etc/my.cnf

[client-server]

max_allowed_packet = 16777216

[mysqld]

join_buffer_size = 64M

innodb_buffer_pool_size = 3072M

innodb_doublewrite = OFF

innodb_additional_mem_pool_size = 80M

innodb_flush_log_at_timeout = 3

innodb_read_io_threads = 32

innodb_write_io_threads = 16

max_heap_table_size = 1024M

tmp_table_size = 64M

default-time_zone = Asia/Shanghai

yum install openldap openldap-devel

#其他依赖库在./configure那一步时会有报错提示,根据错误安装相应的包,yum装

cp -frp /usr/lib64/libldap* /usr/lib/

cp -frp /usr/lib64/liblber* /usr/lib/

5.php安装

php去官网下载,解压后进入目录

./configure –prefix=/usr/local/php-5.6.32 –with-snmp –enable-fpm –with-mysql –with-pdo-mysql –enable-sockets –enable-mbstring –with-zlib –with-gmp –with-gd –with-openssl –with-ldap

成功后make && make install

#php,fpm配置

cp /usr/local/php-5.6.32/etc/php-fpm.conf.default /usr/local/php-5.6.32/etc/php-fpm.conf

cp source/php.ini-production /usr/local/php-5.6.32/lib/php.ini

修改配置文件php.ini

date.timezone = “Asia/Shanghai”

#查看ini文件信息

/usr/local/php-5.6.32/bin/php –ini

/usr/local/php-5.6.32/sbin/php-fpm -p /usr/local/php-5.6.32
