cacti 是网络监控用的一个工具
1.依赖包
yum mariadb nginx snmpd
yum -y install net-snmp
yum -y install net-snmp-utils
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

#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
mv cacti-1.1.28 /usr/share/nginx/html/
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
