Zabbix安装部署实践

操作系统：

[root@mysql ~]# cat /etc/redhat-release

CentOS Linux release 7.5.1804 (Core)

 

Mysql ：     版本5.7.23  192.168.75.251

Zabbix Server：版本3.4.12  192.168.75.250

 

一、安装Mysql

1.1下载mysql

关闭防火墙

# systemctl   stop firewalld

# systemctl   disable  firewalld

 

vi /etc/selinux/config

SELINUX=enforcing 改为 SELINUX= disabled

 

Centos7 默认数据库为mariadb ，先卸载

rpm –qa |grep   mariadb

mariadb-libs-5.5.56-2.el7.x86_64

rpm -e --nodeps mariadb-libs-5.5.56-2.el7.x86_64

 

这个版本需要boost 1.9，也要下载

[root@mysql soft]# ll

total 132444

-rw-r--r-- 1 root root 83709983 Aug 10 10:26 boost_1_59_0.tar.gz

-rw-r--r-- 1 root root 51907462 Aug 10 10:26 mysql-5.7.23.tar.gz

添加mysql用户，

groupadd mysql

useradd -g mysql -s /sbin/nologin mysql

1.2安装依赖包

yum install -y cmake bison bison-devel libaio-devel gcc gcc-c++ git  ncurses-devel

1.3编译

解压mysql ,把boost的压缩版放到解压后的mysql目录内

 tar xzvf mysql-5.7.23.tar.gz

mv boost_1_59_0.tar.gz   mysql-5.7.23

进入MySQL源文件目录，新建configure做为编译目录，并进入该目

cd mysql-5.7.23

mkdir  configure

cd configure

使用cmake进行生成编译环境，

cmake .. -DBUILD_CONFIG=mysql_release \

-DINSTALL_LAYOUT=STANDALONE \

-DCMAKE_BUILD_TYPE=RelWithDebInfo \

-DENABLE_DTRACE=OFF \

-DWITH_EMBEDDED_SERVER=OFF \

-DWITH_INNODB_MEMCACHED=ON \

-DWITH_SSL=bundled \

-DWITH_ZLIB=system \

-DWITH_PAM=ON \

-DCMAKE_INSTALL_PREFIX=/var/mysql/ \

-DINSTALL_PLUGINDIR="/var/mysql/lib/plugin" \

-DDEFAULT_CHARSET=utf8 \

-DDEFAULT_COLLATION=utf8_general_ci \

-DWITH_EDITLINE=bundled \

-DFEATURE_SET=community \

-DCOMPILATION_COMMENT="MySQL Server (GPL)" \

-DWITH_DEBUG=OFF \

-DWITH_BOOST=..

 

安装

   make && make install

 

修改配置文件

vim /etc/my.cnf

 

 [mysqld]

datadir=/var/lib/mysql

socket=/var/mysql/mysql.sock

port=3306

log_error=/var/mysql/log/error.log

basedir=/var/mysql/

 

[client]

socket=/var/mysql/mysql.sock

 

 

chown  mysql.mysql   /etc/my.cnf

 

创建日志文件

mkdir -p /var/mysql/log

touch /var/mysql/log/error.log

touch /var/mysql/mysql.sock

chown  -R mysql.mysql  /var/mysql/

 

1.4初始化

#/var/mysql/bin/mysqld  --initialize --user=mysql

查看数据文件是否生成

#ll /var/lib/mysql

total 110628

-rw-r----- 1 mysql mysql       56 Aug 10 11:06 auto.cnf

-rw-r----- 1 mysql mysql      417 Aug 10 11:06 ib_buffer_pool

-rw-r----- 1 mysql mysql 12582912 Aug 10 11:06 ibdata1

drwxr-x--- 2 mysql mysql     8192 Aug 10 11:06 performance_schema

drwxr-x--- 2 mysql mysql     8192 Aug 10 11:06 sys

 

查看日志文件是否生成

# ll  /var/mysql/log

临时密码生成放在  error.log中

# cat /var/mysql/log/error.log

1.5启动

修改初始密码、修改环境变量

 

从模板文件中复制启动文件：

cp /var/mysql/support-files/mysql.server /etc/init.d/mysqld

修改启动文件：

vim /etc/init.d/mysqld

找到如下二行：

basedir=

datadir=

修改为：

basedir=/var/mysql/

datadir=/var/lib/mysql

 

更改权限

#chown  -R mysql.mysql  /var/mysql   /var/lib/mysql

启动

/etc/init.d/mysqld start

ln -s /var/mysql/bin/mysql /usr/bin

 

配置MySQL环境变量：

vim /root/.bash_profile

找到下面一行：

PATH=$PATH:$HOME/bin

修改为：

PATH=$PATH:$HOME/bin:/var/mysql/bin

 

利用上面生成的临时密码，登录

# mysql  –u root  –p  NS0+>RzwvHWl

mysql>

 

更改初始密码

mysql> alter user 'root'@'localhost' identified by '123456';

二、安装Zabbix Server

2.1 安装php

安装php7.1版本，zabbix3.0版本要求php5.4及以上。

 

先查看本地php版本

php -v

 

检查当前php的安装包

yum list installed | grep php

 

将本地php安装包卸载干净

yum remove php*

 

默认的yum源无法升级PHP，需要添加第三方yum源，我们选择webtatic库

rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpm

rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

 

安装php7.1

yum install -y php71w

 

安装相关插件

yum install -y php71w-fpm php71w-opcache php71w-cli php71w-gd php71w-imap php71w-mysqlnd php71w-mbstring php71w-mcrypt php71w-pdo php71w-pecl-apcu php71w-pecl-mongodb php71w-pecl-redis php71w-pgsql php71w-xml php71w-xmlrpc php71w-devel mod_php71w   php71w-ldap   php71w-bcmath

 

修改PHP的配置参数

vim /etc/php.ini

date.timezone= Asia/Shanghai

max_execution_time = 300

post_max_size = 32M

memory_limit = 128M

mbstring.func_overload = 1

max_input_time = 300

 

Session调整权限，

chmod  -R 777 /var/lib/php/session/

 

2.2 安装zabbix

安装依赖包

yum -y install gcc* make  curl curl-devel net-snmp  net-snmp-devel perl-DBI httpd mariadb* mysql-devel libxml2-devel curl-devel unixODBC-devel net-snmp-devel OpenIPMI-devel openldap openldap-devel libevent-devel  java-devel  libssh2-devel

 

创建zabbix用户和组

groupadd zabbix

useradd -g zabbix zabbix

 

编译、安装

tar zxvf zabbix-3.4.12.tar.gz

cd zabbix-3.4.12/

 

./configure --prefix=/usr/local/zabbix --enable-server --enable-proxy --enable-agent --enable-ipv6 --with-mysql --with-net-snmp --with-libcurl --with-openipmi --with-unixodbc --with-ldap --with-ssh2 --enable-java

 

make && make install

 

chown  -R   zabbix.zabbix /usr/local/zabbix

 

修改zabbix配置文件

vi /usr/local/zabbix/etc/zabbix_server.conf

 

LogFile=/tmp/zabbix_server.log

DebugLevel=3

DBHost=192.168.75.251    #server和数据库分离的写法

DBName=zabbix

DBUser=zabbix

DBPassword=zabbix

DBSocket=/var/mysql/mysql.sock

DBPort=3306

StartPollers=10

Timeout=4

AlertScriptsPath=/usr/local/zabbix/share/zabbix/alertscripts

LogSlowQueries=3000

CacheSize=1024M

 

后期配置文件的参数，根据需求做调整。

 

把zabbix程序包中的几个sql文件传到上面的mysql服务器，导入数据库文件

[root@zabbix ~]# cd /opt/soft/zabbix-3.4.12/database/mysql

[root@zabbix mysql]# ll

total 4876

-rw-r--r--. 1 1001 1001 2877497 Jul 30 19:41 data.sql

-rw-r--r--. 1 1001 1001 1978341 Jul 30 19:41 images.sql

-rw-r--r--. 1 1001 1001  134791 Jul 30 19:41 schema.sql

[root@zabbix mysql]# scp *  root@192.168.75.251:/opt/

 

下面在mysql(192.168.75.251)服务器上操作

#mysql -u root –p

Enter password:

 

创建zabbix数据库，字符集设置为utf8

mysql>create database zabbix character set utf8 collate utf8_bin;

 

在mysql数据库中创建zabbix用户，赋予zabbix用户对zabbix数据库的全部权限，允许zabbix服务器远程访问mysql

mysql>GRANT ALL PRIVILEGES ON zabbix.* TO zabbix@192.168.75.250 IDENTIFIED BY 'zabbix';

mysql>GRANT ALL PRIVILEGES ON zabbix.* TO zabbix@localhost  IDENTIFIED BY 'zabbix';

mysql> flush privileges ;

mysql> show databases  ;

+--------------------+

| Database           |

+--------------------+

| information_schema |

| mysql              |

| performance_schema |

| sys                |

| zabbix             |

+--------------------+

5 rows in set (0.00 sec)

 

导入数据文件，在控制台操作

#mysql   -u zabbix   -p zabbix <schema.sql

#mysql   -u zabbix   -p zabbix <images.sql

#mysql   -u zabbix   -p zabbix <data.sql

 

2.3 zabbix web部署

回到Zabbix Server主机操作。在上面已经安装好httpd , 创建apache下创建zabbix目录

mkdir /var/www/html/zabbix    

 

拷贝zabbix包中的web界面到apache zabbix目录下

\cp–rf  /opt/soft/zabbix-3.4.12/frontends/php/* /var/www/html/zabbix/   

 

配置web安全

chown -R apache.apache /var/www/html/zabbix

chmod a+x  /var/www/html/zabbix/conf/

 

拷贝zabbix包中服务启动脚本(server/agentd)到linux系统服务启动目录

cp  /opt/soft/zabbix-3.4.12/misc/init.d/fedora/core/zabbix_server  zabbix_agentd/etc/init.d/

 

修改/etc/init.d/zabbix_server和/etc/init.d/zabbix_agentd

 

BASEDIR=/usr/local修改成

BASEDIR=/usr/local/zabbix/

 

设置开机启动

systemctl   enable httpd

systemctl  enable zabbix_server

systemctl  enable zabbix_agentd

 

/etc/init.d/zabbix_server start

/etc/init.d/zabbix_agentd start

systemctl start httpd

 

2.4 web服务初始化

http://192.168.75.250/zabbix/setup.php

连接数据库设置，写mysql服务器所在机器，端口，数据库名称，用户、密码

 

 

 

三、安装Zabbix Proxy

首先，在proxy机器上安装mysql ，跟上面的安装步骤一样，只是在导入mysql文件时，只导入一个文件，

#mysql –uzabbix –p zabbix <schema.sql

 

安装依赖包

yum -y install gcc* make  curl curl-devel net-snmp  net-snmp-devel perl-DBI httpd mariadb* mysql-devel libxml2-devel curl-devel unixODBC-devel net-snmp-devel OpenIPMI-devel openldap openldap-devel libevent-devel java-devel  libssh2-devel

 

创建zabbix用户和组

groupadd zabbix

useradd -g zabbix zabbix

 

编译、安装

tar zxvf zabbix-3.4.12.tar.gz

cd zabbix-3.4.12/

 

./configure --prefix=/opt/server/zabbix_proxy --enable-proxy --enable-agent --enable-ipv6 --with-mysql --with-net-snmp --with-libcurl --with-openipmi --with-unixodbc --with-ldap --with-ssh2 --enable-java

 

make && make install

 

chown  -R   zabbix.zabbix /opt/server/zabbix_proxy

 

配置文件修改

Vi /usr/local/zabbix/etc/zabbix_proxy.conf

 

Server=192.168.75.250

ServerPort=10051

Hostname=zabbix_proxy

LogFile=/tmp/zabbix_proxy.log

DBHost=localhost        #因为mysql和proxy安装在同一台机器

DBName=zabbix

DBUser=zabbix

DBPassword=zabbix

DBSocket=/var/mysql/mysql.sock

ConfigFrequency=60

DataSenderFrequency=60

StartPollers=5

Timeout=4

LogSlowQueries=3000

 

启动proxy(要加入到开机自启)

#/opt/server/zabbix_proxy/sbin/zabbix_proxy-c /opt/server/zabbix_proxy/etc/zabbix_proxy.conf

 

systemctl  enable zabbix_proxy

 

四、启动zabbix_agentd客户端

同上，编译安装zabbix时，客户端也一起编译了，把/usr/local 下面的zabbix目录拷贝到客户端，

修改配置文件

vi /usr/local/zabbix/etc/zabbix_agentd.conf

Server=zabbix_proxy_IP            #建议所以客户端都挂在proxy上，扩展性强

Hostname=zabbix_agentd_hostname  #填写客户端的主机名

 

启动(要加入到开机自启)

/usr/local/zabbix/sbin/zabbix_agentd   -c   /usr/local/zabbix/etc/zabbix_agentd.conf

echo "/usr/local/agent/sbin/zabbix_agentd -c /usr/local/agent/etc/zabbix_agentd.conf" >> /etc/rc.local

 

五、Web管理

添加监控主机

 

 

选择主机监控模版

 

 

 

主机监控成功
