2準備工作
2.1關閉防火牆（已關閉）
sudo service iptables stop
sudo chkconfig iptablesoff
2.2關閉SELinux
1) 修改配置檔案/etc/selinux/config
sudo vim /etc/selinux/config # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=disabled # SELINUXTYPE= can take one of these two values: # targeted - Targeted processes are protected, # mls - Multi Level Security protection. SELINUXTYPE=targeted
2）重啟伺服器
sudoreboot
3 Zabbix-server/agent編譯及安裝
3.1建立使用者
sudo groupadd --system zabbix
sudo useradd --system -g zabbix -d /usr/lib/zabbix -s /sbin/nologin -c "Zabbix Monitoring System" zabbix
3.2上傳zabbix安裝包並解壓
將安裝包上傳至/opt/software路徑並解壓到當前路徑
tar -zxvf zabbix-4.2.8.tar.gz
3.3建立zabbix資料庫和表
1）進入/opt/software/zabbix-4.2.8/database/mysql路徑
cd/opt/software/zabbix-4.2.8/database/mysql
2）進入MySQL客戶端執行建表語句，並匯入zabbix提供的sql指令碼
mysql> create database zabbix default character set utf8 collate utf8_bin; use zabbix; source schema.sql; source data.sql; source images.sql;
3.4 編譯環境準備
1）上傳並安裝安裝MySQL相關rpm包
sudo rpm -ivh MySQL-devel-5.6.24-1.el6.x86_64.rpm sudo rpm -ivh MySQL-embedded-5.6.24-1.el6.x86_64.rpm sudo rpm -ivh MySQL-shared-5.6.24-1.el6.x86_64.rpm sudo rpm -ivh MySQL-shared-compat-5.6.24-1.el6.x86_64.rpm
2）安裝所需依賴
sudo rpm -ivh http://www.city-fan.org/ftp/contrib/yum-repo/rhel6/x86_64/city-fan.org-release-2-1.rhel6.noarch.rpm sudo yum-config-manager --enable city-fan.org sudo rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/Packages/l/libnghttp2-1.6.0-1.el6.1.x86_64.rpm sudo rpm -e --nodeps libxml2-python-2.7.6-21.el6.x86_64 sudo yum install -y libcurl libcurl-devel libxml2 libxml2-devel net-snmp-devel libevent-devel pcre-devel gcc-c++
3.5編譯及安裝
1）進入/opt/software/zabbix-4.2.8路徑
cd/opt/software/zabbix-4.2.8
2）編譯安裝

sudo make install
3.6修改配置檔案
1）修改zabbix-server配置檔案
sudo vim /usr/local/etc/zabbix_server.conf DBHost=hadoop102 DBName=zabbix DBUser=root DBPassword=123456
2）修改zabbix-agent配置檔案
sudo vim /usr/local/etc/zabbix_agentd.conf Server=hadoop102 #ServerActive=127.0.0.1 #Hostname=Zabbix server
3.7 編寫系統服務指令碼
1）編輯zabbix-server檔案
sudovim/etc/init.d/zabbix-server
2）內容如下
#!/bin/sh # # chkconfig: - 85 15 # description: Zabbix server daemon # config: /usr/local/etc/zabbix_server.conf # ### BEGIN INIT INFO # Provides: zabbix # Required-Start: $local_fs $network # Required-Stop: $local_fs $network # Default-Start: # Default-Stop: 0 1 2 3 4 5 6 # Short-Description: Start and stop Zabbix server # Description: Zabbix server ### END INIT INFO # Source function library. . /etc/rc.d/init.d/functions if [ -x /usr/local/sbin/zabbix_server ]; then exec=/usr/local/sbin/zabbix_server else exit 5 fi prog=zabbix_server conf=/usr/local/etc/zabbix_server.conf pidfile=/tmp/zabbix_server.pid timeout=10 if [ -f /etc/sysconfig/zabbix-server ]; then . /etc/sysconfig/zabbix-server fi lockfile=/var/lock/subsys/zabbix-server start() { echo -n $"Starting Zabbix server: " daemon $exec -c $conf rv=$? echo [ $rv -eq 0 ] && touch $lockfile return $rv } stop() { echo -n $"Shutting down Zabbix server: " killproc -p $pidfile -d $timeout $prog rv=$? echo [ $rv -eq 0 ] && rm -f $lockfile return $rv } restart() { stop start } case "$1" in start|stop|restart) $1 ;; force-reload) restart ;; status) status -p $pidfile $prog ;; try-restart|condrestart) if status $prog >/dev/null ; then restart fi ;; reload) action $"Service ${0##*/} does not support the reload action: " /bin/false exit 3 ;; *) echo $"Usage: $0 {start|stop|status|restart|try-restart|force-reload}" exit 2 ;; esac
3）加執行許可權
sudochmod+x /etc/init.d/zabbix-server
4）編輯zabbix-agent檔案
sudovim/etc/init.d/zabbix-agent
5）內容如下
#!/bin/sh # # chkconfig: - 86 14 # description: Zabbix agent daemon # processname: zabbix_agentd # config: /usr/local/etc/zabbix_agentd.conf # ### BEGIN INIT INFO # Provides: zabbix-agent # Required-Start: $local_fs $network # Required-Stop: $local_fs $network # Should-Start: zabbix zabbix-proxy # Should-Stop: zabbix zabbix-proxy # Default-Start: # Default-Stop: 0 1 2 3 4 5 6 # Short-Description: Start and stop Zabbix agent # Description: Zabbix agent ### END INIT INFO # Source function library. . /etc/rc.d/init.d/functions if [ -x /usr/local/sbin/zabbix_agentd ]; then exec=/usr/local/sbin/zabbix_agentd else exit 5 fi prog=zabbix_agentd conf=/usr/local/etc/zabbix_agentd.conf pidfile=/tmp/zabbix_agentd.pid timeout=10 if [ -f /etc/sysconfig/zabbix-agent ]; then . /etc/sysconfig/zabbix-agent fi lockfile=/var/lock/subsys/zabbix-agent start() { echo -n $"Starting Zabbix agent: " daemon $exec -c $conf rv=$? echo [ $rv -eq 0 ] && touch $lockfile return $rv } stop() { echo -n $"Shutting down Zabbix agent: " killproc -p $pidfile -d $timeout $prog rv=$? echo [ $rv -eq 0 ] && rm -f $lockfile return $rv } restart() { stop start } case "$1" in start|stop|restart) $1 ;; force-reload) restart ;; status) status -p $pidfile $prog ;; try-restart|condrestart) if status $prog >/dev/null ; then restart fi ;; reload) action $"Service ${0##*/} does not support the reload action: " /bin/false exit 3 ;; *) echo $"Usage: $0 {start|stop|status|restart|try-restart|force-reload}" exit 2 ;; esac
