1.zabbix安装需求：

需求：监控云服务器上的进程

10.10.10.1Zabbix server端2个java进程10.10.10.1Zabbix 客户端3个java进程+MySQL

地址：https://www.zabbix.com/

1.1 安装Zabbix server端

1.2 安装MySQL

systemctl stop firewalld #关闭防火墙服务 systemctl disable firewalld #禁止防火墙服务启动 setenforce = 0 #临时关闭SELinux sed -i s/SELINUX=enforcing/SELINUX=disabled/g /etc/selinux/config #修改将“SELINUX=enforcing”更改为“SELINUX=disabled”，永久关闭SELINUX wget https://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm #下载mysql 5.7安装包 rpm -ivh mysql57-community-release-el7-9.noarch.rpm #安装源 yum install -y mysql-server #安装mysql service mysqld start && chkconfig mysqld on #启动Mysqld服务和设置开机自动启动 grep -an “temporary password” /var/log/mysqld.log #查看初始密码 mysql -u root -p nX6-hKRoLjyW #使用初始密码登陆 mysql: [Warning] Using a password on the command line interface can be insecure. ... Server version: 5.7.29 ... mysql> mysql> alter user root@"localhost" identified by "123qqqWWW"; 修改登陆密码 mysql -uroot -p #使用新密码登陆

1.3.安装Zabbix 5.0监控平台

1.3.1安装Zabbix Yum源仓库

rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm``` yum clean all

1.3.2 安装Zabbix Server 与 Zabbix agent

yum install -y zabbix-server-mysql zabbix-agent #有些云服务器比较慢，这里需要多重试几次。

1.3.3 安装Zabbix frontend

[root@localhost ~]# yum -y install centos-release-scl [root@localhost ~]# vim /etc/yum.repos.d/zabbix.repo ... [zabbix-frontend] name=Zabbix Official Repository frontend - $basearch baseurl=http://repo.zabbix.com/zabbix/5.0/rhel/7/$basearch/frontend enabled=1 //将0修改为1 ...

1.3.4 安装Zabbix前端包

[root@localhost ~]# yum -y install zabbix-web-mysql-scl zabbix-nginx-conf-scl #这里也需要多次重试一下

1.3.5 创建和初始化数据库

[root@localhost ~]# mysql -uroot -p123qqqWWW ... mysql> create database zabbix character set utf8 collate utf8_bin; Query OK, 1 row affected (0.00 sec) mysql> create user zabbix@localhost identified by '123qqqWWW'; Query OK, 0 rows affected (0.00 sec) mysql> grant all privileges on zabbix.* to zabbix@localhost; Query OK, 0 rows affected (0.00 sec) mysql> exit Bye

1.3.6 导入Zabbix数据库结构和数据

[root@localhost ~]# zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p123qqqWWW zabbix

1.3.7 配置Zabbix Server

[root@localhost ~]# vim /etc/opt/rh/rh-nginx116/nginx/conf.d/zabbix.conf server { # listen 80; # server_name example.com; 取消以上两行注释修改后为以下： server { listen 80; server_name example.com; ... 把116行和124行改一下 [root@localhost ~]# vim /etc/zabbix/zabbix_server.conf ... DBUser=zabbix //用户名要与数据库中创建的供zabbix访问的用户名一致 ... DBPassword=123qqq...A //去掉注释，添加创建的zabbix用户的数据库密码 ...

1.3.8 为Zabbix前端配置PHP

[zabbix] user = apache group = apache listen = /var/opt/rh/rh-php72/run/php-fpm/zabbix.sock listen.acl_users = apache,nginx #添加一个nginx listen.allowed_clients = 127.0.0.1 pm = dynamic pm.max_children = 50 pm.start_servers = 5 pm.min_spare_servers = 5 pm.max_spare_servers = 35 php_value[session.save_handler] = files php_value[session.save_path] = /var/opt/rh/rh-php72/lib/php/session/ php_value[max_execution_time] = 300 php_value[memory_limit] = 128M php_value[post_max_size] = 16M php_value[upload_max_filesize] = 2M php_value[max_input_time] = 300 php_value[max_input_vars] = 10000 php_value[date.timezone] = Asia/Shanghai #时区改为Asia/shanghai

1.3.9 开启服务

[root@localhost ~]# systemctl restart zabbix-server zabbix-agent httpd rh-php72-php-fpm [root@localhost ~]# systemctl enable zabbix-server zabbix-agent httpd rh-php72-php-fpm

1.3.10 初始化配置

1.3.11 中文字体乱码的问题

将Win10操作系统C:\Windows\Fonts目录下的任意字体，拷贝到/usr/share/zabbix/assets/fonts/目录下，更改后缀为’.ttf’ 1.在本地操作，先把本地的字体上传到云服务器

scp -r simhei.ttf root@10.10.10.1:/usr/share/zabbix/assets/fonts/

2.在云服务里面操作，然后字体就正常了

ln -s simhei.ttf graphfont.ttf

1.4 在Server端安装zabbix_get

[root@localhost ~]# rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm [root@localhost ~]# yum list |grep zabbix [root@localhost ~]# yum -y install zabbix-get.x86_64

1.5 在被监控的client端Zabbix-agent安装

1.5.1安装Zabbix Yum源仓库

[root@localhost ~]# rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm [root@localhost ~]# yum list all |grep zabbix [root@localhost ~]# yum install -y zabbix-agent

1.5.2 修改配置文件并启动服务

[root@localhost ~]# vim /etc/zabbix/zabbix_agentd.conf 119 Server=127.0.0.1,10.10.10.1. //Zabbix-server地址，多个用","隔开 160 ServerActive=10.10.10.1 //Zabbix-server地址 172 Hostname=10.10.10.2 //本客户端IP地址 [root@localhost ~]# systemctl start zabbix-agent [root@localhost ~]# systemctl enable zabbix-agent [root@localhost ~]# ss -antulp |grep :10050 #查看10050端口有没有打开 tcp LISTEN 0 128 *:10050 *:* users:(("zabbix_agentd",pid=6868,fd=4),("zabbix_agentd",pid=6867,fd=4),("zabbix_agentd",pid=6866,fd=4),("zabbix_agentd",pid=6865,fd=4),("zabbix_agentd",pid=6864,fd=4),("zabbix_agentd",pid=6863,fd=4)) tcp LISTEN 0 128 :::10050 :::* users:(("zabbix_agentd",pid=6868,fd=5),("zabbix_agentd",pid=6867,fd=5),("zabbix_agentd",pid=6866,fd=5),("zabbix_agentd",pid=6865,fd=5),("zabbix_agentd",pid=6864,fd=5),("zabbix_agentd",pid=6863,fd=5))

1.6 在10.10.10.1 server端测试一下

[root@localhost ~]# zabbix_get -s 192.168.43.42 -p 10050 -k system.cpu.load[all,avg1] 0.000000

需要监控服务器里的基本信息的自己百度

2. 监控进程

2.1 java spring进程监控

1. 创建脚本目录，并且给脚本执行权限

[root@localhost ~]# mkdir -p /opt/scripts/ [root@localhost ~]# cd /opt/scripts/ [root@localhost scripts]# ls mysql.sh [root@localhost scripts]# vim java.sh [root@localhost scripts]# cat java.sh #!/bin/bash count=$(ps -ef|grep -Ev "grep|$0"|grep -c java) if [ $count -gt 2 ];then #因为这台服务器有3个java spring进程，这里-gt是小于2 echo '0' else echo '1' fi [root@localhost scripts]# chmod +x java.sh [root@localhost scripts]# bash java.sh

2. 修改脚本存放目录的属主属组为zabbix

[root@localhost opt]# chown -R zabbix.zabbix scripts [root@localhost opt]# ll 总用量 4 drwxr-xr-x 2 zabbix zabbix 4096 Jul 2 17:40 scripts [root@localhost scripts]# chown -R zabbix.zabbix java.sh [root@localhost scripts]# ll -rwxr-xr-x 1 zabbix zabbix 126 Jul 2 16:44 java.sh

3.修改客户端配置文件agentd.conf

[root@localhost ~]# vim /etc/zabbix/zabbix_agentd.conf //添加下面两项 UnsafeUserParameters=1 UserParameter=key_java,/bin/bash /opt/scripts/java.sh

4.重启zabbix_agent

[root@localhost ~]# systemctl restart zabbix-agent [root@localhost ~]# ss -antulp |grep :10050 tcp LISTEN 0 128 *:10050 *:* users:(("zabbix_agentd",pid=6868,fd=4),("zabbix_agentd",pid=6867,fd=4),("zabbix_agentd",pid=6866,fd=4),("zabbix_agentd",pid=6865,fd=4),("zabbix_agentd",pid=6864,fd=4),("zabbix_agentd",pid=6863,fd=4)) tcp LISTEN 0 128 :::10050 :::* users:(("zabbix_agentd",pid=6868,fd=5),("zabbix_agentd",pid=6867,fd=5),("zabbix_agentd",pid=6866,fd=5),("zabbix_agentd",pid=6865,fd=5),("zabbix_agentd",pid=6864,fd=5),("zabbix_agentd",pid=6863,fd=5))

5.在服务端手动测试

[root@localhost ~]# zabbix_get -s 10.10.10.2-k key_java 0

6.配置网页界面，添加监控项以及触发器

查看结果，显示"0"位正常，如果显示"1"时表示出故障了

2.2 MySQL进程监控和java进程监控一致

在这里再添加一行

[root@localhost ~]# vim /etc/zabbix/zabbix_agentd.conf UserParameter=key_java,/bin/bash /opt/scripts/java.sh UserParameter=key_mysql,/bin/bash /opt/scripts/mysql.sh
