2-27 使用zabbix监控服务器运行状态

Posted 2022-02-24 喝茶等下班

在lnmp下，注意zabbix页面是运行在php下的，所以必须安装PHP

1.

创建zabbix数据库

mysql> create database zabbix;
Query OK, 1 row affected (0.00 sec)

mysql> grant all on zabbix.* to zabbix@localhost identified by zabbix;
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
mysql> set global validate_password_policy=0;
Query OK, 0 rows affected (0.00 sec)

mysql> set global validate_password_length=1;
Query OK, 0 rows affected (0.00 sec)

mysql> grant all on zabbix.* to zabbix@localhost identified by zabbix;
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> \\q
Bye

2.

解压zabbix包

[root@xuegod13 opt]# tar xf zabbix-3.4.3.tar.gz -C /usr/local/src/
[root@xuegod13 opt]# cd /usr/local/src/
[root@xuegod13 src]# ls
boost_1_59_0  mysql-5.7.19  nginx-1.14.2  pcre-8.41  php-7.1.24  zabbix-3.4.3
[root@xuegod13 src]# cd zabbix-3.4.3/
[root@xuegod13 zabbix-3.4.3]# ls
aclocal.m4  compile       configure.ac  include      Makefile.in  README
AUTHORS     conf          COPYING       INSTALL      man          sass
bin         config.guess  database      install-sh   misc         src
build       config.sub    depcomp       m4           missing      upgrades
ChangeLog   configure     frontends     Makefile.am  NEWS

3.

导入zabbix数据库备份

[root@xuegod13 zabbix-3.4.3]# cd database/
[root@xuegod13 database]# ls
ibm_db2  Makefile.am  Makefile.in  mysql  oracle  postgresql  sqlite3
[root@xuegod13 database]# cd mysql/
[root@xuegod13 mysql]# ls
data.sql  images.sql  schema.sql
[root@xuegod13 mysql]# mysql -uzabbix -pzabbix zabbix < schema.sql 
mysql: [Warning] Using a password on the command line interface can be insecure.
[root@xuegod13 mysql]# mysql -uzabbix -pzabbix zabbix < images.sql 
mysql: [Warning] Using a password on the command line interface can be insecure.
[root@xuegod13 mysql]# mysql -uzabbix -pzabbix zabbix < data.sql 
mysql: [Warning] Using a password on the command line interface can be insecure.
[root@xuegod13 mysql]#

注意，这里导入有个顺序，先导入schema.sql 再导入images.sql 最后导入data.sql。顺序不能乱，否则会报错

4.

添加用户和组

[root@xuegod13 opt]# groupadd zabbix
[root@xuegod13 opt]# useradd -s /sbin/nologin -g zabbix zabbix

yum安装插件

#这个是网络管理协议
[root@xuegod13 opt]# yum install -y net-snmp-devel
#安装依赖包
[root@xuegod13 opt]# yum install libevent libevent-devel -y

源码安装

[root@xuegod13 zabbix-3.4.3]# ./configure --prefix=/usr/local/zabbix --enable-server --enable-agent --with-mysql=/var/lib/mysql/bin/mysql_config --with-net-snmp --with-libcurl
#zabbix没有make阶段，直接make install
[root@xuegod13 zabbix-3.4.3]# make install

5.

修改配置文件

[root@xuegod13 zabbix-3.4.3]# ll /usr/local/zabbix/
总用量 0
drwxr-xr-x 2 root root  45 2月  23 18:40 bin
drwxr-xr-x 4 root root 114 2月  23 18:40 etc
drwxr-xr-x 2 root root   6 2月  23 18:40 lib
drwxr-xr-x 2 root root  48 2月  23 18:40 sbin
drwxr-xr-x 4 root root  31 2月  23 18:40 share
[root@xuegod13 zabbix-3.4.3]# cd /usr/local/zabbix/
[root@xuegod13 zabbix]# cd etc/
[root@xuegod13 etc]# ls
zabbix_agentd.conf    zabbix_server.conf
zabbix_agentd.conf.d  zabbix_server.conf.d
[root@xuegod13 etc]# vim zabbix_server.conf
#跳转到85行，修改如下
DBHost=xuegod13
#119行
DBPassword=zabbix
#修改客户端
[root@xuegod13 etc]# vim zabbix_agentd.conf
#280行
UnsafeUserParameters=1

6.

启动脚本

[root@xuegod13 zabbix]# pwd
/usr/local/zabbix
[root@xuegod13 zabbix]# cd sbin/
[root@xuegod13 sbin]# ls
zabbix_agentd  zabbix_server
[root@xuegod13 sbin]# ./zabbix_server   #执行报错

再运行启动zabbix_server脚本，发现成功了

[root@xuegod13 sbin]# ./zabbix_server
