LNMP架构基础上zabbix监控平台部署！
前言
一：zabbix部署
- 主机分配
| 主机 | IP地址 | 部署服务 |
|---|---|---|
| server | 192.168.233.136 | LNMP、zabbix |
| client | 192.168.233.137 | zabbix代理 |
1.1：开局优化
-
关闭防火墙、网络管理、主机名修改（server、client），仅展示server操作
[root@192 ~]# hostnamectl set-hostname server [root@192 ~]# su [root@server ~]# [root@server ~]# systemctl stop firewalld && systemctl disable firewalld Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service. Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service. [root@server ~]# setenforce 0 && sed -i "s/SELINUX=*/SELINUX=disabled/g" /etc/selinux/config [root@server ~]# systemctl stop NetworkManager && systemctl disable NetworkManager Removed symlink /etc/systemd/system/multi-user.target.wants/NetworkManager.service. Removed symlink /etc/systemd/system/dbus-org.freedesktop.NetworkManager.service. Removed symlink /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service. Removed symlink /etc/systemd/system/network-online.target.wants/NetworkManager-wait-online.service.
1.2：LNMP安装环境（使用yum安装的方式）
-
nagios是一款比较老的监控工具，但是因为插件太多，不是主流
cacti是一款图形化的监控分析工具
zabbix是基于web界面的提供分布式功能的监控工具，监控上线是300-500台
zabbix可以监控网络设备（例如思科、华为等）、服务器（例如IBM、联想、戴尔等）、应用监控（Apache、MQ、中间件、Tomcat等）和服务（HTTP、https、nginx、ssl等）等监控
zabbix使用的最稳定的版本是4.0，LTS是指测试，5.0版本在官网下载的时候比4.0版本多了一个nginx服务器的选择
ajax：异步刷新
zcat：不解压直接查看压缩包
-
1、安装nginx
[root@server ~]# wget http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm '//下载nginx软件包' [root@server ~]# vim /etc/yum.repos.d/nginx.repo '//编辑yum源' [nginx-stable] name=nginx stable repo baseurl=http://nginx.org/packages/centos/$releasever/$basearch/ gpgcheck=0 enabled=1 [root@server ~]# yum clean all 已加载插件：fastestmirror, langpacks 正在清理软件源： base extras nginx-stable updates Cleaning up list of fastest mirrors [root@server ~]# yum makecache '//建立yum缓存' [root@server ~]# systemctl start nginx [root@server ~]# systemctl enable nginx Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service. -
网页测试：发现nginx搭建成功

2、安装mysql（mariadb）
[root@server ~]# yum -y install mariadb-server mariadb [root@server ~]# systemctl start mariadb.service [root@server ~]# systemctl enable mariadb.service Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service. [root@server ~]# netstat -ntap |grep 3306 tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 95170/mysqld '//接下来执行mysql安全配置向导' [root@server ~]# mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): '//初次运行直接回车' OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MariaDB root user without the proper authorisation. Set root password? [Y/n] y '//y。设置密码' New password: '//输入密码' Re-enter new password: '//重复输入一次' Password updated successfully! Reloading privilege tables.. ... Success! By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? [Y/n] y '//是否删除匿名用户，建议y删除' ... Success! Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] y '//是否禁止root远程登录，建议y禁止' ... Success! By default, MariaDB comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? [Y/n] n '//是否删除test数据库，根据实际情况' ... skipping. Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? [Y/n] y '//是否重新加载权限表，建议y' ... Success! Cleaning up... All done! If you've completed all of the above steps, your MariaDB installation should now be secure. Thanks for using MariaDB! [root@server ~]# mysql -uroot -p '//测试登陆mysql数据库' Enter password: Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 8 Server version: 5.5.65-MariaDB MariaDB Server Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others. Type 'help;' or '\h' for help.

3、安装PHP
[root@server ~]# rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm '//升级rpm包' 获取https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm 警告：/var/tmp/rpm-tmp.xsEbUC: 头V3 RSA/SHA256 Signature, 密钥 ID 352c64e5: NOKEY 准备中... ################################# [100%] 正在升级/安装... 1:epel-release-7-12 ################################# [100%] [root@server ~]# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm 获取https://mirror.webtatic.com/yum/el7/webtatic-release.rpm 警告：/var/tmp/rpm-tmp.YidqBL: 头V4 RSA/SHA1 Signature, 密钥 ID 62e74ca5: NOKEY 准备中... ################################# [100%] 正在升级/安装... 1:webtatic-release-7-3 ################################# [100%] [root@server ~]# cd /etc/yum.repos.d/ [root@server yum.repos.d]# yum -y install php72w php72w-devel php72w-fpm php72w-gd php72w-mbstring php72w-mysql '//安装PHP环境工具包' [root@server yum.repos.d]# php -v '//查看版本' PHP 7.2.27 (cli) (built: Jan 26 2020 15:49:49) ( NTS ) Copyright (c) 1997-2018 The PHP Group Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies -
4、配置php-fpm.d模块的配置文件与nginx配置文件并关联
[root@server yum.repos.d]# vim /etc/php-fpm.d/www.conf user = nginx '//8行将apache修改为nginx' ; RPM: Keep a group allowed to write in log dir. group = nginx '//10行将apache修改为nginx' [root@server yum.repos.d]# vim /etc/nginx/conf.d/default.conf '//修改nginx配置文件与php相关联' index index.php index.html index.htm; '//第10行添加index.php文件' ...省略内容 '//下方是30-36行的字段，为配置php请求被传送到后端的php-fpm模块的配置' location ~ \.php$ { root /usr/share/nginx/html; '//修改站点目录' fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; 34 fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; '//将fastcgi_param中的/scripts改为$document_root，root是配置php程序纺织的根目录' include fastcgi_params; } -
5、优化PHP配置文件
[root@server yum.repos.d]# vim /etc/php.ini short_open_tag = On '//202行改为On，支持php短标签' expose_php = Off '//359修改为Off，隐藏php版本' '//以下都是zabbix的配置要求' max_execution_time = 300 '//执行时间，在一个程序执行的过程中能够等待的执行时间，执行时间过程中如果没有执行完会结束该程序，以防出现卡死，默认30秒' max_input_time = 300 '//378行，接受数据的等待时间' memory_limit = 128M '//389行，每个脚本的占用内存限制' post_max_size = 16M '//656行，post数据的最大限制' upload_max_filesize = 2M '//799，下载文件的大小限制' always_populate_raw_post_data = -1 '//800行添加此句，可以用$HTTP_RAW_POST_DATA接受post raw data（原始未处理数据）' date.timezone = Asia/Shanghai '//878行，修改时区为上海' [root@server yum.repos.d]# systemctl start php-fpm [root@server yum.repos.d]# systemctl enable php-fpm Created symlink from /etc/systemd/system/multi-user.target.wants/php-fpm.service to /usr/lib/systemd/system/php-fpm.service. [root@server yum.repos.d]# netstat -ntap |grep 9000 tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 96130/php-fpm: mast [root@server yum.repos.d]# systemctl restart nginx -
6、编写PHP测试首页并测试网页
[root@server yum.repos.d]# vim /usr/share/nginx/html/info.php <?php phpinfo(); ?>
