将进程杀掉即可：
[root@localhost ~]# kill -5 17043
（4）安装nginx
[root@localhost ~]# yum install nginx -y
（5）开启服务
[root@localhost ~]# systemctl start nginx
[root@localhost ~]# netstat -ntap | grep nginx
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 108485/nginx: maste
[root@localhost ~]# systemctl enable nginx #设为开机自启动
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.
（6）打开网页访问 http://192.168.200.40
2、安装mysql 5.7
（1）安装服务
[root@localhost ~]# yum install -y mariadb-server mariadb
（2）开启服务
[root@localhost ~]# systemctl start mariadb.service
[root@localhost ~]# systemctl enable mariadb.service
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.
（3）进行设置
[root@localhost ~]# 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): #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 #设置密码
New password: #abc123
Re-enter new password: #abc123
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] n #不删除匿名用户
... skipping.
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] n #允许远程登录
... skipping.
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 #不删除测试数据库
... skipping.
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] Y #重新加载
... 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!
//验证密码已经设置好无误

Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies
4、配置nginx支持php
（1）修改php-fpm配置文件，把apache改为nginx
[root@localhost ~]# vim /etc/php-fpm.d/www.conf
#第8行 user = nginx
#第10行 group = nginx
（2）配置location，在index中添加index.php。以支持index.php的首页
[root@localhost ~]# vim /etc/nginx/conf.d/default.conf
#第10行 index index.php index.html index.htm;
#第30~36行
#配置php请求被传送到后端的php-fpm模块，默认情况下php配置块是被注释的，此时去掉注释并修改
#把fastcgi_param中的/scripts改为$document_root。root是配置php程序放置的根目录。
location ~ \.php$ {
root /usr/share/nginx/html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
5、配置php
（1）修改PHP配置文件
[root@localhost ~]# vim /etc/php.ini
#第359行 expose_php = Off //隐藏php版本
#第202行 short_open_tag = On //支持php短标签
//以下为zabbix配置要求
#第368行 max_execution_time = 300 //执行时间
#第378行 max_input_time = 300 //接收数据等待时间
#第389行 memory_limit = 128M //每个脚本占用内存
#第656行 post_max_size = 16M //POST数据大小
#第799行 upload_max_filesize = 2M //下载文件大小
#第800行 always_populate_raw_post_data = -1 //可以用 $HTTP_RAW_POST_DATA 接收post raw data
#第877行 date.timezone = Asia/Shanghai //时区
（2）开启PHP服务并重启nginx服务
[root@localhost ~]# systemctl start php-fpm.service
[root@localhost ~]# systemctl enable php-fpm.service
Created symlink from /etc/systemd/system/multi-user.target.wants/php-fpm.service to /usr/lib/systemd/system/php-fpm.service.
[root@localhost ~]# netstat -ntap | grep 9000
tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 86082/php-fpm: mast
[root@localhost html]# systemctl restart nginx
6、测试首页
（1）写一个简单的测试首页
[root@localhost ~]# vim /usr/share/nginx/html/info.php
<?php
phpinfo();
?>
（2）打开浏览器访问：http://192.168.200.40/info.php
7、测试连接数据库
（1）测试页
[root@localhost ~]# vim /usr/share/nginx/html/info.php
<?php
$link=mysqli_connect('127.0.0.1','root','abc123');
if ($link) echo "连接成功!!";
else echo "连接失败!!";
?>
注：mysql_connect扩展自 PHP 5.5.0 起已废弃，改用mysqli或pdo_mysql
（2）在浏览器刷新：
8、安装zabbix前提
（1）准备zabbix数据库
[root@localhost html]# mysql -uroot -p
ariaDB [(none)]> CREATE DATABASE zabbix character set utf8 collate utf8_bin;
MariaDB [(none)]> GRANT all privileges ON *.* TO 'zabbix'@'%' IDENTIFIED BY 'admin123';
MariaDB [(none)]> flush privileges;
#collate的作用
对于mysql中那些字符类型的列，如VARCHAR,CHAR,TEXT类型的列，都需要有一个COLLATE类型来告知mysql如何对该列进行排序和比较。
（2）检查用户能否登录数据库
[root@localhost ~]# vim /usr/share/nginx/html/info.php
<?php
$link=mysqli_connect('127.0.0.1','zabbix','admin123');
if ($link) echo "Zabbix数据库连接成功!";
else echo "Zabbix数据库连接失败!";
?>
（3）、浏览器刷新，发现Zabbix连接失败
（4）解决以上连接失败的办法
[root@localhost html]# mysql -uroot -p
Enter password:

MariaDB [(none)]> \q
Bye
（5）、重新刷新网页，显示连接成功
二、部署zabbix Server
zabbix 官网 https://www.zabbix.com/download
1、安装yum源
[root@localhost ~]# rpm -i https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm
警告：/var/tmp/rpm-tmp.ReqDjI: 头V4 RSA/SHA512 Signature, 密钥 ID a14fe591: NOKEY
2、安装相关环境包
[root@localhost ~]# yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent -y
3、修改配置文件
[root@localhost ~]# vim /etc/zabbix/zabbix_server.conf
38:LogFile=/var/log/zabbix/zabbix_server.log
49:LogFileSize=0
72:PidFile=/var/run/zabbix/zabbix_server.pid
82:SocketDir=/var/run/zabbix
91:DBHost=localhost //注释去掉
100:DBName=zabbix
116:DBUser=zabbix
124:DBPassword=admin123 //修改本行
356:SNMPTrapperFile=/var/log/snmptrap/snmptrap.log
473:Timeout=4
516:AlertScriptsPath=/usr/lib/zabbix/alertscripts
527:ExternalScripts=/usr/lib/zabbix/externalscripts
563:LogSlowQueries=3000
[root@localhost ~]# grep -n '^'[a-Z] /etc/zabbix/zabbix_server.conf
#检查修改的配置文件是否正确
4、修正图表中文乱码（可选择操作）
[root@localhost ~]# vim /usr/share/zabbix/include/defines.inc.php
:%s /graphfont/kaiti/g #同时按住shift与：键
5、从微软系统下复制相应的字体文件到 /usr/share/zabbix/fonts 目录中注意字体名称要对应配置文件，且注意大小写（可选择操作）
cp STKAITI.TTF /usr/share/zabbix/fonts/
6、赋予权限
cp -r /usr/share/zabbix/ /usr/share/nginx/html/
chown -R zabbix:zabbix /etc/zabbix
chown -R zabbix:zabbix /usr/share/nginx/
chown -R zabbix:zabbix /usr/lib/zabbix/
'//处理指定目录以及其子目录下的所有文件'
chmod -R 755 /etc/zabbix/web/
chmod -R 777 /var/lib/php/session/
'//递归修改文件权限'
7、生成数据库文件,注意密码不要输成root的
[root@localhost zabbix]# zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix
Enter password: #密码admin23
//查看文件是否存在
[root@localhost zabbix]# mysql -uzabbix -p
MariaDB [(none)]> use zabbix;
MariaDB [zabbix]> show tables;
8、修改时区
[root@localhost zabbix]# vim /etc/httpd/conf.d/zabbix.conf
#第20行 php_value date.timezone Asia/Shanghai
9、启动服务
systemctl start zabbix-server.service && systemctl enable zabbix-server.service
systemctl start zabbix-agent.service && systemctl enable zabbix-agent.service
systemctl restart php-fpm.service && systemctl restart nginx
[root@localhost zabbix]# netstat -anpl | grep 10051
tcp 0 0 0.0.0.0:10051 0.0.0.0:* LISTEN 121393/zabbix_serve
tcp 0 0 127.0.0.1:10051 127.0.0.1:58008 TIME_WAIT -
tcp6 0 0 :::10051 :::* LISTEN 121393/zabbix_serve
10、安装后登录 用户名Admin 密码：zabbix
浏览器输入：输入：http://192.168.200.40/zabbix/
[root@localhost web]# chmod -R +x /etc/zabbix/ #赋权
[root@localhost web]# ls
maintenance.inc.php zabbix.conf.php
三、配置 Client 客户端
rpm -Uvh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-2.el7.noarch.rpm
yum -y install zabbix-agent
'//安装zabbix存储库与agent代理服务'
--
vim /etc/zabbix/zabbix_agentd.conf '//修改zabbix代理配置文件'
Server=192.168.200.40 '//98行，指向监控服务器地址'
ServerActive=192.168.200.40 '//139行，指向监控服务器地址'
Hostname=Zabbix-test '//150行，修改名称'
--
systemctl start zabbix-agent.service && systemctl enable zabbix-agent.service
netstat -ntap |grep 'zabbix'
1、Zabbix 监控服务器
可以将界面转换成中文界面
