操作系统：
[root@mysql ~]# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core)
Mysql ： 版本5.7.23 192.168.75.251
Zabbix Server：版本3.4.12 192.168.75.250
一、安装Mysql
1.1下载mysql
关闭防火墙
# systemctl stop firewalld
# systemctl disable firewalld
vi /etc/selinux/config
SELINUX=enforcing 改为 SELINUX= disabled
Centos7 默认数据库为mariadb ，先卸载
rpm –qa |grep mariadb
mariadb-libs-5.5.56-2.el7.x86_64
rpm -e --nodeps mariadb-libs-5.5.56-2.el7.x86_64
这个版本需要boost 1.9，也要下载
[root@mysql soft]# ll
total 132444
-rw-r--r-- 1 root root 83709983 Aug 10 10:26 boost_1_59_0.tar.gz
-rw-r--r-- 1 root root 51907462 Aug 10 10:26 mysql-5.7.23.tar.gz
添加mysql用户，
groupadd mysql
useradd -g mysql -s /sbin/nologin mysql
1.2安装依赖包
yum install -y cmake bison bison-devel libaio-devel gcc gcc-c++ git ncurses-devel
1.3编译
解压mysql ,把boost的压缩版放到解压后的mysql目录内
tar xzvf mysql-5.7.23.tar.gz
mv boost_1_59_0.tar.gz mysql-5.7.23
进入MySQL源文件目录，新建configure做为编译目录，并进入该目
cd mysql-5.7.23
mkdir configure
cd configure
使用cmake进行生成编译环境，
cmake .. -DBUILD_CONFIG=mysql_release
-DINSTALL_LAYOUT=STANDALONE
-DCMAKE_BUILD_TYPE=RelWithDebInfo
-DENABLE_DTRACE=OFF
-DWITH_EMBEDDED_SERVER=OFF
-DWITH_INNODB_MEMCACHED=ON
-DWITH_SSL=bundled
-DWITH_ZLIB=system
-DWITH_PAM=ON

-DINSTALL_PLUGINDIR="/var/mysql/lib/plugin"
-DDEFAULT_CHARSET=utf8
-DDEFAULT_COLLATION=utf8_general_ci
-DWITH_EDITLINE=bundled
-DFEATURE_SET=community
-DCOMPILATION_COMMENT="MySQL Server (GPL)"
-DWITH_DEBUG=OFF
-DWITH_BOOST=..
安装
make && make install
修改配置文件
vim /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/mysql/mysql.sock
port=3306
log_error=/var/mysql/log/error.log
basedir=/var/mysql/
[client]
socket=/var/mysql/mysql.sock
chown mysql.mysql /etc/my.cnf
创建日志文件
mkdir -p /var/mysql/log
touch /var/mysql/log/error.log
touch /var/mysql/mysql.sock
chown -R mysql.mysql /var/mysql/
1.4初始化
#/var/mysql/bin/mysqld --initialize --user=mysql
查看数据文件是否生成
#ll /var/lib/mysql

1.5启动
修改初始密码、修改环境变量
从模板文件中复制启动文件：
cp /var/mysql/support-files/mysql.server /etc/init.d/mysqld
修改启动文件：
vim /etc/init.d/mysqld
找到如下二行：
basedir=
datadir=
修改为：
basedir=/var/mysql/
datadir=/var/lib/mysql
更改权限
#chown -R mysql.mysql /var/mysql /var/lib/mysql
启动
/etc/init.d/mysqld start
ln -s /var/mysql/bin/mysql /usr/bin
配置MySQL环境变量：
vim /root/.bash_profile
找到下面一行：
PATH=$PATH:$HOME/bin
修改为：
PATH=$PATH:$HOME/bin:/var/mysql/bin
利用上面生成的临时密码，登录
# mysql –u root –p NS0+>RzwvHWl

更改初始密码
mysql> alter user 'root'@'localhost' identified by '123456';
二、安装Zabbix Server
2.1 安装php
安装php7.1版本，zabbix3.0版本要求php5.4及以上。
先查看本地php版本
php -v
检查当前php的安装包
yum list installed | grep php
将本地php安装包卸载干净
yum remove php*
默认的yum源无法升级PHP，需要添加第三方yum源，我们选择webtatic库
rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
安装php7.1
yum install -y php71w
安装相关插件
yum install -y php71w-fpm php71w-opcache php71w-cli php71w-gd php71w-imap php71w-mysqlnd php71w-mbstring php71w-mcrypt php71w-pdo php71w-pecl-apcu php71w-pecl-mongodb php71w-pecl-redis php71w-pgsql php71w-xml php71w-xmlrpc php71w-devel mod_php71w php71w-ldap php71w-bcmath
修改PHP的配置参数
vim /etc/php.ini
date.timezone= Asia/Shanghai
max_execution_time = 300
post_max_size = 32M
memory_limit = 128M
mbstring.func_overload = 1
max_input_time = 300
Session调整权限，
chmod -R 777 /var/lib/php/session/
2.2 安装zabbix
安装依赖包
yum -y install gcc* make curl curl-devel net-snmp net-snmp-devel perl-DBI httpd mariadb* mysql-devel libxml2-devel curl-devel unixODBC-devel net-snmp-devel OpenIPMI-devel openldap openldap-devel libevent-devel java-devel libssh2-devel
创建zabbix用户和组
groupadd zabbix
useradd -g zabbix zabbix
编译、安装
tar zxvf zabbix-3.4.12.tar.gz
cd zabbix-3.4.12/
./configure --prefix=/usr/local/zabbix --enable-server --enable-proxy --enable-agent --enable-ipv6 --with-mysql --with-net-snmp --with-libcurl --with-openipmi --with-unixodbc --with-ldap --with-ssh2 --enable-java
make && make install
chown -R zabbix.zabbix /usr/local/zabbix
修改zabbix配置文件
vi /usr/local/zabbix/etc/zabbix_server.conf
LogFile=/tmp/zabbix_server.log
DebugLevel=3
DBHost=192.168.75.251 #server和数据库分离的写法
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix
DBSocket=/var/mysql/mysql.sock
DBPort=3306
StartPollers=10
Timeout=4
AlertScriptsPath=/usr/local/zabbix/share/zabbix/alertscripts
LogSlowQueries=3000
CacheSize=1024M
后期配置文件的参数，根据需求做调整。
把zabbix程序包中的几个sql文件传到上面的mysql服务器，导入数据库文件
[root@zabbix ~]# cd /opt/soft/zabbix-3.4.12/database/mysql
[root@zabbix mysql]# ll
total 4876
-rw-r--r--. 1 1001 1001 2877497 Jul 30 19:41 data.sql
-rw-r--r--. 1 1001 1001 1978341 Jul 30 19:41 images.sql
-rw-r--r--. 1 1001 1001 134791 Jul 30 19:41 schema.sql
[root@zabbix mysql]# scp * root@192.168.75.251:/opt/
下面在mysql(192.168.75.251)服务器上操作
#mysql -u root –p
Enter password:
创建zabbix数据库，字符集设置为utf8
mysql>create database zabbix character set utf8 collate utf8_bin;
在mysql数据库中创建zabbix用户，赋予zabbix用户对zabbix数据库的全部权限，允许zabbix服务器远程访问mysql
mysql>GRANT ALL PRIVILEGES ON zabbix.* TO zabbix@192.168.75.250 IDENTIFIED BY 'zabbix';
mysql>GRANT ALL PRIVILEGES ON zabbix.* TO zabbix@localhost IDENTIFIED BY 'zabbix';
mysql> flush privileges ;
mysql> show databases ;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| sys |
| zabbix |
+--------------------+
5 rows in set (0.00 sec)
导入数据文件，在控制台操作
#mysql -u zabbix -p zabbix <schema.sql
#mysql -u zabbix -p zabbix <images.sql
#mysql -u zabbix -p zabbix <data.sql
2.3 zabbix web部署
回到Zabbix Server主机操作。在上面已经安装好httpd , 创建apache下创建zabbix目录
mkdir /var/www/html/zabbix
拷贝zabbix包中的web界面到apache zabbix目录下
cp–rf /opt/soft/zabbix-3.4.12/frontends/php/* /var/www/html/zabbix/
配置web安全
chown -R apache.apache /var/www/html/zabbix
chmod a+x /var/www/html/zabbix/conf/
拷贝zabbix包中服务启动脚本(server/agentd)到linux系统服务启动目录
cp /opt/soft/zabbix-3.4.12/misc/init.d/fedora/core/zabbix_server zabbix_agentd/etc/init.d/
修改/etc/init.d/zabbix_server和/etc/init.d/zabbix_agentd
BASEDIR=/usr/local修改成
BASEDIR=/usr/local/zabbix/
设置开机启动
systemctl enable httpd
systemctl enable zabbix_server
systemctl enable zabbix_agentd
/etc/init.d/zabbix_server start
/etc/init.d/zabbix_agentd start
systemctl start httpd
2.4 web服务初始化
http://192.168.75.250/zabbix/setup.php
连接数据库设置，写mysql服务器所在机器，端口，数据库名称，用户、密码
三、安装Zabbix Proxy
首先，在proxy机器上安装mysql ，跟上面的安装步骤一样，只是在导入mysql文件时，只导入一个文件，
#mysql –uzabbix –p zabbix <schema.sql
安装依赖包
yum -y install gcc* make curl curl-devel net-snmp net-snmp-devel perl-DBI httpd mariadb* mysql-devel libxml2-devel curl-devel unixODBC-devel net-snmp-devel OpenIPMI-devel openldap openldap-devel libevent-devel java-devel libssh2-devel
创建zabbix用户和组
groupadd zabbix
useradd -g zabbix zabbix
编译、安装
tar zxvf zabbix-3.4.12.tar.gz
cd zabbix-3.4.12/
./configure --prefix=/opt/server/zabbix_proxy --enable-proxy --enable-agent --enable-ipv6 --with-mysql --with-net-snmp --with-libcurl --with-openipmi --with-unixodbc --with-ldap --with-ssh2 --enable-java
make && make install
chown -R zabbix.zabbix /opt/server/zabbix_proxy
配置文件修改
Vi /usr/local/zabbix/etc/zabbix_proxy.conf
Server=192.168.75.250
ServerPort=10051
Hostname=zabbix_proxy
LogFile=/tmp/zabbix_proxy.log
DBHost=localhost #因为mysql和proxy安装在同一台机器
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix
DBSocket=/var/mysql/mysql.sock
ConfigFrequency=60
DataSenderFrequency=60
StartPollers=5
Timeout=4
LogSlowQueries=3000
启动proxy(要加入到开机自启)
#/opt/server/zabbix_proxy/sbin/zabbix_proxy-c /opt/server/zabbix_proxy/etc/zabbix_proxy.conf
systemctl enable zabbix_proxy
四、启动zabbix_agentd客户端
同上，编译安装zabbix时，客户端也一起编译了，把/usr/local 下面的zabbix目录拷贝到客户端，
修改配置文件
vi /usr/local/zabbix/etc/zabbix_agentd.conf
Server=zabbix_proxy_IP #建议所以客户端都挂在proxy上，扩展性强
Hostname=zabbix_agentd_hostname #填写客户端的主机名
启动(要加入到开机自启)
/usr/local/zabbix/sbin/zabbix_agentd -c /usr/local/zabbix/etc/zabbix_agentd.conf
echo "/usr/local/agent/sbin/zabbix_agentd -c /usr/local/agent/etc/zabbix_agentd.conf" >> /etc/rc.local
五、Web管理
添加监控主机
选择主机监控模版
主机监控成功
