操做系統：php

[root@mysql ~]# cat /etc/redhat-releasehtml

CentOS Linux release 7.5.1804 (Core)java

Mysql ：版本5.7.23 192.168.75.251node

Zabbix Server：版本3.4.12 192.168.75.250mysql

1、安裝Mysql

1.1下載mysql

關閉防火牆linux

# systemctl stop firewalldc++

# systemctl disable firewalldgit

vi /etc/selinux/configweb

SELINUX=enforcing 改成 SELINUX= disabledredis

Centos7 默認數據庫爲mariadb ，先卸載

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

這個版本須要boost 1.9，也要下載

[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用戶，

groupadd mysql

useradd -g mysql -s /sbin/nologin mysql

1.2安裝依賴包

yum install -y cmake bison bison-devel libaio-devel gcc gcc-c++ git ncurses-devel

1.3編譯

解壓mysql ,把boost的壓縮版放到解壓後的mysql目錄內

tar xzvf mysql-5.7.23.tar.gz

mv boost_1_59_0.tar.gz mysql-5.7.23

進入MySQL源文件目錄，新建configure作爲編譯目錄，並進入該目

cd mysql-5.7.23

mkdir configure

cd configure

使用cmake進行生成編譯環境，

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 \

-DCMAKE_INSTALL_PREFIX=/var/mysql/ \

-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=..

安裝

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

建立日誌文件

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

查看數據文件是否生成

#ll /var/lib/mysql

total 110628

drwxr-x--- 2 mysql mysql 8192 Aug 10 11:06 sys

查看日誌文件是否生成

# ll /var/mysql/log

臨時密碼生成放在 error.log中

# cat /var/mysql/log/error.log

1.5啓動

修改初始密碼、修改環境變量

從模板文件中複製啓動文件：

cp /var/mysql/support-files/mysql.server /etc/init.d/mysqld

修改啓動文件：

vim /etc/init.d/mysqld

找到以下二行：

basedir=

datadir=

修改成：

basedir=/var/mysql/

datadir=/var/lib/mysql

更改權限

#chown -R mysql.mysql /var/mysql /var/lib/mysql

啓動

/etc/init.d/mysqld start

ln -s /var/mysql/bin/mysql /usr/bin

配置MySQL環境變量：

vim /root/.bash_profile

找到下面一行：

PATH=$PATH:$HOME/bin

修改成：

PATH=$PATH:$HOME/bin:/var/mysql/bin

利用上面生成的臨時密碼，登陸

# mysql –u root –p NS0+>RzwvHWl

Welcome to the MySQL monitor. Commands end with ; or \g.

Your MySQL connection id is 6

Server version: 5.7.23

affiliates. Other names may be trademarks of their respective

owners.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql>

更改初始密碼

mysql> alter user 'root'@'localhost' identified by '123456';

2、安裝Zabbix Server

2.1 安裝php

安裝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

檢查當前php的安裝包

yum list installed | grep php

將本地php安裝包卸載乾淨

yum remove php*

默認的yum源沒法升級PHP，須要添加第三方yum源，咱們選擇webtatic庫

rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpm

rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

安裝php7.1

yum install -y php71w

安裝相關插件

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的配置參數

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調整權限，

chmod -R 777 /var/lib/php/session/

2.2 安裝zabbix

安裝依賴包

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

建立zabbix用戶和組

groupadd zabbix

useradd -g zabbix zabbix

編譯、安裝

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和數據庫分離的寫法

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

後期配置文件的參數，根據需求作調整。

把zabbix程序包中的幾個sql文件傳到上面的mysql服務器，導入數據庫文件

[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)服務器上操做

#mysql -u root –p

Enter password:

建立zabbix數據庫，字符集設置爲utf8

mysql>create database zabbix character set utf8 collate utf8_bin;

在mysql數據庫中建立zabbix用戶，賦予zabbix用戶對zabbix數據庫的所有權限，容許zabbix服務器遠程訪問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)

導入數據文件，在控制檯操做

#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主機操做。在上面已經安裝好httpd , 建立apache下建立zabbix目錄

mkdir /var/www/html/zabbix

拷貝zabbix包中的web界面到apache zabbix目錄下

\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/

拷貝zabbix包中服務啓動腳本(server/agentd)到linux系統服務啓動目錄

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修改爲

BASEDIR=/usr/local/zabbix/

設置開機啓動

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服務初始化

http://192.168.75.250/zabbix/setup.php

鏈接數據庫設置，寫mysql服務器所在機器，端口，數據庫名稱，用戶、密碼

3、安裝Zabbix Proxy

首先，在proxy機器上安裝mysql ，跟上面的安裝步驟同樣，只是在導入mysql文件時，只導入一個文件，

#mysql –uzabbix –p zabbix <schema.sql

安裝依賴包

建立zabbix用戶和組

groupadd zabbix

useradd -g zabbix zabbix

編譯、安裝

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 #由於mysql和proxy安裝在同一臺機器

DBName=zabbix

DBUser=zabbix

DBPassword=zabbix
