一、实验环境:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

[iyunv@zabbixserver ~]# cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core) [iyunv@zabbixserver ~]# uname -r 3.10.0-327.el7.x86_64 [iyunv@zabbixserver ~]# [iyunv@zabbixserver ~]# ifconfig eno16777736 eno16777736: flags=4163  mtu 1500         inet 10.0.0.98  netmask 255.255.255.0  broadcast 10.0.0.255         inet6 fe80::20c:29ff:fef2:d583  prefixlen 64  scopeid 0x20         ether 00:0c:29:f2:d5:83  txqueuelen 1000  (Ethernet)         RX packets 150143  bytes 218651391 (208.5 MiB)         RX errors 0  dropped 0  overruns 0  frame 0         TX packets 30015  bytes 2046005 (1.9 MiB)         TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0 [iyunv@zabbixserver ~]#

二、安装软件包:

1 2 3 4 5 6 7 8

[iyunv@zabbixserver tools]# ll total 65776 -rw-r--r-- 1 root root   523321 Jan 10 10:27 libmcrypt-2.5.7.tar.gz -rw-r--r-- 1 root root 32167628 Nov 28 07:46 mysql-5.6.35.tar.gz -rw-r--r-- 1 root root   910812 Oct 18 11:14 nginx-1.10.2.tar.gz -rw-r--r-- 1 root root 18331135 Aug  6  2015 php-5.6.12.tar.gz -rw-r--r-- 1 root root 15412400 Jan 10 12:01 zabbix-3.0.5.tar.gz [iyunv@zabbixserver tools]#

三、安装步骤
（1）创建用户zabbix

1 2 3 4

[iyunv@zabbixserver ~]# useradd zabbix -s /sbin/nologin [iyunv@zabbixserver ~]# id zabbix uid=1000(zabbix) gid=1000(zabbix) groups=1000(zabbix) [iyunv@zabbixserver ~]#

（2）安装执行编译MySQL的编译工具cmake,（从MySQL5.5以后编译用工具cmake）

1 2	[iyunv@zabbixserver ~]# yum -y install cmake cmake-devel [iyunv@zabbixserver ~]#

（3）创建MySQL用户

1 2 3 4

[iyunv@zabbixserver ~]# useradd mysql -s /sbin/nologin [iyunv@zabbixserver ~]# id mysql uid=1001(mysql) gid=1001(mysql) groups=1001(mysql) [iyunv@zabbixserver ~]#

（4）安装MySQL，用cmake编译，先安装依赖包openssl openssl-devel ncurses ncurses-devel

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

[iyunv@zabbixserver ~]# yum install -y openssl openssl-devel ncurses ncurses-devel [iyunv@zabbixserver ~]# cd tools [iyunv@zabbixserver tools]# tar xf mysql-5.6.35.tar.gz [iyunv@zabbixserver tools]# cd mysql-5.6.35 [iyunv@zabbixserver mysql-5.6.35]# [iyunv@zabbixserver mysql-5.6.35]# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DSYSCONFDIR=/etc -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock -DMYSQL_TCP_PORT=3306 -DENABLED_LOCAL_INFILE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DMYSQL_USER=mysql -DWITH_DEBUG=0 -DWITH_SSL=system [iyunv@zabbixserver mysql-5.6.35]# make && make install

（5）配置MySQL
#修改MySQL安装目录权限

1	[iyunv@zabbixserver mysql-5.6.35]# chown -R mysql.mysql /usr/local/mysql/

#拷贝配置文件

1	[iyunv@zabbixserver mysql-5.6.35]# cp support-files/my-default.cnf /etc/my.cnf

#修改配置文件

1 2 3 4 5 6 7 8 9 10 11

[iyunv@zabbixserver mysql-5.6.35]# vim  /etc/my.cnf [client] port = 3306 socket = /usr/local/mysql/data/socket [mysqld] basedir = /usr/local/mysql datadir = /usr/local/mysql/data port = 3306 server_id = 1 socket = /usr/local/mysql/data/socket [iyunv@zabbixserver mysql-5.6.35]#

#初始化数据库生成数据库基本数据结构

1	[iyunv@zabbixserver mysql-5.6.35]# /usr/local/mysql/scripts/mysql_install_db --defaults-file=/etc/my.cnf --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql

#拷贝MySQL数据库启动脚本，赋可执行权限并设置开机启动

1 2 3 4 5 6

[iyunv@zabbixserver mysql-5.6.35]# cp support-files/mysql.server /etc/init.d/mysqld [iyunv@zabbixserver mysql-5.6.35]# chmod +x /etc/init.d/mysqld [iyunv@zabbixserver mysql-5.6.35]# ll /etc/init.d/mysqld -rwxr-xr-x 1 root root 10875 Jan 10 18:11 /etc/init.d/mysqld [iyunv@zabbixserver mysql-5.6.35]# [iyunv@zabbixserver mysql-5.6.35]# chkconfig mysqld on

#修改PATH变量

1 2 3 4 5

[iyunv@zabbixserver mysql-5.6.35]# echo 'export PATH=/usr/local/mysql/bin:$PATH'>>/etc/profile [iyunv@zabbixserver mysql-5.6.35]# tail -1 /etc/profile export PATH=/usr/local/mysql/bin:$PATH [iyunv@zabbixserver mysql-5.6.35]# source /etc/profile [iyunv@zabbixserver mysql-5.6.35]#

#启动MySQL 测试是否登录

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33

通过浏览器输入http://10.0.0.98进入安装zabbix界面

点击“Next step”

遇到上述错误是因为PHP配置文件/usr/local/php/etc/php.ini的中的默认参数不能满足zabbix要求，这里我们做如下调整:

1 2 3 4 5 6 7 8 9

post_max_size = 32M max_execution_time = 300 max_input_time = 300 date.timezone = "Asia/Shanghai" always_populate_raw_post_data = -1 [iyunv@zabbixserver etc]# service php-fpm restart Gracefully shutting down php-fpm . done Starting php-fpm  done [iyunv@zabbixserver etc]#

然后刷新页面即可,然后下一步

输入密码"zabbix"，下一步

输入"127.0.0.1"之后直接下一步

接着下一步

再下一步

按照提示下载zabbix.conf.php文件放置于/data/web/site/www/conf目录下即可

1 2 3 4 5 6 7 8 9 10 11

刷新页面，点击“finish”完成zabbix服务端的安装


注意:在安装PHP时会出现一些错误，下面是一些常见错误解决方法
安装php遇到问题解决办法:
configure: error: mcrypt.h not found. Please reinstall libmcrypt.
解决办法
wget ftp://mcrypt.hellug.gr/pub/crypt ... mcrypt-2.5.7.tar.gz  

#解压  
tar -zxvf libmcrypt-2.5.7.tar.gz   

#进入目录  
cd libmcrypt-2.5.7  

#编译（默认安装到/usr/local/lib/）  
./configure --prefix=/usr/local/libmcrypt  

#执行安装  
make && make install  


configure: error: Don't know how to define struct flock on this system, set --enable-opcache=no

解决方法一：

查看php官方文档解决. 在configure 里面加上 --with-libdir=lib64

解决方法二：

编辑/etc/ld.so.conf

根据系统，加入include /etc/ld.so.conf，

然后执行ldconfig,使其重新加载一次；(如果出错改为vi /etc/ld.so.conf >> include /usr/local/libmcrytp/lib/)


configure: error: Don't know how to define struct flock on this system, set --enable-opcache=no


解决方法是：
echo /usr/local/mysql/lib >> /etc/ld.so.conf.d/mysql-x86_64.conf
ldconfig -v
