基于Docker搭建zabbix服务
基于Docker搭建zabbix监控服务环境
操作系统：centos6.5
Docker version 1.7.1
Docker的安装以及pull镜像这里暂且不介绍

我们将用centos6-lamp镜像构建zabbix镜像，注意docker pull镜像时推荐pull centos6的镜像，不要pull默认的centos，因为那是centos7，对于centos7，本人感觉和centos6有好多出入，并不是简简单单的升级，所以推荐docker search centos6
本人是拿pull下来的centos6一键yum安装的lamp环境然后commit为一个新的镜像
Yum安装lamp命令
yum -y install gcc gcc-c++ autoconfhttpd php mysql mysql-server php-mysqlhttpd-manual mod_ssl
mod_perl mod_auth_mysql php-gd php-xml php-mbstring php-ldapphp-pear php-xmlrpc php-bcmath
mysql-connector-odbc mysql-devel libdbi-dbd-mysqlnet-snmp-devel curl-devel unixODBC-devel OpenIPMI-devel java-devel
创建zabbix容器，创建后docker ps可以查看容器的一些基本信息
# docker run -itd --name zabbix -v /mnt/:/mnt/ -p10050:10050 -p 10051:10051 centos6-lamp
fae23d1c5f1c64670ea50bc91f5a444c54ffd823b194187deff279a5ba4ea469
# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
fae23d1c5f1c centos6-lamp "/bin/sh-c '/usr/sb 14 seconds ago Up 11 seconds 22/tcp, 0.0.0.0:10050-10051->10050-10051/tcp zabbix
拷贝宿主主机的zabbix安装包到创建容器时所挂载的数据卷目录
# cp zabbix-2.0.15.tar.gz /mnt/
# docker exec -it zabbix /bin/bash //进入docker容器
bash-4.1# cp /mnt/zabbix-2.0.15.tar.gz /root/
bash-4.1# cd root/
bash-4.1# ls
zabbix-2.0.15.tar.gz
bash-4.1# tar -xzvf zabbix-2.0.15.tar.gz
创建zabbix账户，用户组，yum安装编译安装时需要的依赖包
并编译安装zabbix
bash-4.1# groupadd zabbix -g 201
bash-4.1# useradd -g zabbix -u 201 -m zabbix
bash-4.1# yum install php-pecl-ssh2.x86_64libssh2-devel.x86_64 openldap openldap-devel
bash-4.1# tar -xzvf zabbix-2.0.15.tar.gz
bash-4.1#./configure --prefix=/usr --sysconfdir=/etc/zabbix--enable-server --enable-proxy --enable-agent
--enable-ipv6 --with-mysql=/usr/bin/mysql_config--with-net-snmp --with-libcurl --with-openipmi
--with-unixodbc --with-ldap --with-ssh2 --enable-java //配置
bash-4.1# make && make install //编译&安装
运行mysql服务，配置root用户密码
bash-4.1# mysqladmin -uroot password "root"
mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket'/var/lib/mysql/mysql.sock' (111)'
Check that mysqld is running and that the socket:'/var/lib/mysql/mysql.sock' exists! //这个错误提示mysql服务是否启动
bash-4.1# service mysqld status
mysqld dead but pid file exists //说mysql服务已死，重启就行了
bash-4.1# service mysqld restart
Stopping mysqld:
Starting mysqld:
bash-4.1# service mysqld status
mysqld (pid8224) isrunning...
bash-4.1# mysqladmin -uroot password "root" //更改root密码
创建zabbix数据库，并创建zabbix数据库用户以及授权
bash-4.1# mysql -uroot -proot

导入zabbix数据库到mysql
bash-4.1# mysql -uzabbix -pzabbix zabbix <database/mysql/schema.sql
bash-4.1# mysql -uzabbix -pzabbix zabbix <database/mysql/images.sql
bash-4.1# mysql -uzabbix -pzabbix zabbix <database/mysql/data.sql
拷贝zabbix服务启动脚本到/etc/init.d，并授权
bash-4.1# cp misc/init.d/fedora/core/zabbix_* /etc/init.d/
bash-4.1# chmod 755 /etc/init.d/zabbix_*
修改服务脚本参数
bash-4.1# sed -i "s#BASEDIR=/usr/local#BASEDIR=/usr/#g"/etc/init.d/zabbix_server
bash-4.1# sed -i "s#BASEDIR=/usr/local#BASEDIR=/usr/#g"/etc/init.d/zabbix_agentd
创建zabbix日志目录，并授权
bash-4.1# mkdir /var/log/zabbix
bash-4.1# chown zabbix:zabbix/var/log/zabbix/
配置PHP 环境，修改PHP.INI
vim /etc/php.ini (修改这些参数的目的是zabbix 的web 代码要求要这么配置才能正
常运行，所以，不修改饿后果就是安装无法获得正常的环境，关于php.ini 这些参数的具体
意思，请读者自行参考php 相关资料)
date.timezone = Asia\/Shanghai
max_execution_time = 300
post_max_size = 32M
max_input_time = 300
memory_limit = 128M
mbstring.func_overload = 0
另外直接sed命令更改配置文件也行
sed -i "s/;date.timezone =/date.timezone =Asia\/Shanghai/g" /etc/php.ini
sed -i "s#max_execution_time = 30#max_execution_time =300#g" /etc/php.ini
sed -i "s#post_max_size = 8M#post_max_size = 32M#g"/etc/php.ini
sed -i "s#max_input_time = 60#max_input_time =300#g" /etc/php.ini
sed -i "s#memory_limit = 128M#memory_limit =128M#g" /etc/php.ini
sed -i "/;mbstring.func_overload =2/ambstring.func_overload = 0\n" /etc/php.ini
设置HTTPD，MYSQLD开机启动并开启服务
chkconfig mysqld on
chkconfig httpd on
service mysqld start
service httpd start
配置ZABBIX_SERVER.CONF文件
SED更改
sed -i"s/DBUser\=root/DBUser\=zabbix/g"/etc/zabbix/zabbix_server.conf
sed -i "/#DBPassword=/aDBPassword=zabbix\n"/etc/zabbix/zabbix_server.conf
sed -i" s#tmp/zabbix_server.log#var/log/zabbix/zabbix_server.log#g"/etc/zabbix/zabbix_server.conf
主要的4个参数，vim 更改/etc/zabbix_server.conf文件
LogFile=/tmp/zabbix_server.log
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix
DBSocket=/var/lib/mysql/mysql.sock
配置ZABBIX_AGENTD.CONF文件
Sed配置
sed -i "s/Server\=127.0.0.1/Server\=127.0.0.1,192.168.1.89/g"
/etc/zabbix/zabbix_agentd.conf
sed -i"s/ServerActive\=127.0.0.1/ServerActive\=192.168.1.89:10051/g"
/etc/zabbix/zabbix_agentd.conf
sed -i"s#tmp/zabbix_agentd.log#var/log/zabbix/zabbix_agentd.log#g"
/etc/zabbix/zabbix_agentd.conf
sed -i"#UnsafeUserParameters=0#aUnsafeUserParameters=1\n"
/etc/zabbix/zabbix_agentd.conf
建议的参考配置
vim /etc/zabbix/zabbix_agentd.conf
LogFile=/var/log/zabbix/zabbix_agentd.log
EnableRemoteCommands=0
Server=127.0.0.1,192.168.1.89
StartAgents=8
ServerActive=192.168.1.89:10051
Hostname=nat.kx1d.com
Timeout=30
Include=/etc/zabbix/zabbix_agentd.conf.d/
UnsafeUserParameters=1
拷贝网页文件到网站目录，并启动服务
bash-4.1# cp -r frontends/php/* /var/www/html/
bash-4.1# /etc/init.d/zabbix_server start
Starting zabbix_server:
bash-4.1# /etc/init.d/zabbix_agentd start
Starting zabbix_agentd:zabbix_agentd :/usr/local/etc/zabbix_agentd.userparams.conf: No such file or directory
按常规来走，已经可以访问访问http://宿主主机-ip/zabbix进行配置，但是因为创建容器时忘记映射80端口所以现在是不能访问配置的，不得不docker commit成新的镜像，然后利用新镜像创建新容器
# docker commit zabbix centos6-zabbix-v1
8567daabbc620ac4314135412385ffa017eb3f96a04c43a854c6733f269de86a
# docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
centos6-zabbix-v1latest 8567daabbc62 43 secondsago 1.693 GB
# docker rm -f zabbix
Zabbix //删除原来的zabbix容器，因为容器名字是唯一的，不删除会报错
创建新容器，10050端口映射可选（如果zabbix对外开发，那么就映射，只是在docker容器之间用的话，可以不选）
root@gmdai ~]# docker run -itd --name zabbix -v /mnt/:/mnt/ -p10050:10050-p 80:80 centos6-lamp
cb65aed2b86af4d7d8fad75fd97f37c38249dc5387e2effc53003ee7d101f2a7
# docker exec -it zabbix /bin/bash
重启mysqld httpd这些服务，修改zabbix-agentd-conf参数为Server=127.0.0.1,192.168.1.89 ServerActive=192.168.1.89:10051新容器启动时的ip地址
重启zabbix-server zabbix-agentd服务
再次访问进行配置就行了
配置zabbix时出现date(): Itis not safe to rely on the system's timezone settings的报错，网上找了答案是在php.ini中设置date.timezone的值为PRC，设置好以后的为：date.timezone=PRC，同时取消这一行代码的注释，即去掉前面的分号就可以了。
遗留问题docker容器的ip不是固定的每次重启都会重新分配
