mysql-client客户端安装

1、修改YUM仓库

vim /etc/yum.repos.d/my.repo

[epel]

name=epel

baseurl=https://mirrors.aliyun.com/epel/7Server/x86_64/

enabled=1

gpgcheck=0

2、安装cobbler

yum install dhcp httpd xinetd tftp cobbler cobbler-web -y

3、修改cobbler配置文件

生成加密密码：openssl passwd -1 -salt bw.com 123456

vim /etc/cobbler/settings

server: 192.168.100.100

next_server: 192.168.100.100

default_password_crypted: "$1$stu.com$Pp0HQwZhSF...mXIxjJAH." #root管理员密码

4、配置DHCP

vim /etc/dhcpd/dhcp.conf

option domain-name "stu.com";

option domain-name-servers 192.168.100.100;

default-lease-time 36000;

max-lease-time 72000;

log-facility local7;

subnet 192.168.100.0 netmask 255.255.255.0 {

range 192.168.100.110 192.168.100.150;

option routers 192.168.100.1;

option broadcast-address 192.168.100.255;

next-server 192.168.100.100;

filename "pxelinux.0";

}

systemctl start dhcpd

systemctl enable dhcpd

5、配置tftp

vim /etc/xinetd.d/tftp

disable= no

systemctl start xinetd

systemctl enable xinetd

6、下载启动引导文件

cobbler get-loaders

7、导入光盘镜像文件

cobbler import --path=/mnt/cdrom --name=c75 --arch=x86_64

vim /var/lib/cobbler/kickstarts/c75.ks

#platform=x86, AMD64, Intel EM64T

#version=DEVEL

#Install OS instead of upgrade

install

#Keyboard layouts

keyboard 'us'

#Root password

rootpw --iscrypted $default_password_crypted #见第3步

#System timezone

timezone Asia/Shanghai

#Use network installation

url --url=$tree

#System language

lang en_US.UTF-8

#Firewall configuration

firewall --disabled

#System authorization information

auth --useshadow --enablemd5

#Use graphical install

text

firstboot --disable

#SELinux configuration

selinux --disabled

#Reboot after installation

reboot

#System bootloader configuration

bootloader --location=mbr

#Clear the Master Boot Record

zerombr

#Partition clearing information

clearpart --all --initlabel

#Disk partitioning information

part /boot --fstype="xfs" --size=256

part swap --fstype="swap" --size=1024

part / --fstype="xfs" --ondisk=sda --size=1 --grow #使用全部剩余空间

#Network information

$SNIPPET('network_config')

%pre

$SNIPPET('log_ks_pre')

$SNIPPET('kickstart_start')

$SNIPPET('pre_install_network_config')

#Enable installation monitoring

$SNIPPET('pre_anamon')

%end

%packages@^minimal

br>@core

bash-completion

vim

net-tools

bind-utils

tree

lrzsz

wget

telnet

-postfix

%end

%addon com_redhat_kdump --disable --reserve-mb='auto'

%end

%post

#Start yum configuration

$yum_config_stanza

#End yum configuration

%end

%post

sed -i "1s/5/0/" /etc/default/grub

grub2-mkconfig -o /boot/grub2/grub.cfg

rm -f /etc/yum.repos.d/CentOS*

yum remove NetworkManager -y

%end

二、cobbler配置

1、编辑profile

cobbler profile edit --name=c75-x86_64 --kickstart=/var/lib/cobbler/kickstarts/c75.ks

cobbler profile edit --name=c75-x86_64 --kopts='net.ifnames=0 biosdevname=0 ipv6.disable=1'

2、客户端默认local启动

vim /etc/cobbler/pxe/pxedefault.template

DEFAULT menu

PROMPT 0

MENU TITLE Cobbler | http://cobbler.github.io/

TIMEOUT 1

TOTALTIMEOUT 6000

ONTIMEOUT $pxe_timeout_profile

LABEL local

MENU LABEL (local)

MENU DEFAULT

LOCALBOOT -1

$pxe_menu_items

MENU end

cobbler system add --name=default --profile=c75-x86_64

cobbler sync

3、配置IP信息及主机名

cobbler system add --name=lbmaster --profile=c75-x86_64 --kickstart=/var/lib/cobbler/kickstarts/c75.ks \

--interface=eth0 --static=1 --mac=00:50:56:20:38:C8 --ip-address=192.168.100.10 --subnet=255.255.255.0 --gateway=192.168.100.1 \

--name-servers="192.168.100.100" --hostname=lbmaster.stu.com

4、配置YUM仓库

(1)同步网络YUM仓库

cobbler repo add --name=openstack --mirror=https://mirrors.aliyun.com/centos/7.5.1804/cloud/x86_64/openstack-ocata/ --arch=x86_64 --breed=yum

cobbler repo add --name=zabbix --mirror=https://mirrors.aliyun.com/zabbix/zabbix/3.5/rhel/7/x86_64/ --arch=x86_64 --breed=yum

cobbler reposync

cobbler profile edit --name=c75-x86_64 --kickstart=/var/lib/cobbler/kickstarts/c75-cobbler.ks --repos="openstack"

测试、生产环境中，有时并不需要在本地安装一个mysql server服务，只需要安装一个登录mysql server 的mysql的客户端client

centos6系统上安装mysql-client的方式：

yum install mysql-clent mysql-devel -y

centos7的系统上安

测试、生产环境中，有时并不需要在本地安装一个mysql server服务，只需要安装一个登录mysql server 的mysql的客户端client

centos6系统上安装mysql-client的方式：

yum install mysql-clent mysql-devel -y

centos7的系统上安装mysql client的方式：

yum install -y mariadb.x86_64 mariadb-libs.x86_64

装mysql client的方式：

yum install -y mariadb.x86_64 mariadb-libs.x86_64

/> crontab -e

cobbler reposync --tries=3 --no-fail

(2)修改默认YUM仓库配置文件

vim /var/www/cobbler/ks_mirror/config/c75-x86_64.repo

[core-0]name=core-0

baseurl=http://@@http_server@@/cobbler/ks_mirror/c75-x86_64
br>name=core-0

baseurl=http://@@http_server@@/cobbler/ks_mirror/c75-x86_64

gpgcheck=0

priority=$yum_distro_priority

[epel]

names=epel

baseurl=https://mirrors.aliyun.com/epel/7Server/x86_64/

enabled=1

gpgcheck=0

systemctl start cobblerd

systemctl enable cobblerd

cobbler sync
