蓝鲸平台安装环境准备

1、解压安装包

tar xf /root/bkce_src-5.1.29.tar.gz -C /data/

2、解压证书到/data/src/cert/

tar xf /root/bkce_src-5.1.29.tar.gz -C /data/

3、修改install.config.3ip.sample模板

cd /data/install/ && cp install.config.3ip.sample install.config

172.27.16.44 kafka(config),zk(config),es,consul,bkdata(databus),nginx,influxdb,paas,cmdb,job,gse,license,redis,appo
172.27.16.38 kafka(config),zk(config),es,consul,bkdata(dataapi),mongodb,mysql,beanstalk,fta,rabbitmq
172.27.16.88 kafka(config),zk(config),es,consul,bkdata(monitor),appt  

4、配置ssh免密登录

ssh-keygen
1. .ssh 目录权限为：700
2. 密钥文件authorized_keys权限为：600
3. 其他新增密钥文件known_hosts权限为：644
ssh-keygen
ssh-copy-id root@172.27.16.44
cat server.list |xargs -i ssh {} "command"   //server.list为准备安装蓝鲸的服务器资源列表，command为在每台服务器上执行的命令
#蓝鲸平台检查ssh
cd /data/install
bash configure_ssh_without_paas # 根据提示输入各主机的root密码完成免密登录配置

5、批量修改并检查环境准备

cat server.txt |xargs -i ssh {} "which rsync"
cat server.txt |xargs -i ssh {} "systemctl setenforce 0"
cat server.txt |xargs -i ssh {} "sed -i 's/^SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config"
cat server.txt |xargs -i ssh {} "systemctl stop firewalld "
cat server.txt |xargs -i ssh {} "systemctl disable firewalld"
cat server.txt |xargs -i ssh {} "systemctl stop NetworkManager"
cat server.txt |xargs -i ssh {} "systemctl disable NetworkManager"
cat server.txt |xargs -i ssh {} "cat << EOF >> /etc/security/limits.conf
root soft nofile 102400
root hard nofile 102400
EOF"
cat server.txt |xargs -i ssh {} "date -R && timedatectl |grep Time && ulimit -n"
cat server.txt |xargs -i ssh {} "sed -i '2d' /etc/resolv.conf && sed  -i '1i nameserver 127.0.0.1' /etc/resolv.conf"

cat server.txt |xargs -i ssh {} "cat /etc/profile | grep umask"
    umask 002
    umask 022
###
注意：
timedatectl |grep Time #过滤出时区必须为shanghai
timedatectl set-timezone 'Asia/Shanghai'  #修改时区
ntpdate -d cn.pool.ntp.org   #联网修改时间

检查是否存在全局 HTTP 代理
echo "$http_proxy" "$https_proxy"   # 检查 http_proxy https_proxy 变量是否设置，若为空可以跳过后面的操作。
对于本机配置 http_proxy 变量的方式，请依次查找文件 /etc/profile、/etc/bashrc、$HOME/.bashrc 等是否有设置。
env | grep -i proxy     //检查环境变量中是否有http的变量
cat /etc/profile | grep -i proxy*

 

6、添加swap分区

# 使用dd命令创建一个swap分区，在这里创建一个8G大小的分区
dd if=/dev/zero of=/root/swapfile bs=8G count=1
# 格式化新建的分区文件
mkswap /root/swapfile
# 将新建的分区文件设为swap分区
swapon /root/swapfile
# 设置开机自动挂载swap分区
echo "/root/swapfile swap swap defaults 0 0" >> /etc/fstab

7、检查yum配置文件

# CentOS-Epel.repo
[epel]
name=EPEL for redhat/centos $releasever - $basearch
failovermethod=priority
gpgcheck=1
gpgkey=http://mirrors.tencentyun.com/epel/RPM-GPG-KEY-EPEL-7
enabled=1
baseurl=http://mirrors.tencentyun.com/epel/$releasever/$basearch/
# CentOS-Base.repo
[extras]
gpgcheck=1
gpgkey=http://mirrors.tencentyun.com/centos/RPM-GPG-KEY-CentOS-7
enabled=1
baseurl=http://mirrors.tencentyun.com/centos/$releasever/extras/$basearch/
name=Qcloud centos extras - $basearch
[os]
gpgcheck=1
gpgkey=http://mirrors.tencentyun.com/centos/RPM-GPG-KEY-CentOS-7
enabled=1
baseurl=http://mirrors.tencentyun.com/centos/$releasever/os/$basearch/
name=Qcloud centos os - $basearch
[updates]
gpgcheck=1
gpgkey=http://mirrors.tencentyun.com/centos/RPM-GPG-KEY-CentOS-7
enabled=1
baseurl=http://mirrors.tencentyun.com/centos/$releasever/updates/$basearch/

 

8、重启服务器

reboot

小技巧：如何查看当前机器是否为中控机

cat /data/install/.controller_ip

预选可安装的程序

yum -y install pidof pkill rsync gawk curl lsof tar sed iproute uuid psmisc wget bind-utils mysql-devel MySQL-python vim lrzsz
yum -y groupinstall "Development Tools"
