VM NameVM IP AdressCentos_HostNameRole
Centos_wjg1 192.168.1.101 hadoop01 Cloudera Manager Server + Cloudera Manager Agent
Centos_wjg2 192.168.1.102 hadoop02 Cloudera Manager Agent
Centos_wjg6 192.168.1.106 hadoop06 Cloudera Manager Agent

一、配置網(wǎng)絡(luò)環(huán)境

  1. 編輯/etc/sysconfig/network-scripts/ifcfg-eth0配置文件，修改其中以下紅色顏色標(biāo)示的項(xiàng)目：
    vi /etc/sysconfig/network-scripts/ifcfg-eth0
    TYPE=Ethernet
    BOOTPROTO=static
    DEFROUTE=yes
    PEERDNS=yes
    PEERROUTES=yes
    IPV4_FAILURE_FATAL=no
    IPV6INIT=yes
    IPV6_AUTOCONF=yes
    IPV6_DEFROUTE=yes
    IPV6_PEERDNS=yes
    IPV6_PEERROUTES=yes
    IPV6_FAILURE_FATAL=no
    NAME=eth0
    UUID=3719cf03-5d05-454b-903f-e1e26ad34fd6
    DEVICE=eth0
    ONBOOT=yes
    IPADDR=192.168.1.101
    NETWORK=192.168.1.1
    NETSTAT=255.255.255.0
    GATEWAY=192.168.1.1
    DNS1=222.186.160.70
    DNS2=114.114.114.114
    2.編輯/etc/default/grub文件，在GRUB_CMD_LINE_LINUX=""項(xiàng)中，插入"net.ifnames=0 biosdevname=0"（與原有項(xiàng)之間用空格隔開），保存退出。
    3.調(diào)用命令grub2-mkconfig -o /boot/grub2/grub.cfg更新配置，然后直接reboot重啟。
    這樣之后再用ifconfig -a命令查看時(shí)，就有eth0網(wǎng)卡存在了。
  2. 更改hostname
    hostnamectl set-hostname hadoop01
  3. 修改hosts文件
    vi /etc/hosts

192.168.1.101 hadoop01
192.168.1.102 hadoop02
192.168.1.106 hadoop06

  1. 關(guān)閉防火墻
    sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
    setenforce 0
    systemctl stop firewalld.service
    systemctl disable firewalld.service

  2. 配置免密登錄：
    在每臺(tái)主機(jī)上生成rsa公鑰和私鑰
    ssh-keygen -t rsa
    cd .ssh
    cat id_rsa.pub >> authorized_keys
    登錄其他主機(jī)，將其他主機(jī)的公鑰文件內(nèi)容都拷貝到hadoop01主機(jī)上的authorized_keys文件中，命令如下：
    [root@hadoop06 .ssh]# ssh-copy-id -i hadoop01
    /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
    /usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
    wjg@hadoop01's password:

Number of key(s) added: 1

Now try logging into the machine, with: "ssh 'hadoop01'"
and check to make sure that only the key(s) you wanted were added.
在每臺(tái)主機(jī)上重復(fù)以上步驟，使任意兩臺(tái)主機(jī)間都能相互連通。

至此，免密碼登錄已經(jīng)設(shè)定完成。

  1. 更改系統(tǒng)時(shí)間：
    進(jìn)入home目錄，修改.bash_profile
    #setup time region
    TZ='Asia/Shanghai'
    export TZ
    或者: tzselect

將當(dāng)前時(shí)間和日期寫入BIOS，避免重啟后失效
hwclock –w

  1. 配置NTP同步各臺(tái)服務(wù)器的時(shí)間
    9.1主節(jié)點(diǎn)配置

在配置之前，先使用ntpdate手動(dòng)同步一下時(shí)間，免得本機(jī)與對(duì)時(shí)中心時(shí)間差距太大，使得ntpd不能正常同步。這里選用65.55.56.206作為對(duì)時(shí)中心,ntpdate -u ntp1.aliyun.com
vi /etc/ntp.conf
#Hosts on local network are less restricted.
取消下面一行的注釋，并將其中IP和掩碼修改為真實(shí)環(huán)境IP和掩碼，此行配置為允許ntp客戶端連接的配置
restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap
找到server 0.centos.pool.ntp.org iburst，并將所有server配置進(jìn)行注釋
添加下面兩行內(nèi)容
server 127.127.1.0 # local clock
fudge 127.127.1.0 stratum 10

啟動(dòng)NTP服務(wù)
設(shè)置后，重啟ntpd服務(wù)，用ntpstat來檢查效果【大概幾秒鐘就可以看到效果】
#systemctl restart ntpd
#ntpstat

vi /etc/sysconfig/ntpdate
#Set to 'yes' to sync hw clock after successful ntpdate
SYNC_HWCLOCK=yes

9.2 Agent節(jié)點(diǎn)配置
修改/etc/ntp.conf
對(duì)該文件進(jìn)行以下內(nèi)容的修改：
1、注釋所有restrict和server配置
2、添加下面注釋，需要修改以下的IP為NTP服務(wù)器的IP（在本案例中就是server主機(jī)的IP）
server 192.168.1.100

將所有主機(jī)的ntp服務(wù)設(shè)置為開機(jī)自動(dòng)啟動(dòng)
chkconfig ntpd on
systemctl enable ntpd.service

二、 配置163 yum源
1）下載repo文件
cd /etc/yum.repos.d/
wget http://mirrors.163.com/.help/CentOS7-Base-163.repo

2）備份并替換系統(tǒng)的repo文件
mv CentOS-Base.repo CentOS-Base.repo.bak
cp CentOS7-Base-163.repo CentOS-Base.repo

3）執(zhí)行yum源更新命令
yum clean all
yum makecache
yum update

yum install chkconfig python bind-utils psmisc libxslt zlib sqlite cyrus-sasl-plain cyrus-sasl-gssapi fuse fuse-libs redhat-lsb –y

yum install httpd mod_ssl openssl-devel python-psycopg2 –y
yum install MySQL-python
yum install perl
yum install autoconf

三、安裝MySQL:

查看并卸載CentOS系統(tǒng)自帶的MySQL和Mariadb
rpm -qa | grep MySQL
rpm -qa | grep mariadb

rpm -e --nodeps MySQL-python-1.2.5-1.el7.x86_64
rpm -e --nodeps mariadb-libs-5.5.60-1.el7_5.x86_64
下載并上傳以下rpm包到主節(jié)點(diǎn)
MySQL-client-5.6.42-1.el7.x86_64.rpm
MySQL-devel-5.6.42-1.el7.x86_64.rpm
MySQL-server-5.6.42-1.el7.x86_64.rpm
在主節(jié)點(diǎn)上執(zhí)行以下命令安裝MySQL
rpm -ivh MySQL*

安裝完成后啟動(dòng)MySQL:
service mysql start
systemctl start mysql.service

修改MySQL的配置文件
vi /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
transaction-isolation = READ-COMMITTED
#Disabling symbolic-links is recommended to prevent assorted security risks;
#to do so, uncomment this line:
symbolic-links = 0
key_buffer_size = 32M
max_allowed_packet = 32M
thread_stack = 256K
thread_cache_size = 64
query_cache_limit = 8M
query_cache_size = 64M
query_cache_type = 1
max_connections = 550
#expire_logs_days = 10
#max_binlog_size = 100M
#log_bin should be on a disk with enough free space.
#Replace '/var/lib/mysql/mysql_binary_log' with an appropriate path for your
#system and chown the specified folder to the mysql user.
log_bin=/var/lib/mysql/mysql_binary_log
#In later versions of MySQL, if you enable the binary log and do not set
#a server_id, MySQL will not start. The server_id must be unique within
#the replicating group.
server_id=1
binlog_format = mixed
read_buffer_size = 2M
read_rnd_buffer_size = 16M
sort_buffer_size = 8M
join_buffer_size = 8M
#InnoDB settings
innodb_file_per_table = 1
innodb_flush_log_at_trx_commit = 2
innodb_log_buffer_size = 64M
innodb_buffer_pool_size = 4G
innodb_thread_concurrency = 8
innodb_flush_method = O_DIRECT
innodb_log_file_size = 512M
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
sql_mode=STRICT_ALL_TABLES

獲取系統(tǒng)初始密碼：
[root@hadoop01 wjg]# cat /root/.mysql_secret
#The random password set for the root user at Tue Dec 18 20:37:59 2018 (local time): pP4xR06U9nPyWrhA

登錄MySQL:
[root@hadoop01 wjg]# mysql -uroot -ppP4xR06U9nPyWrhA
Warning: Using a password on the command line interface can be insecure.
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 2
Server version: 5.6.42

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('xxxxxxx')

grant all on . to root@"%" identified by " xxxxxxx "

設(shè)置MySQL開機(jī)自啟動(dòng)
systemctl enable mysql.service
初始化MySQL
/usr/bin/mysql_secure_installation

下載mysql-connector-java-5.1.46.tar.gz并解壓
在解壓目錄下找到mysql-connector-java.jar, 復(fù)制到所有主機(jī)的/usr/share/java目錄下
cd mysql-connector-java-5.1.46
cp mysql-connector-java-5.1.46.jar /usr/share/java/mysql-connector-java.jar

[root@hadoop01 usr]# ls -l /usr/share/java/mysql-connector-java.jar
-rw-r--r-- 1 root root 1004838 Dec 19 20:45 /usr/share/java/mysql-connector-java.jar

下載Oracle JDK包oracle-j2sdk1.8-1.8.0+update141-1.x86_64.rpm上傳到所有主機(jī)并安裝
