客快物流大数据项目(三十一)：常用工具安装
目录
常用工具安装
一、安装依赖包
如果不提前安装这些依赖包，在后面安装CM的时候可能会出现异常。
yum install -y cyrus-sasl-plain cyrus-sasl-gssapi portmap fuse-libs bind-utils libxslt fuse
yum install -y /lib/lsb/init-functions createrepo deltarpm python-deltarpm
yum install -y mod_ssl openssl-devel python-psycopg2 MySQL-python二、安装Apache
yum install httpd createrepo
systemctl start httpd
systemctl status httpd三、添加MySQL驱动包
mkdir /usr/share/java
cp /export/softwares/jars/mysql-connector-java-5.1.44.jar /usr/share/java/mysql-connector-java.jar四、禁用交换空间
临时生效： |
|---|
sysctl -w vm.swappiness=10 |
永久生效： |
echo "vm.swappiness=10" >> /etc/sysctl.conf |
五、禁用透明页
临时生效： |
|---|
echo never > /sys/kernel/mm/transparent_hugepage/defrag echo never > /sys/kernel/mm/transparent_hugepage/enabled |
永久生效： |
echo "echo never > /sys/kernel/mm/transparent_hugepage/defrag" >> /etc/rc.local echo "echo never > /sys/kernel/mm/transparent_hugepage/enabled" >> /etc/rc.local |
六、配置本地Parcel存储库
创建/opt/cloudera/parcel-repo目录，将下载好的parcel和manifest.json文件放置到该目录，然后执行下面的命令： |
|---|
mkdir -p /opt/cloudera/parcel-repo |
cd /export/softwares/cdh-6.2.1/ |
cp *parcel* manifest.json /opt/cloudera/parcel-repo/ |
注意：需要将.sha1校验文件复制一份为.sha |
|---|
cp CDH-6.2.1-1.cdh6.2.1.p0.1425774-el7.parcel.sha1 CDH-6.2.1-1.cdh6.2.1.p0.1425774-el7.parcel.sha |
mkdir -p /var/www/html/cloudera-repo |
cd /export/softwares/cdh-6.2.1/ |
cp *rpm RPM-GPG-KEY-cloudera manifest.json /var/www/html/cloudera-repo |
cd /var/www/html/cloudera-repo |
|---|
执行：createrepo . |
七、配置CM的YUM源
vi /etc/yum.repos.d/cloudera-manager.repo（此时不存在该文件，确保文件内容为如下） |
|---|
[cloudera-manager] name=Cloudera Manager 6.2.1 baseurl=http://node2/cloudera-repo/ gpgkey=http://node2/cloudera-repo/RPM-GPG-KEY-cloudera gpgcheck=1 enabled=1 autorefresh=0 type=rpm-md |
然后执行：yum clean all && yum makecache |
八、安装CDH所需要的依赖包
yum install edhat-lsb portmap mod_ssl openssl-devel python-psycopg2 MySQL-python chkconfig bind-utils libxslt zlib sqlite cyrus-sasl-plain cyrus-sasl-gssapi fuse fuse-libs九、安装MySQL
wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm |
|---|
yum localinstall mysql57-community-release-el7-8.noarch.rpm yum install mysql-community-server systemctl start mysqld systemctl status mysqld |
grep 'temporary password' /var/log/mysqld.log //会生成临时密码 |
mysql -uroot -p”sZlks?>yp2L>” |
|---|
取消mysql密码规范限制 |
set global validate_password_policy=0; |
set global validate_password_length=1; |
重设密码 |
|---|
alter user 'root'@'localhost' identified by '123456'; |
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION; |
flush privileges; |
退出mysql客户端，使用新密码重新登录 |
mysql -uroot -p123456 |
十、安装JDK
tar -zxf /export/softwares/jdk-8u221-linux-x64.tar.gz -C /usr/java/ ln -s /usr/java/jdk1.8.0_221 /usr/java/jdk |
|---|
vim /etc/profile |
export JAVA_HOME=/usr/java/jdk export PATH=.:$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH |
source /etc/profile |
