部署doris集群，详细步骤

1、下载

    我下载的是预编译版本，可以省去编译的时间。

    可以从百度下载：Palo文档PALO - 预编译版本下载 | Doris (baidu.com)

    ![](https://img-blog.csdnimg.cn/c484ea72f9b54ae6b7325828aaa1de0f.png)

    也可以从doris官网下载（推荐）： Download - Apache Doris

    ![](https://img-blog.csdnimg.cn/c348d659280b40089862ecd5d59f8d5c.png) 

     我是从doris官网下载的1.1.5版本

2、安装

    **2.1 解压、设置环境变量**

    下载完之后是两个压缩包（be 和 fe ）

    ![](https://img-blog.csdnimg.cn/a4994c99e24e48c1b1cecea1407873f7.png)

    将其上传到服务器，解压到目标路径。我部署的是一主三从，所以是n1节点(fe & be) ，n2 节点（be）, n3 节点（be) 。

    配置环境变量：        

#DORIS_HOME
export DORIS_HOME=/opt/doris/fe/
export DORIS_HOME=/opt/doris/be/
export PATH=$PATH:$DORIS_HOME/bin

** 2.2 修改fe配置文件**

PPROF_TMPDIR="$DORIS_HOME/log/"

# INFO, WARNING, ERROR, FATAL
sys_log_level = INFO

# ports for admin, web, heartbeat service 
be_port = 9060
webserver_port = 8040
heartbeat_service_port = 9050
brpc_port = 8060

priority_networks = 192.168.8.001/24
storage_root_path = /doris-data1.hdd,890;/doris-data2.ssd,890;/doris-data3.ssd,890
max_tablet_version_num = 5000
max_compaction_threads = 16

cumulative_size_based_promotion_size_mbytes = 2048
row_step_for_compaction_merge_log = 1
total_permits_for_compaction_score = 50000

# Choose one if there are more than one ip except loopback address. 
# Note that there should at most one ip match this list.
# If no ip match this rule, will choose one randomly.

# data root path, separate by ';'
# you can specify the storage medium of each root path, HDD or SSD
# you can add capacity limit at the end of each root path, seperate by ','
# eg:
# storage_root_path = /home/disk1/doris.HDD,50;/home/disk2/doris.SSD,1;/home/disk2/doris
# /home/disk1/doris.HDD, capacity limit is 50GB, HDD;
# /home/disk2/doris.SSD, capacity limit is 1GB, SSD;
# /home/disk2/doris, capacity limit is disk capacity, HDD(default)
# 
# you also can specify the properties by setting '<property>:<value>', seperate by ','
# property 'medium' has a higher priority than the extension of path
#
# Default value is ${DORIS_HOME}/storage, you should create it by hand.
storage_root_path = ${DORIS_HOME}/storage

# Advanced configurations
sys_log_dir = ${DORIS_HOME}/log
# sys_log_roll_mode = SIZE-MB-1024
# sys_log_roll_num = 10
# sys_log_verbose_modules = *
# log_buffer_level = -1
# palo_cgroups 

然后只需要将be的配置同步到其他节点就可以了。

3、启动

** 3.1 启动fe**

cd /opt/doris/fe/bin/

./start_fe.sh

    启动fe之后能在主节点看到如下进程说明主节点启动成功：

     然后可以打开网页访问 192.168.8.001:8030 ，第一次登录，用户名是root，没有密码。

** 3.2 启动fe**

     第一次启动be可能会启动失败，这时需要修改最大文件句柄数

echo "* soft nofile 204800" >> /etc/security/limits.conf
echo "* hard nofile 204800" >> /etc/security/limits.conf

echo "* soft nproc 204800" >> /etc/security/limits.conf
echo "* hard nproc 204800 " >> /etc/security/limits.conf

修改 /etc/sysctl.conf, 加入
echo fs.file-max = 6553560 >> /etc/sysctl.conf

     查看是否成功

cat /etc/security/limits.conf
cat /etc/sysctl.conf

     重启生效

reboot -h now

    还有一种观念是之前某次启动的时候，因为错误操作导致进程一直占用doris的be端口号,解决办法：重启或： 

netstat -ntulp

    找到be端口号对应的进程号，然后kill -9 关闭该进程 （比如图中的38233），关闭之后重启。

4、添加be

  可以在web页面操作，也可以通过mysql客户端工具通过9030连接到doris

** 添加BE**

ALTER SYSTEM ADD BACKEND "hostname:9050"; ** **

** 查看BE状态**

SHOW PROC '/backends';
