Greenplum6.x重新初始化
2024-04-29 15:09:45
换一种初始化方式
一. 规划目录
root用户登录操作
#master机器
mkdir -p /datax/master
chown gpadmin:gpadmin -R /datax/master
#standby 机器
mkdir -p /datax/master
chown gpadmin:gpadmin -R /datax/master
#两台segment机器
mkdir -p /datax/primary
mkdir -p /datax/mirrorchown gpadmin:gpadmin -R /datax若之前目录下存在文件，清理
root登录master机器
# master
[gpadmin@mdw ~]$ su - gpadmin
#删除master的目录
[gpadmin@mdw ~]$ rm -rf /datax/master/*
#删除standby目录
[gpadmin@mdw ~]$ gpssh -h smdw -e 'rm -rf /datax/master/*'
[smdw] rm -rf /datax/master/*
[gpadmin@mdw ~]$# 清理segment上的内容
[gpadmin@mdw ~]$ gpssh -f /tmp/seg_hosts
=> rm -rf /datax/primary/*
[sdw1]
[sdw2]
=> rm -rf /datax/mirror/*
[sdw1]
[sdw2]
=> rm -rf /datax/tbs_tmp/*
[sdw1]
[sdw2]
=> rm -rf /datax/tbs_tmp2/*
[sdw1]
[sdw2]
=> rm -f /tmp/.s.PGSQL.*.lock
[sdw1]
[sdw2]
=>=> exit二. 编辑初始化文件
root用户登录master机器操作
编辑配置文件,无mirror镜像
vi /tmp/gpinitsystem_config_no_mirror
#添加如下内容
ARRAY_NAME="gpdb"
SEG_PREFIX=gpseg
PORT_BASE=36000
declare -a DATA_DIRECTORY=(/datax/primary /datax/primary /datax/primary /datax/primary)MASTER_HOSTNAME=mdw
MASTER_DIRECTORY=/datax/master
MASTER_PORT=5432
TRUSTED_SHELL=ssh
CHECK_POINT_SEGMENTS=8
ENCODING=UNICODE
修改配置文件
root用户登录master机器操作
注意这里的路径是/datax
su - gpadmin
# 检查 MASTER_DATA_DIRECTORY
[gpadmin@mdw ~]$ cat ~/.bash_profile | grep MASTER_DATA_DIRECTORY
[gpadmin@mdw ~]$ cat ~/.bashrc | grep MASTER_DATA_DIRECTORY# 修改.bashrc
[gpadmin@mdw ~]$ vi ~/.bashrc#将MASTER_DATA_DIRECTORY换成最新的路径
export MASTER_DATA_DIRECTORY=/datax/master/gpseg-1
export PGPORT=5432
export PGDATABASE=gpdb
export LD_PRELOAD=/lib64/libz.so.1 ps# 修改.bash_profile
[gpadmin@mdw ~]$ vi ~/.bash_profile
# 修改内容如下datax
export MASTER_DATA_DIRECTORY=/datax/master/gpseg-1#分发gpscp -f /tmp/hostlist ~/.bashrc =:~
gpscp -f /tmp/hostlist ~/.bash_profile =:~三. 执行初始化
gpadmin登录master机器
1. 执行安装master和standby
# 这里使用-h 参数
[gpadmin@mdw ~]$ gpinitsystem -c /tmp/gpinitsystem_config_no_mirror -h /tmp/seg_hosts -s smdw --mirror-mode=spread
初始化日志
[gpadmin@mdw tmp]$ gpinitsystem -c /tmp/gpinitsystem_config_no_mirror -h /tmp/seg_hosts -s smdw --mirror-mode=spread
