hbase-1.0.0-cdh5.4.4伪分布配置

下面是为了安装hbase对ubuntu系统做的一些配置

1) 配置hadoop管理用户asn可以同时可以使用的最大文件句柄数和文件可以被引用的进程数上限

/etc/security/limits.conf 配置  参考 http://blog.csdn.net/taijianyu/article/details/5976319

# /etc/security/limits.conf
#
#Each line describes a limit for a user in the form:
#
#<domain>        <type>  <item>  <value>
#
#Where:
#<domain> can be:
#        - a user name
#        - a group name, with @group syntax
#        - the wildcard *, for default entry
#        - the wildcard %, can be also used with %group syntax, for maxlogin limit
#        - NOTE: group and wildcard limits are not applied to root.
#          To apply a limit to the root user, <domain> must be the literal username root.
#
#<type> can have the two values:
#        - "soft" for enforcing the soft limits
#        - "hard" for enforcing hard limits
#
#<item> can be one of the following:
#        - core - limits the core file size (KB)
#        - data - max data size (KB)
#        - fsize - maximum filesize (KB)
#        - memlock - max locked-in-memory address space (KB)
#        - nofile - max number of open files
#        - rss - max resident set size (KB)
#        - stack - max stack size (KB)
#        - cpu - max CPU time (MIN)
#        - nproc - max number of processes
#        - as - address space limit (KB)
#        - maxlogins - max number of logins for this user
#        - maxsyslogins - max number of logins on the system
#        - priority - the priority to run user process with
#        - locks - max number of file locks the user can hold
#        - sigpending - max number of pending signals
#        - msgqueue - max memory used by POSIX message queues (bytes)
#        - nice - max nice priority allowed to raise to values: [-20, 19]
#        - rtprio - max realtime priority
#        - chroot - change root to directory (Debian-specific)
#
#<domain>      <type>  <item>         <value>
#

#*               soft    core            0
#root            hard    core            100000
#*               hard    rss             10000
#@student        hard    nproc           20
#@faculty        soft    nproc           20
#@faculty        hard    nproc           50
#ftp             hard    nproc           0
#ftp             -       chroot          /ftp
#@student        -       maxlogins       4
asn              -       nofile         32768
asn              -       nproc          16384

# End of file

参考oracle11gr2安装中对oracle用户的文件句柄和进程的限制

 #vim /etc/security/limits.conf 在文件后增加
  Oracle            soft    nproc           2047
  Oracle            hard    nproc           16384
  Oracle            soft    nofile          1024
  Oracle            hard    nofile          65536
  Oracle            soft    stack           10240 

type：有 soft，hard 和 -

　　soft 指的是当前系统生效的设置值

　　hard 表明系统中所能设定的最大值

　　用 - 就表明同时设置了 soft 和 hard 的值

在/etc/pam.d/common-session文件中添加 session required pam_limits.so，重新登录使更改生效

#
# /etc/pam.d/common-session - session-related modules common to all services
#
# This file is included from other service-specific PAM config files,
# and should contain a list of modules that define tasks to be performed at the start and end of sessions of *any* kind (both interactive and non-interactive).
#
# As of pam 1.0.1-6, this file is managed by pam-auth-update by default.
# To take advantage of this, it is recommended that you configure any local modules either before or after the default block,
# and use pam-auth-update to manage selection of other modules.
# See pam-auth-update(8) for details.

# here are the per-package modules (the "Primary" block)
session [default=1]                     pam_permit.so
# here's the fallback if no module succeeds
session requisite                       pam_deny.so
# prime the stack with a positive return value if there isn't one already;
# this avoids us returning an error just because nothing sets a success code
# since the modules above will each just jump around
session required                        pam_permit.so
# The pam_umask module will set the umask according to the system default in
# /etc/login.defs and user settings, solving the problem of different
# umask settings with different shells, display managers, remote sessions etc.
# See "man pam_umask".
session optional                        pam_umask.so
# and here are more per-package modules (the "Additional" block)
session required        pam_unix.so
session optional        pam_systemd.so

session required        pam_limits.so
# end of pam-auth-update config

 2) 修改内核参数

在/etc/sysctl.conf文件后增加

# Uncomment the next two lines to enable Spoof protection (reverse-path filter)
# Turn on Source Address Verification in all interfaces to prevent some spoofing attacks
#net.ipv4.conf.default.rp_filter=1
#net.ipv4.conf.all.rp_filter=1

# Uncomment the next line to enable TCP/IP SYN cookies
# See http://lwn.net/Articles/277146/
# Note: This may impact IPv6 TCP sessions too
#net.ipv4.tcp_syncookies=1

# Uncomment the next line to enable packet forwarding for IPv4
#net.ipv4.ip_forward=1

# Uncomment the next line to enable packet forwarding for IPv6
#  Enabling this option disables Stateless Address Autoconfiguration
#  based on Router Advertisements for this host
#net.ipv6.conf.all.forwarding=1

###################################################################
# Additional settings - these settings can improve the network
# security of the host and prevent against some network attacks
# including spoofing attacks and man in the middle attacks through redirection.
# Some network environments, however, require that these settings are disabled so review and enable them as needed.
#
# Do not accept ICMP redirects (prevent MITM attacks)
#net.ipv4.conf.all.accept_redirects = 0
#net.ipv6.conf.all.accept_redirects = 0
# _or_
# Accept ICMP redirects only for gateways listed in our default
# gateway list (enabled by default)
# net.ipv4.conf.all.secure_redirects = 1
#
# Do not send ICMP redirects (we are not a router)
#net.ipv4.conf.all.send_redirects = 0
#
# Do not accept IP source route packets (we are not a router)
#net.ipv4.conf.all.accept_source_route = 0
#net.ipv6.conf.all.accept_source_route = 0
#
# Log Martian Packets
#net.ipv4.conf.all.log_martians = 1
#

fs.aio-max-nr = 1048576
fs.file-max = 6553600

参考oracle11gr2安装中的内核参数配置

#vim /etc/sysctl.conf 在文件最后增加 
 fs.aio-max-nr = 1048576 
 fs.file-max = 6553600 
 kernel.shmall = 2097152 
 kernel.shmmax = 2147483648 
 kernel.shmmni = 4096 
 kernel.sem = 250 32000 100 128 
 net.ipv4.ip_local_port_range = 1024 65000 
 net.core.rmem_default = 262144 
 net.core.rmem_max = 4194304 
 net.core.wmem_default = 262144 
 net.core.wmem_max = 1048586 
 保存文件。 
 #/sbin/sysctl -p          //让参数生效

3) 指定DataNode中用于传进、传出数据的最大线程数

在hdfs-site.xml中配置属性 dfs.datanode.max.transfer.threads值为4096

2 conf目录下文件配置

1）hbase-env.sh

配置JAVA_HOME环境变量

解注export HBASE_MANAGES_ZK=true，让hbase管理它自己的zookeeper实例（即启用hbase内置的zookeeper）

2）hbase-site.xml

<configuration>
    <property>
        <name>hbase.rootdir</name>
        <value>hdfs://hadoop2:8020/hbase</value>
    </property>
    <property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
    </property>

　　<property>
　　　　<name>hbase.tmp.dir</name>
　　　　<value>/home/asn/tmp/hbase-asn</value>
　　</property>
    <property>
        <name>hbase.zookeeper.quorum</name>
        <value>hadoop2</value>
    </property>
    <property>
        <name>hbase.zookeeper.property.dataDir</name>
        <value>/home/asn/zookeeperdata</value>
    </property>
</configuration>

3) regionservers

hadoop2

4)启动日志
