摘要：這里只演示修改下運(yùn)行停掉的服務(wù)下運(yùn)行，編輯配置文件，修改連接地址以下為修改后的顯示結(jié)果，是的服務(wù)，從可以看到下運(yùn)行

????關(guān)于postgres-xl的實(shí)驗(yàn)是在我自己筆記本rhel7.2_x64的環(huán)境下，用kvm實(shí)現(xiàn)的，總共有6臺(tái)虛擬機(jī)：

????一臺(tái)openfiler2.99發(fā)布共享存儲(chǔ)，一臺(tái)gtm master，一臺(tái)gtm slave，三臺(tái)gtm_proxy/coordinator/datanode，除了openfiler之外其余5臺(tái)虛擬機(jī)皆以最小化安裝rhel7.2_x64初始化，且具備兩張網(wǎng)卡，一張用于192.168.122.* 提供服務(wù)，一張用于10.10.10.* 讀取openfiler發(fā)布的共享存儲(chǔ)，具體的postgres-xl服務(wù)規(guī)劃如下。

服務(wù)名稱	服務(wù)作用	ip	服務(wù)端口	服務(wù)目錄	pooler port
gtm_mast	gtm master	192.168.122.179	20001	/pgdata/gtm/data
gtm_slav	gtm slave	192.168.122.189	20001	/pgdata/gtm/data
gtm_pxy01	gtm proxy	192.168.122.171	20001	/pgdata/gtm_pxy01/data
gtm_pxy02	gtm proxy	192.168.122.172	20001	/pgdata/gtm_pxy02/data
gtm_pxy03	gtm proxy	192.168.122.173	20001	/pgdata/gtm_pxy03/data
coord01	coordinator	192.168.122.171	15432	/pgdata/coord01/data	40101
coord02	coordinator	192.168.122.172	15432	/pgdata/coord02/data	40102
coord03	coordinator	192.168.122.173	15432	/pgdata/coord03/data	40103
datan01	datanode	192.168.122.181	25431	/pgdata/datan01/data	40401
datan02	datanode	192.168.122.182	25432	/pgdata/datan02/data	40402
datan03	datanode	192.168.122.183	25433	/pgdata/datan03/data	40403

一. 虛擬機(jī)操作系統(tǒng)配置 1. 主機(jī)名配置

對(duì)每個(gè)虛擬機(jī)修改主機(jī)名

hostnamectl set-hostname rhel7pg171

將 /etc/hosts 文件修改成格式化文件（帶域名就三列，不帶域名則兩列就行）

從 /etc/hosts 文件可以看出每臺(tái)虛擬機(jī)的主機(jī)名為 rhel7pgxxx

# cat /etc/hosts
127.0.0.1              localhost
192.168.122.1          station90
192.168.122.170        rhel7pg170
192.168.122.171        rhel7pg171
192.168.122.172        rhel7pg172
192.168.122.173        rhel7pg173
192.168.122.179        rhel7pg179
192.168.122.189        rhel7pg189
192.168.122.100        openfiler100
192.168.122.181        datan01
192.168.122.182        datan02
192.168.122.183        datan03

2. 安全設(shè)置

對(duì)每個(gè)虛擬機(jī)關(guān)閉selinux，關(guān)閉防火墻

setenforce 0
sed -i.bak "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config
systemctl disable firewalld.service
systemctl stop firewalld.service
iptables --flush

3. 本地yum服務(wù)配置

掛載本地cdrom中的操作系統(tǒng)ISO到本地目錄

mkdir -p /mnt/iso
mount /dev/cdrom /mnt/iso
# 寫入fstab，下次重起操作系統(tǒng)的時(shí)候自動(dòng)掛載
echo "/dev/cdrom    /mnt/iso    iso9660    defaults    0 0" >> /etc/fstab

創(chuàng)建本地yum源

vi /etc/yum.repos.d/base.repo
cat /etc/yum.repos.d/base.repo
[rhel7]
name=rhel7
baseurl=file:///mnt/iso
gpgcheck=0

[rhel7-HA]
name=rhel7-HA
baseurl=file:///mnt/iso/addons/HighAvailability
gpgcheck=0

[rhel7-RS]
name=rhel7-RS
baseurl=file:///mnt/iso/addons/ResilientStorage

更新yum服務(wù)信息

yum clean all
yum list
yum group list

4. 時(shí)間同步服務(wù)配置

安裝chrony包

yum install chrony.x86_64 -y

編輯配置文件，注釋掉默認(rèn)的server，添加已知可用的或者自建的時(shí)間服務(wù)器，本實(shí)驗(yàn)在openfiler的虛擬機(jī)192.168.122.100通過(guò)ntp發(fā)布了一個(gè)時(shí)間同步源

vi /etc/chrony.conf
# server 0.rhel.pool.ntp.org iburst
# server 1.rhel.pool.ntp.org iburst
# server 2.rhel.pool.ntp.org iburst
# server 3.rhel.pool.ntp.org iburst
server 192.168.122.100 iburst

重啟時(shí)間同步服務(wù)：

systemctl restart chronyd.service

查看時(shí)間同步狀態(tài)：

systemctl status chronyd.service

設(shè)置開(kāi)機(jī)啟動(dòng)服務(wù)：

systemctl enable chronyd.service

查看時(shí)間同步源：

chronyc sources -v

查看時(shí)間同步源狀態(tài)：

chronyc sourcestats -v

5. 重啟

重啟所有虛擬機(jī)，生效主機(jī)名和selinux的配置

init 6

二. postgres-xl軟件安裝 1. 依賴包的安裝

各種依賴包：

yum install -y make mpfr libmpc cpp kernel-headers glibc-headers glibc-devel libgomp libstdc++-devel libquadmath libgfortran libgnat libgnat-devel libobjc gcc gcc-c++ libquadmath-devel gcc-gfortran gcc-gnat gcc-objc gcc-objc++ ncurses-devel readline readline-devel zlib-devel m4 flex bison mailcap

perl的支持：

yum install -y perl 
perl-Carp 
perl-constant 
perl-Encode 
perl-Exporter 
perl-File-Path 
perl-File-Temp 
perl-Filter 
perl-Getopt-Long 
perl-HTTP-Tiny 
perl-libs 
perl-macros 
perl-parent 
perl-PathTools 
perl-Pod-Escapes 
perl-podlators 
perl-Pod-Perldoc 
perl-Pod-Simple 
perl-Pod-Usage 
perl-Scalar-List-Utils 
perl-Socket 
perl-Storable 
perl-Text-ParseWords 
perl-threads 
perl-threads-shared 
perl-Time-HiRes 
perl-Time-Local

2. postgres-xl主體的安裝

gunzip postgres-xl-9.5r1.4.tar.gz
tar -xvf postgres-xl-9.5r1.4.tar
cd postgres-xl-9.5r1.4
./configure
gmake
gmake install

3. pgxc_ctl插件的安裝

pgxc_ctl插件中，假如我們有需要配置備份配置文件的選項(xiàng)的話，需要修改下源代碼。postgres-xl-9.5r1.4/contrib/pgxc_ctl源代碼中do_command.c的static void init_all(void) 下面第二行，即第524行的init_gtm_master(true);前面，必須插入一行doConfigBackup();再保存編譯make&make install ，要不然用pgxc_ctl init all的時(shí)候，configBackup=y的功能沒(méi)辦法正常使用

cd postgres-xl-9.5r1.4/contrib/pgxc_ctl
vi do_command.c
make
make install

4. 用戶環(huán)境配置

此處環(huán)境變量要寫入 .bashrc 中，因?yàn)閜gxc_ctl會(huì)通過(guò)ssh信任協(xié)議直接遠(yuǎn)程到服務(wù)器上運(yùn)行命令，這樣的話不會(huì)去讀取.bash_profile，只會(huì)讀取.bashrc，如果不把PATH等環(huán)境變量配置到.bashrc的化，之后初始化集群init all 的時(shí)候就會(huì)報(bào)“命令不存在”的錯(cuò)誤。

/usr/sbin/groupadd -g 2001 postgres 
/usr/sbin/useradd -u 2001 -g postgres postgres 
echo "postgres_passwd" | passwd --stdin postgres
echo "export PGHOME=/usr/local/pgsql" >> /home/postgres/.bashrc
echo "export LD_LIBRARY_PATH==$PGHOME/lib" >> /home/postgres/.bashrc
echo "export PG_CONFIG=$PGHOME/bin/pg_config" >> /home/postgres/.bashrc
echo "export pg_config=$PGHOME/bin/pg_config" >> /home/postgres/.bashrc
echo "export PATH=$PATH:$PGHOME/bin" >> /home/postgres/.bashrc

5. 鏈接庫(kù)文件

source /home/postgres/.bash_profile
echo "$PGHOME/lib" >> /etc/ld.so.conf
/sbin/ldconfig
cat /etc/ld.so.conf

三. postgres-xl初始化 1. ssh互信配置

配置每個(gè)節(jié)點(diǎn)的postgres用戶互信
ssh互信配置方法非常多，可以參考《配置SSH互信》
http://blog.163.com/cao_jfeng...
我使用的是oracle的腳本

./sshUserSetup.sh -hosts "rhel7pg171 rhel7pg172 rhel7pg173 rhel7pg179 rhel7pg189" -user postgres -advanced -noPromptPassphrase -exverify

測(cè)試ssh互通

2. 創(chuàng)建PGDATA目錄

3臺(tái)datanode

mkdir -p /pgdata/datan01
mkdir -p /pgdata/datan02
mkdir -p /pgdata/datan03
mkdir -p /pgdata/coord01
mkdir -p /pgdata/coord02
mkdir -p /pgdata/coord03
mkdir -p /pgdata/gtm_pxy01
mkdir -p /pgdata/gtm_pxy02
mkdir -p /pgdata/gtm_pxy03

gtm master和gtm slave

mkdir -p /pgdata/gtm

所有節(jié)點(diǎn)

chown -R postgres:postgres /pgdata

3. datanode的特殊準(zhǔn)備

用openfiler配置3個(gè)3GB的共享磁盤給datan01 datan02 datan03
在datan01 datan02 datan03上執(zhí)行

systemctl enable iscsi
iscsiadm -m discovery -t sendtargets -p 10.10.10.100
iscsiadm -m node -T iqn.2006-01.com.openfiler:tsn.bf1f466b7eef -p 10.10.10.100 -l

在其中某個(gè)datanode上對(duì)共享磁盤進(jìn)行分區(qū)，分成一個(gè)分區(qū)即可，并對(duì)其進(jìn)行格式化

fdisk /dev/sda
fdisk /dev/sdb
fdisk /dev/sdc
partprobe /dev/sda
partprobe /dev/sdb
partprobe /dev/sdc
mkfs.xfs /dev/sda1
mkfs.xfs /dev/sdb1
mkfs.xfs /dev/sdc1
tune2fs -c 0 -i 0 /dev/sda1
tune2fs -c 0 -i 0 /dev/sdb1
tune2fs -c 0 -i 0 /dev/sdc1

重啟所有datanode進(jìn)行重新識(shí)別

掛載測(cè)試

mount /dev/sda1 /pgdata/datan01/
mount /dev/sdb1 /pgdata/datan02/
mount /dev/sdc1 /pgdata/datan03/
umount  /dev/sda1
umount  /dev/sdb1
umount  /dev/sdc1

添加每個(gè)datanode的臨時(shí)ip和掛載文件系統(tǒng)

cd /etc/sysconfig/network-scripts/
cp -rp ifcfg-eth0 ifcfg-eth0:1
vi ifcfg-eth0:1
systemctl restart network
mount /dev/sdc1 /pgdata/datan03/

所有節(jié)點(diǎn)

chown -R postgres:postgres /pgdata

4. pgxc_ctl配置文件編寫

進(jìn)入gtm_mast

su - postgres
pgxc_ctl
PGXC prepare
PGXC q
cd pgxc_ctl
vi pgxc_ctl.conf

編輯好的配置文件如下：

    #!/usr/bin/env bash
    #
    # Postgres-XC Configuration file for pgxc_ctl utility. 
    #
    # Configuration file can be specified as -c option from pgxc_ctl command.   Default is
    # $PGXC_CTL_HOME/pgxc_ctl.org.
    #
    # This is bash script so you can make any addition for your convenience to configure
    # your Postgres-XC cluster.
    #
    # Please understand that pgxc_ctl provides only a subset of configuration which pgxc_ctl
    # provide.  Here"s several several assumptions/restrictions pgxc_ctl depends on.
    #
    # 1) All the resources of pgxc nodes has to be owned by the same user.   Same user means
    #    user with the same user name.  User ID may be different from server to server.
    #    This must be specified as a variable $pgxcOwner.
    #
    # 2) All the servers must be reacheable via ssh without password.   It is highly recommended
    #    to setup key-based authentication among all the servers.
    #
    # 3) All the databases in coordinator/datanode has at least one same superuser.  Pgxc_ctl
    #    uses this user to connect to coordinators and datanodes.   Again, no password should
    #    be used to connect.  You have many options to do this, pg_hba.conf, pg_ident.conf and
    #    others.  Pgxc_ctl provides a way to configure pg_hba.conf but not pg_ident.conf.   This
    #    will be implemented in the later releases.
    #
    # 4) Gtm master and slave can have different port to listen, while coordinator and datanode
    #    slave should be assigned the same port number as master.
    #
    # 5) Port nuber of a coordinator slave must be the same as its master.
    #
    # 6) Master and slave are connected using synchronous replication.  Asynchronous replication
    #    have slight (almost none) chance to bring total cluster into inconsistent state.
    #    This chance is very low and may be negligible.  Support of asynchronous replication
    #    may be supported in the later release.
    #
    # 7) Each coordinator and datanode can have only one slave each.  Cascaded replication and
    #    multiple slave are not supported in the current pgxc_ctl.
    #
    # 8) Killing nodes may end up with IPC resource leak, such as semafor and shared memory.
    #    Only listening port (socket) will be cleaned with clean command.
    #
    # 9) Backup and restore are not supported in pgxc_ctl at present.   This is a big task and
    #    may need considerable resource.
    #
    #========================================================================================
    #
    #
    # pgxcInstallDir variable is needed if you invoke "deploy" command from pgxc_ctl utility.
    # If don"t you don"t need this variable.

                            # both as linus user and database user.  This must be
                            # the super user of each coordinator and datanode.
    pgxcUser=$pgxcOwner        # OS user of Postgres-XC owner

    #---- GTM ------------------------------------------------------------------------------------
    
    # GTM is mandatory.  You must have at least (and only) one GTM master in your Postgres-XC cluster.
    # If GTM crashes and you need to reconfigure it, you can do it by pgxc_update_gtm command to update
    # GTM master with others.   Of course, we provide pgxc_remove_gtm command to remove it.  This command
    # will not stop the current GTM.  It is up to the operator.

    #---- GTM Proxy -------------------------------------------------------------------------------------------------------
    # GTM proxy will be selected based upon which server each component runs on.
    # When fails over to the slave, the slave inherits its master"s gtm proxy.  It should be
    # reconfigured based upon the new location.
    #
    # To do so, slave should be restarted.   So pg_ctl promote -> (edit postgresql.conf and recovery.conf) -> pg_ctl restart
    #
    # You don"t have to configure GTM Proxy if you dont" configure GTM slave or you are happy if every component connects
    # to GTM Master directly.  If you configure GTL slave, you must configure GTM proxy too.
