chmod +x postgresql-9.5.5-1-linux-x64.run
./postgresql-9.5.5-1-linux-x64.run
</pre>
按照提示的信息安装并创建完成数据库
第二步，安装[libsnappy],libsnapp可以通过yum进行安装；也可以到 wget https://github.com/google/snappy/tarball/master下载源码
<pre>
yum install snappy
yum install snappy-devel
</pre>
第三步，安装avro-c
<pre>
wget http://apache.fayea.com/avro/avro-1.8.1/c/avro-c-1.8.1.tar.gz
tar -zxvf avro-c-1.8.1.tar.gz
cd avro-c-1.8.1/
mkdir build
cd build/
cmake .. -DCMAKE_INSTALL_PREFIX=$PREFIX -DCMAKE_BUILD_TYPE=RelWithDebInfo
提示cmake不存在，通过yum安装了cmake
yum install cmake
</pre>
再次执行cmake .. -DCMAKE_INSTALL_PREFIX=$PREFIX -DCMAKE_BUILD_TYPE=RelWithDebInfo
<pre>
[root@gp-node2 build]# cmake .. -DCMAKE_INSTALL_PREFIX=$PREFIX -DCMAKE_BUILD_TYPE=RelWithDebInfo
Enabled deflate codec
-- Found Snappy: /lib64/libsnappy.so

到此，安装完成，后续开始进行配置
============================================================================================
1、修改postges的设置，修改postgresql.conf文件在的如下几个选项：
wal_level = logical
max_wal_senders = 8
wal_keep_segments = 4
max_replication_slots = 4
修改pg_hba.conf，增加同步的账户
host replication repuser 0.0.0.0/0 md5
重启postgres服务
2、创建账号,创建扩展
<pre>
-bash-4.2$ psql
Password:
psql.bin (9.5.5)
Type "help" for help.
postgres=#
postgres=# CREATE ROLE repuser REPLICATION LOGIN PASSWORD 'repuser';
postgres=# create extension bottledwater;
CREATE EXTENSION
</pre>
