1.Install PostgreSql9.3
a:yum install
copy repository to: /etc/yum/yum.repos.d
yum -y install postgresql93-server postgresql93-contrib --skip-broken
yum install http://yum.postgresql.org/9.5/redhat/rhel-7-x86_64/pgdg-redhat95-9.5-2.noarch.rpm
sudo yum install postgresql95-server postgresql95-contrib
2.Install postgres
yum -y install postgresql93-server postgresql93-contrib3.Master 配置1.创建PG Data Dirmkdir –p /opt/PostgreSQL/data mkdir –p /opt/PostgreSQL/data/archive chmod 700 /opt/PostgreSQL/data sudo chown postgres:postgres /opt/PostgreSQL/data
2.设置profile
sudo vi /etc/profile export PATH=/usr/pgsql-9.3/bin:$PATH export PGDATA=/opt/PostgreSQL/data/ su – postgres vi ~/.bash_profile export PATH=/usr/pgsql-9.3/bin:$PATH export PGDATA=/opt/PostgreSQL/data/
3.InitDB For master
su -postgres initdb --encoding=UTF-8 --username=postgres --pwprompt --pgdata=/opt/PostgreSQL/data/
4.配置文件

vi $PGDATA_HOME/postgresql.conf
listen_addresses = ‘*‘
port = 5432
wal_level = hot_standby
max_wal_senders = 5
wal_keep_segments = 32
archive_mode = on
archive_command = ‘cp %p /opt/PostgreSQL/data/%f < /dev/null‘
checkpoint_segments = 8
5.启动Master DB
su -postgres pg_ctl -D /opt/PostgreSQL/data/ -l logfile start
pg_ctl –D /var/lib/pgsql/9.3/data -l logfile start psql -c "CREATE USER postgres REPLICATION LOGIN ENCRYPTED PASSWORD ‘conversant‘;"
$psql
postgres=# alter user postgres with password ‘conversant‘;
4.Slave4.1 Install Postgres4.2 Configure Profile4.3 Copy master datasu –postgres pg_basebackup -h 192.168.1.12 -D /opt/PostgreSQL/data -U replicator -P -v -x
4.4 配置
vi $PGDATA_HOME/postgresql.conf
listen_addresses = ‘*‘ hot_standby = on wal_level = hot_standby max_wal_senders = 3 wal_keep_segments = 8 checkpoint_segments = 8
vi $PGDATA_HOME/recovery.conf
sudo su - cp /usr/pgsql-9.3/share/recovery.conf.sample /opt/PostgreSQL/data/ chown postgres:postgres recovery.conf.sample mv recovery.conf.sample recovery.conf
vi recovery.conf primary_conninfo = ‘host=192.168.1.12 port=5432 user=replicator password=conversant‘ trigger_file = ‘/opt/PostgresSql/data/trigger‘ standby_mode = ‘on‘
5.打开防火墙 5432端口
$sudo /sbin/iptables -I INPUT -p tcp --dport 5432 –j ACCEPT
$sudo /etc/rc.d/init.d/iptables save
$sudo /etc/init.d/iptables status
6.启动Slave
su -postgres pg_ctl -D /opt/PostgreSQL/data/ -l logfile start
1. start pg_ctl -D /opt/PostgreSQL/data/ -l /opt/PostgreSQL/data/logfile start 2. stop pg_ctl -D /opt/PostgreSQL/data/ -l /opt/PostgreSQL/data/logfile --mode=fast stop 3. restart pg_ctl -D /opt/PostgreSQL/data/ -l /opt/PostgreSQL/data/logfile restart
