1、编译安装
yum install -y gcc gcc-c++ automake autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers bison* glib* flex readline readline-devel apr apr-util apr-develrzsz sysstat e4fsprogs ntp readline-devel openssl openssl-devel pam-devel libxml2-devel libxslt-devel python-devel tcl-devel flex bison
tar –jxvf postgresql-9.2.1.tar.bz2 cd postgresql-9.2.1 ./configure --prefix=/usr/local/pgsql gmake world gmake install-world
2、新建用户,授权
#创建数据库目录 mkdir /data #创建用户 postgres ,并授权 useradd postgres chown postgres.postgres /data
3、配置环境变量
#切换到 postgres 用户 su postgres #为其配置环境变量: vim ~postgres/.bash_profile PGLIB=/usr/local/pgsql/lib PGDATA=/data PATH=$PATH:/usr/local/pgsql/bin MANPATH=$MANPATH:/usr/local/pgsql/man export PGLIB PGDATA PATH MANPATH export PGDATA=/data
4、初始化数据库
initdb -D $PGDATA
5、Master 配置文件修改
vim pg_hba.conf
host all all 192.168.2.4/32 trust
host all postgres 192.168.2.4/32 trust
vim postgres.conf listen_addresses=‘*‘ wal_level = ‘hot_standby‘ max_wal_senders = 3 wal_keep_segments = 16 # 80 GB required on pg_xlog cp /usr/local/pgsql/share/recovery.conf.sample /data/recovery.cone vim reconver.conf standby_mode = on primary_conninfo = ‘host=master port=5433 user=postgres‘ #从节点信息
6、生成备库实例
[postgres@localhost data]$pg_ctl –D $PGDATA -p 5432
传送数据文件到slave
在备库执行
[postgres@localhost data]$pg_basebackup -D $PGDATA -Fp -Xs -v -h master -p 5432 -U postgres
7、Slave 配置文件修改
[postgres@localhost data]$ vim postgresql.conf
注意删除 "#"
hot_standby = on vim reconver.conf standby_mode = on primary_conninfo = ‘host=master port=5432 user=postgres‘ #主节点信息
8、启动主从数据库
pg_ctl –D $PGDATA
master
[postgres@localhost data]$ ps -ef |grep postgres |grep sender postgres 12021 10924 0 14:37 ? 00:00:00 postgres: wal sender process postgres 172.16.0.132(33427) streaming 0/3036838
slave
[postgres@localhost data]$ ps -ef |grep postgres |grep recover postgres 5479 5471 0 17:24 ? 00:00:00 postgres: startup process recovering 00000002000000000000000D
注意:这个时候slave从master同步数据,但是slave 是只读的。
