Pg安装 一、 建立用户, 这个用户随意,不必定非要叫postgres。 Useradd pumpkin ; 二、 下载pg源码安装包，目前我用的是9.3.5。 三、 源码安装pg [pumpkin@hl231 ~]$ ll 总用量 21436 -rw-r--r--. 1 pumpkin pumpkin 21946446 7月 25 2014 postgresql-9.3.5.tar.gz [pumpkin@hl231 ~]$ tar zxf postgresql-9.3.5.tar.gz -- 解压到当前目录 [pumpkin@hl231 ~]$ mkdir /home/pumpkin/pg9.3 -- 建立安装目录 [pumpkin@hl231 ~]$ ls -- 当前的目录结构 pg9.3 postgresql-9.3.5 postgresql-9.3.5.tar.gz [pumpkin@hl231 ~]$ cd postgresql-9.3.5 -- 切换进入解压目录 [pumpkin@hl231 postgresql-9.3.5]$ ./configure --prefix=/home/pumpkin/pg9.3/ --with-openssl -- 开始初始化并安装 checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu checking which template to use... linux checking whether to build with 64-bit integer date/time support... yes checking whether NLS is wanted... no checking for default port number... 5432 checking for block size... 8kB checking for segment size... 1GB checking for WAL block size... 8kB checking for WAL segment size... 16MB checking for gcc... gcc checking ….. 如下都省略了 太多了. [pumpkin@hl231 postgresql-9.3.5]$ make ….. [pumpkin@hl231 postgresql-9.3.5]$ make install … make[1]: Leaving directory `/home/pumpkin/postgresql-9.3.5/config' PostgreSQL installation complete. – 看到这些说明已经安装成功了 四、 配置一下环境变量 [pumpkin@hl231 ~]$ vim ~/.bash_profile PATH=$PATH:$HOME/bin PG_HOME=/home/pumpkin/pg9.3 export PG_HOME PG_DATA=/home/pumpkin/pgdata export PG_DATA PG_PORT=5434 export PG_PORT PATH=$PG_HOME/bin:$PATH export PATH [pumpkin@hl231 ~]$ source ~/.bash_profile -- 生效 五、 初始化pgdata [pumpkin@hl231 ~]$ mkdir ~/pgdata – 建立目录 [pumpkin@hl231 ~]$ initdb -D ~/pgdata/ --encoding=UTF8 --locale=C -- 初始化一个数据库实例 The files belonging to this database system will be owned by user "pumpkin". This user must also own the server process. The database cluster will be initialized with locale "C". The default text search configuration will be set to "english". Data page checksums are disabled. fixing permissions on existing directory /home/pumpkin/pgdata ... ok creating subdirectories ... ok selecting default max_connections ... 100 selecting default shared_buffers ... 128MB creating configuration files ... ok creating template1 database in /home/pumpkin/pgdata/base/1 ... ok initializing pg_authid ... ok initializing dependencies ... ok creating system views ... ok loading system objects' descriptions ... ok creating collations ... ok creating conversions ... ok creating dictionaries ... ok setting privileges on built-in objects ... ok creating information schema ... ok loading PL/pgSQL server-side language ... ok vacuuming database template1 ... ok copying template1 to template0 ... ok copying template1 to postgres ... ok syncing data to disk ... ok WARNING: enabling "trust" authentication for local connections You can change this by editing pg_hba.conf or using the option -A, or --auth-local and --auth-host, the next time you run initdb. Success. You can now start the database server using: postgres -D /home/pumpkin/pgdata/ or pg_ctl -D /home/pumpkin/pgdata/ -l logfile start - 初始化完成 初始化完毕以后修改几个参数： Postgresql.conf 中 修改 listen_addresses = '*' # what IP address(es) to listen on; # comma-separated list of addresses; # defaults to 'localhost'; use '*' for all # (change requires restart) port = 5434 # (change requires restart) pg_hba.conf 中按照本身的要求进行修改,本次只是用来进行演示，因此我就不改了。 六、 启动数据库 [pumpkin@hl231 ~]$ pg_ctl start -D ~/pgdata/ -- 启动数据库 server starting $[pumpkin@hl231 ~]$ psql -U postgres psql (9.3.5) Type "help" for help. postgres=# select version(); version -------------------------------------------------------------------------------- ------------------------------ PostgreSQL 9.3.5 on x86_64-unknown-linux-gnu, compiled by gcc (GCC) 4.4.7 20120 313 (Red Hat 4.4.7-4), 64-bit (1 row) postgres=# 到此数据库安装完毕 七、 八、
