Linux安装postgresql

官网下载压缩包，地址:下载

1. 将下载好的压缩包放至服务器，解压

tar -zxvf postgresql

2. 进入解压后的文件夹

cd postgresql

3. 运行configure

./configure

如果这一步报了这个错，说明系统已经安装了readline包
configure: error: readline library not found
If you have readline already installed, see config.log for details on the
failure. It is possible the compiler isn’t looking in the proper directory.
Use --without-readline to disable readline support.
 
可以运行一下这个命令，看看是不是这个包的问题
yum -y install -y readline-devel

重新 ./configure

又出现了一个类似的错误
configure: error: zlib library not found
If you have zlib already installed, see config.log for details on the
failure. It is possible the compiler isn’t looking in the proper directory.
Use --without-zlib to disable zlib support.
 
运行下面的命令
yum install zlib-devel

再来一次 ./configure
成功。

make

make install

6. 配置环境变量

#配置环境变量前先创建一个文件夹
mkdir /usr/local/pgsql/data

vim ~/.bash_profile

#写入以下配置
export PGHOME=/usr/local/pgsql
export PGDATA=/usr/local/pgsql/data 

7. 保存退出后执行命令，使配置生效

source ~/.bash_profile

8. 创建一个普通用户
9. 然后依次执行以下命令

chown postgres /usr/local/pgsql/data

su - postgres

/usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data

/usr/local/pgsql/bin/postgres -D /usr/local/pgsql/data >logfile 2>&1 &

cd usr/local/pgsql/bin   

./pg_ctl start

#如果需要修改端口号，在安装目录的bin文件夹内，
vim postgresql.conf
