PgSQL基础之 安装postgresql数据系统

参考这位仁兄的文章，真的非常好：https://blog.csdn.net/jerry_sc/article/details/76408116#创建数据目录

后来我又自己写了一个shell脚本，来自动化安装pgsql10.5版本。

#!/bin/bash
#进入软件的制定安装目录
echo "进入目录/usr/local，下载pgsql文件"
cd /usr/local
#判断是否有postgre版本的安装包
if [ -d post* ]
then
        rm -rf /usr/local/post*
        echo "安装包删除成功"
fi
#开始下载pgsql版本10.5并解压
if [ ! -d /usr/local/src ]
then
        mkdir /usr/local/src
fi
cd /usr/local/src
wget https://ftp.postgresql.org/pub/source/v10.5/postgresql-10.5.tar.gz
if [ $? == 0 ]
thentar -zxf postgresql-10.5.tar.gz -C /usr/local/
fi
echo "pgsql文件解压成功"
#判断用户是否存在
id $postgres >& /dev/null
echo "用户postgres已存在"
if [ $? -ne 0 ]
then
        echo "用户不存在，开始创建postgres用户"
        groupadd postgres
        useradd -g postgres postgres
fi
echo "重命名postgresql并且进入安装目录"
mv /usr/local/post* /usr/local/pgsql
cd /usr/local/pgsql
#-------------------------------安装pgsql------------------------------------
echo "安装一些库文件"
yum install -y zlib zlib-devel >& /del/null
echo "开始执行configure步骤"
./configure --prefix=/usr/local/pgsql --without-readline
if [ $? == 0 ]
then
        echo "configure配置通过，开始进行make编译"
        make
        if [ $? == 0 ]
        then
                echo "make编译通过，开始进行make install安装步骤"
                make install
                if [ $? != 0 ];then
                        echo "make install安装失败"
                fi
                echo "安装成功"
        else
                echo "make编译失败，检查错误。"
        fi
else
        echo "configure检查配置失败，请查看错误进行安装库文件"
fi
echo "开始进行pgsql的配置"
echo "给pgsql创建data目录"
mkdir -p /usr/local/pgsql/data
echo "修改用户组"
chown -R postgres:postgres /usr/local/pgsql
echo "添加环境变量,进入postgres用户的家目录"
cd /home/postgres
if [ -f .bash_profile ] ;then
        cp .bash_profile .bash_profile.bak
        echo "export PGHOME=/usr/local/pgsql" >> .bash_profile
        echo "export PGDATA=/usr/local/pgsql/data" >> .bash_profile
        echo "PATH=$PGHOME/bin:$PATH" >> .bash_profile
        echo "MANPATH=$PGHOME/share/man:$MANPATH" >> .bash_profile
        echo "LD_LIBRARY_PATH=$PGHOME/lib:$LD_LIBRARY_PATH" >> .bash_profile
fi
alias pg_start='pg_ctl -D $PGDATA -l /usr/local/pgsql/logfile start'
alias ps_stop='pg_ctl -D $PGDATA -l /usr/local/pgsql/logfile stop'
echo "切换至postgres用户来初始化数据库"
su - postgres -c "/usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data"
