postgresql9.5 run 文件linux安装后配置成开机服务

网上出现的比较多安装方法要么是源码安装，要么是yum安装，我发觉都要配置很多属性，比较麻烦，所以现在我在centos7长用 run文件来安装

http://get.enterprisedb.com/postgresql/postgresql-9.5.1-1-linux-x64.run

这里的安装shell整理的很零乱，后面会整理一个完整版本的出来

wget https://pgbouncer.github.io/downloads/files/1.7.2/pgbouncer-1.7.2.tar.gz
wget http://get.enterprisedb.com/postgresql/postgresql-9.5.1-1-linux-x64.run
wget https://github.com/libevent/libevent/releases/download/release-2.0.22-stable/libevent-2.0.22-stable.tar.gz

tar zxvf libevent-2.0.22-stable.tar.gz
cd libevent-2.0.22-stable
./configure --prefix=/usr/local/libevent
make
make install
cd ..

tar zxvf pgbouncer-1.7.2.tar.gz
cd pgbouncer-1.7.2
./configure --prefix=/usr/local/pgbouncer/ --with-libevent=/usr/local/libevent/
make
make install
cd ..

chmod 777 postgresql-9.5.1-1-linux-x64.run
./postgresql-9.5.1-1-linux-x64.run

sudo chown -R postgres.postgres /alidata/pgsql
sudo chown -R postgres.postgres /usr/local/pgbouncer

#以下为配置环境变量部分，这里还没写好，你可以参考
su - postgres
cp .bash_profile /alidata/pgsql
cp .bashrc  /alidata/pgsql
su - postgres

export PGHOME=/alidata/pgsql
export PATH=$PGHOME/bin:$PATH
export PGDATA=$PGHOME/data
export LD_LIBRARY_PATH=$PGHOME/lib
export LD_LIBRARY_PATH=/usr/local/libevent/lib:$LD_LIBRARY_PATH

　　

用run文件安装就比较简单，但是安装完成后，它会默认安装成linux的系统服务，所以这里需要从源码里面去拷贝

PostgreSQL的开机自启动脚本位于PostgreSQL源码目录的contrib/start-scripts路径下

linux文件即为linux系统上的启动脚本

#chmod a+x linux

#cp linux /etc/init.d/postgresql

#修改/etc/init.d/postgresql文件的两个变量

prefix设置为postgresql的安装路径：/alidata/pgsql

附此文件，如果你没下载源码，可以直接通过在

vi postgresql新建一个文件

把下面这段拷贝进去保存

拷贝进去放到 /etc/init.d/下

然后service postgresql status 可以查询对应的操作

#! /bin/sh

# chkconfig: 2345 98 02
# description: PostgreSQL RDBMS

# This is an example of a start/stop script for SysV-style init, such
# as is used on Linux systems.  You should edit some of the variables
# and maybe the 'echo' commands.
#
# Place this file at /etc/init.d/postgresql (or
# /etc/rc.d/init.d/postgresql) and make symlinks to
#   /etc/rc.d/rc0.d/K02postgresql
#   /etc/rc.d/rc1.d/K02postgresql
#   /etc/rc.d/rc2.d/K02postgresql
#   /etc/rc.d/rc3.d/S98postgresql
#   /etc/rc.d/rc4.d/S98postgresql
#   /etc/rc.d/rc5.d/S98postgresql
# Or, if you have chkconfig, simply:
# chkconfig --add postgresql
#
# Proper init scripts on Linux systems normally require setting lock
# and pid files under /var/run as well as reacting to network
# settings, so you should treat this with care.

# Who to run the postmaster as, usually "postgres".  (NOT "root")
PGUSER=postgres

# Where to keep a log file
PGLOG="$PGDATA/serverlog"

# It's often a good idea to protect the postmaster from being killed by the
# OOM killer (which will tend to preferentially kill the postmaster because
# of the way it accounts for shared memory).  To do that, uncomment these
# three lines:
#PG_OOM_ADJUST_FILE=/proc/self/oom_score_adj
#PG_MASTER_OOM_SCORE_ADJ=-1000
#PG_CHILD_OOM_SCORE_ADJ=0
# Older Linux kernels may not have /proc/self/oom_score_adj, but instead
# /proc/self/oom_adj, which works similarly except for having a different
# range of scores.  For such a system, uncomment these three lines instead:
#PG_OOM_ADJUST_FILE=/proc/self/oom_adj
#PG_MASTER_OOM_SCORE_ADJ=-17
#PG_CHILD_OOM_SCORE_ADJ=0

chkconfig --add 服务名称          (首先，添加为系统服务,注意add前面有两个横杠)

chkconfig --leve 启动级别 服务名 on         

说明，3级别代表在命令行模式启动，5级别代表在图形界面启动，on表示开启）

 chkconfig --leve 启动级别 服务名 off              

（说明，off表示关闭自启动）

 例如：chkconfig --level 3 postgresql on                     (说明：让postgresql 服务在命令行模式，随系统启动)
