-## set_mariadb_param_info.sh
+## get_mariadb_param_info.sh
 该脚本在mariadb_server.yaml中使用，获取测试机1中mariadb相关的参数值,用来进行本地调优。（因为两台测试机硬件规格和环境比较相似，因此用使用第一个测试机的数据来进行调优即可）
 如果需要扩展为不同机器的mariadb下发参数不同，可以扩展该脚本为两个参数，指定IP和参数名，用于给对应机器的参数进行下发。

+# values can be found in the PostgreSQL documentation.
+#
+# The commented-out settings shown in this file represent the default values.
+# Re-commenting a setting is NOT sufficient to revert it to the default value;
+# you need to reload the server.
+#
+# This file is read on server startup and when the server receives a SIGHUP
+# signal.  If you edit the file on a running system, you have to SIGHUP the
+# server for the changes to take effect, run "pg_ctl reload", or execute
+# "SELECT pg_reload_conf()".  Some parameters, which are marked below,
+# require a server shutdown and restart to take effect.
+#
+# Any parameter can also be given as a command-line option to the server, e.g.,
+# "postgres -c log_connections=on".  Some parameters can be changed at run time
+# with the "SET" SQL command.

+# 1.环境准备
+物理机和虚拟机协同调优，同时采集虚拟机的系统参数、应用参数和物理机的应用参数。
+## 1.1 虚拟机上操作
+### 1.1.1 安装postgresql数据库
+在虚拟机上操作
+后续对sysbench编译时会用到postgresql的动态库文件和头文件
+```bash
+yum install postgresql-server postgresql-devel -y
+```
+### 1.1.2 初始化数据库集群
+在虚拟机上初始化数据库
+```bash
+/usr/bin/postgresql-setup --initdb
+```
+### 1.1.3 修改监听端口
+在虚拟机机上，修改postgresql的配置文件 /var/lib/pgsql/data/postgresql.conf ，修改第60行，去掉注释并将监听端口改为'*'，表示监听所有的ip：
+
+```bash
+listen_addresses = '*'
+```
+### 1.1.4 配置数据库免密和远程连接
+在虚拟机上，修改postgresql的配置文件 /var/lib/pgsql/data/pg_hba.conf ，配置本地免密连接，确保和如下配置相同，即trust：
+```bash
+local   all             all                                     trust
+```
+在虚拟机上，修改postgresql的配置文件 /var/lib/pgsql/data/pg_hba.conf ，在最后一行添加如下内容，允许远程机器免密登录：
+```bash
+host    all             all             0.0.0.0/0               trust
+```
+### 1.1.5 设置防火墙
+在虚拟机上，开放端口5432，该端口是postgresql的默认端口：
+```bash
+firewall-cmd --zone=public --add-port=5432/tcp --permanent
+firewall-cmd --reload
+```
+### 1.1.6 重启服务使配置文件生效
+在虚拟机上，重启postgresql服务
+```bash
+systemctl restart postgresql
+```
+### 1.1.7 创建数据库sbtest
+在虚拟机上操作，要配置免密登录
+登录默认数据库postgres
+```bash
+psql -U postgres -d postgres   
+```
+创建数据库sbtest
+```bash
+CREATE DATABASE sbtest;
+```
+查看有哪些数据库
+```bash
+\l
+```
+退出数据库
+```bash
+\q
+```
+验证sbtest数据库是否创建成功，连接新创建的数据库sbtest
+```bash
+psql -U postgres -d sbtest
+```
+
+
+### 1.1.8 配置虚拟机和物理机之间的免密
+
+虚拟机上执行，生成密钥，执行此命令后按Enter键可以全部采用默认的配置：
+```bash
+ssh-keygen
+```
+虚拟机上执行，将公钥分发到物理机节点，9.82.190.218为物理机ip，分发公钥过程中需要输入相应物理机的密码：
+```bash
+ssh-copy-id root@9.82.190.218
+```
+虚拟机上执行，验证免密登录，远程登录物理机9.82.190.218（登录后可以用exit退出）：
+```bash
+ssh root@9.82.190.218
+```
+## 1.2 部署A-Tune环境
+在虚拟机上执行
+具体安装启动方式参考A-Tune README-zh 文档第一节“安装A-Tune”,A-Tune仓库链接：https://gitee.com/openeuler/A-Tune
+
+```bash
+yum install -y atune atune-engine
+```
+加载并启动atuned和atune-engine服务:
+```bash
+systemctl start atuned
+systemctl start atune-engine
+```
+下载A-Tune源码，具体操作如下
+```bash
+cd /home
+git clone https://gitee.com/openeuler/A-Tune.git
+```
+进入目录A-Tune/examples/tuning/postgresql,
+```bash
+cd A-Tune/examples/tuning/postgresql
+```
+# 2.调优环境准备
+## 2.1 运行环境准备
+在虚拟机上执行
+进入A-Tune/examples/tuning/postgresql目录下，运行prepare.sh脚本来替换调优文件中的路径，执行后还需输入远程物理机的ip：
+```bash
+sh prepare.sh
+```
+物理机为ip为server_ip，执行结果如下：
+```shell
+[root@openEuler postgresql]# sh prepare.sh 
+[INPUT] enter server_ip of sysbench to used:9.82.190.218
+[INFO] update path for postgresql files
+[INFO] update ip for postgresql files
+```
+
+## 2.2 运行benchmark脚本（可选）
+在虚拟机上运行 A-Tune/examples/tuning/postgresql/postgresql_sysbench_benchmark.sh ，该脚本执行成功证明sysbench测试可以正常运行：
+```bash
+sh postgresql_sysbench_benchmark.sh
+```
+
+## 2.3 atune调优
+atune-adm tuning 是 A-Tune 的调优命令，它会根据postgresql_sysbench_client.yaml中的配置文件对postgresql数据库进行调优。会根据环境和性能数据自动选择合适的调优策略，优化集群的性能。调优过程中，可以通过查看A-Tune/examples/tuning/postgresql/sysbench_oltp_read_write.log日志来确定服务是否正常执行：
+```bash
+atune-adm tuning --project postgresql --detail postgresql_sysbench_client.yaml
+```
+
+执行调优命令后，会先执行sysbench获取基线数据，然后加载postgresql项目的调优配置文件，输出如下：
+第一轮输出：
+Best Performance: (QPS=23740.23), Performance Improvement Rate: 3.78%
+代表最优的性能指标，以及性能提升比例，对比基线是第一轮benchmark的结果。
+```bash
+[root@openEuler postgresql]# atune-adm tuning --project postgresql --detail postgresql_sysbench_client.yaml
+ Start to benchmark baseline...
+ 1.Loading its corresponding tuning project: postgresql
+ 2.Start to tuning the system......
+ Current Tuning Progress......(1/30)
+ Used time: 38s, Total Time: 38s, Best Performance: (QPS=23740.23), Performance Improvement Rate: 3.78%
+ The 1th recommand parameters is: kernel.numa_balancing=1,kernel.sched_autogroup_enabled=1,shared_buffers=66441,effective_cache_size=786432,work_mem=12288,max_parallel_workers=4,maintenance_work_mem=451584,cpu_tuple_cost=0.029,cpu_index_tuple_cost=0.003,effective_io_concurrency=2
+ The 1th evaluation value: (QPS=23740.23)(3.78%)
+```
+
+## 2.4 恢复原有的配置参数（可选）
+原始的参数配置文件为/var/atuned/postgresql-tuning-restore.conf。
+可以先执行如下命令恢复调优前的环境配置：
+```bash
+atune-adm tuning --restore --project postgresql
+```
+# 3.主要文件功能介绍
+## 3.1 get_postgresql_param_info.sh
+该脚本在postgresql_sysbench_client.yaml中使用，获取postgresql数据库相关的参数值,用来进行本地调优。
+如果需要扩展为不同机器的postgresql下发参数不同，可以扩展该脚本为两个参数，指定IP和参数名，用于给对应机器的参数进行下发。
+```bash
+#!/bin/bash
+
+# 检查是否传入参数
+if [ -z "$1" ]; then
+  echo "请提供一个参数"
+  exit 1
+fi
+
+# 获取传入的参数
+param=$1
+
+cat /var/lib/pgsql/data/postgresql.conf | grep '^$param' | awk -F '=' '{print \$2}'
+```
+## 3.2 set_postgresql_param_info.sh
+该脚本用于下发参数到postgresql节点。
+若需要多台机器设置不同的值此脚本需额外扩展一个参数IP用于指定对应机器进行参数下发。
+```bash
+#!/bin/bash
+
+# 检查是否传入参数
+if [ -z "$1" ]; then
+  echo "请提供一个参数"
+  exit 1
+fi
+
+# 获取传入的参数
+param=$1
+value=$2
+
+sed -i 's/^$param.*$/$param=$value/g' /var/lib/pgsql/data/postgresql.conf
+```
+## 3.3 postgresql_sysbench_benchmark.sh
+该脚本是sysbench执行脚本，执行性能压测并汇总结果到虚拟机上。该脚本会将测试结果输出到sysbench_oltp_read_write.log文件，最终通过get_eval.sh脚本获得queries指标并反馈给atune。
+```bash
+#!/bin/sh
+
+TABLES=50
+TABLE_SIZE=20000
+
+while true
+do
+    sysbench --config-file=sysbench_config.cfg oltp_read_write --tables=$TABLES --table-size=$TABLE_SIZE --time=30 prepare
+    ret=$?
+    if [ $ret == 0 ];then
+        break
+    fi
+done
+
+sysbench --config-file=sysbench_config.cfg oltp_read_write --tables=$TABLES --table-size=$TABLE_SIZE --time=100 run  > PATH/sysbench_oltp_read_write.log
+count=0
+while true
+do
+    val=$(cat PATH/sysbench_oltp_read_write.log  | grep 'queries:' | awk -F '(' '{print $2}' | awk -F ' ' '{print $1}')
+    if [ $val != "" ];then
+        break
+    elif [ $count == 10 ];then
+        break
+    else
+        count=$(($count+1))
+        sleep 3
+    fi
+done
+
+sysbench --config-file=sysbench_config.cfg oltp_read_write --tables=$TABLES --table-size=$TABLE_SIZE  cleanup
+```
+## 3.4 get_eval.sh
+该脚本是调优指标获取脚本，通过匹配sysbench测试日志中的固定字段queries来获取调优指标的值，供atune调优使用。
+```bash
+#!/bin/bash
+i=1
+while [ $i -lt 10 ]
+do
+        sleep $i
+        if [ -f "PATH/sysbench_oltp_read_write.log" ] && [ -n "$(cat PATH/sysbench_oltp_read_write.log  | grep 'queries:' | awk -F '(' '{print $2}' | awk -F ' ' '{print $1}')" ]; then
+                cat PATH/sysbench_oltp_read_write.log  | grep 'queries:' | awk -F '(' '{print $2}' | awk -F ' ' '{print $1}'
+                break
+        fi
+        i=$((i+1))
+done
+```
