编译安装openGauss并用GDB进行调试
关于编译opengauss,然后怎么去调试它,不知道花了多长时间.本来想着用类似Eclipse的IDE去编译调试源码,结果老是出现各种问题,不过好说歹说,现在可以通过GDB来进行调试,如果有哪位大佬会用IDE编译调试openGauss源码的话,请指教!!!
运行环境
Centos7.6(刚安装好的,啥也没有的那种)
内存8G
磁盘200G
omm用户的创建
首先创建一个omm用户和对应的用户组,创建两个文件夹.其中/opt/og文件夹用来存放源码文件和编译好的第三方库文件.而/opt/ogdata在数据库启动的时候会用到.
groupadd dbgrp -g 2000
useradd omm -g 2000 -u 2000
passwd omm
mkdir -p {/opt/og,/opt/ogdata}

passwd omm的時候会让你输入一个密码,随便输个1就行.
安装依赖
直接复制里面的代码然后在/opt/og/文件夹下执行就可以了,安装依赖的过程中可能需要让你确认一下.
PS:如果这里/opt/og不让操作,可以把后面步骤中 的赋权限操作在这里先执行一次,不过这里执行了以后后面还是要进行一次赋权限的操作.(这是因为后面git下载openGauss-server源码后这个文件夹的操作权限有问题,需要重新赋予)
yum install -y git
curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.rpm.sh | sudo bash
sudo yum install git-lfs
git lfs install
git clone https://gitee.com/opengauss/openGauss-server openGauss-server
yum install -y libaio-devel-0.3.109
yum install -y flex 2.5.37
yum install -y bison 2.7-4
yum install -y ncurses-devel 5.9-13.20130511
yum install -y glibc-devel 2.17-111
yum install -y patch 2.7.1-10
yum -y install redhat-lsb 4.1
yum install -y readline-devel 7.0-13

解压opengauss官网已经编译好的第三方库文件,然后修改gcc链接,下载python3.6并修改链接.修改完成后可以用gcc -v和 python --version看看修改成功没有.
tar -zxvf openGauss-third_party_binarylibs.tar.gz
mv openGauss-third_party_binarylibs binarylibs
cd binarylibs/buildtools/centos7.6_x86_64/gcc7.3/gcc/bin
rm -rf /usr/bin/gcc
ln -s /opt/og/binarylibs/buildtools/centos7.6_x86_64/gcc7.3/gcc/bin/gcc /usr/bin/gcc
yum install -y python3.6*
rm -rf /usr/bin/python
mv /usr/bin/python3.6 /usr/bin/python

python3.6安装完成后还需要修改下两个文件的文件头.
分别执行vi /usr/libexec/urlgrabber-ext-down和vi /usr/bin/yum,将这两个文件的第一行:#!/usr/bin/python修改为#!/usr/bin/python2.7 即可
文件夹赋权限
执行下面的语句给之前创建的文件夹赋予权限,然后su - omm切换到omm用户
chown -R omm: {/opt/og,/opt/ogdata}
chmod -R 755 /opt/og
chmod -R 700 /opt/ogdata
su - omm

设置环境变量
vi ~/.bashrc
1
把下面的内容复制进去:
export CODE_BASE=/opt/og/openGauss-server
export BINARYLIBS=/opt/og/binarylibs
export GAUSSHOME=$CODE_BASE/dest/
export GCC_PATH=$BINARYLIBS/buildtools/centos7.6_x86_64/gcc7.3
export CC=$GCC_PATH/gcc/bin/gcc
export CXX=$GCC_PATH/gcc/bin/g++
export LD_LIBRARY_PATH=$GAUSSHOME/lib:$GCC_PATH/gcc/lib64:$GCC_PATH/isl/lib:$GCC_PATH/mpc/lib/:$GCC_PATH/mpfr/lib/:$GCC_PATH/gmp/lib/:$LD_LIBRARY_PATH
export PATH=$GAUSSHOME/bin:$GCC_PATH/gcc/bin:$PATH

configure
直接复制然后执行即可.
source ~/.bashrc
cd /opt/og/openGauss-server/
./configure --gcc-version=7.3.0 CC=g++ CFLAGS='-O0' --prefix=$GAUSSHOME --3rd=$BINARYLIBS --enable-debug --enable-cassert --enable-thread-safety --without-readline --without-zlib

make and make install
不要用官方的make -sj.这命令老是把我虚拟机撑爆(8G内存). make -sj4好像也可以.不过我最后用的是make -j4.
make -j4
make install

初始化数据库
这里就用到了/opt/ogdata/ ,文件夹里面是空的.
gs_initdb --pgdata=/opt/ogdata/ --nodename=dn_6001 --encoding=utf-8
1
完成后大概会输出下面一段内容:
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 gs_initdb.
Success. You can now start the database server of single node using:
gaussdb -D /opt/ogdata --single_node
or
gs_ctl start -D /opt/ogdata -Z single_node -l logfile

启动数据库
直接用上面提示给出的命令启动数据库即可.第一次执行这条命令会失败.
gs_ctl start -D /opt/ogdata -Z single_node -l logfile
1
第一次启动失败之后执行下面一条语句重启一下就行了。
或者直接重启一下虚拟机,然后再执行一次上面的gs_ctl start -D /opt/ogdata -Z single_node -l logfile命令
gs_ctl restart -D /opt/ogdata -Z single_node -l logfile
1
连接数据库
启动完成后用如下命令进行数据库连接,端口默认是5432.
gsql -d postgres -p 5432
1
到这里为止整个数据库就算弄完了.然后就是通过gdb去调试opengauss了.首先gdb -v查看虚拟机上有没有gdb,没有的话需要安装一个.
GDB调试
[omm@localhost ~]$ gdb -v

然后输入以下命令找一下GDB连接需要的ID
netstat -anp|grep gaussdb
1
大概会输出以下内容,注意找5432端口对应的.这里就是第一行的最后 20220/gaussdb的 20220.

gdb命令开始调试
首先输入gdb进入gdb环境,然后输入attach 20220连接数据库开始进行调试.
这里你再连接数据库的话就会发现请求被阻塞住了.然后输入bt可以看到当前的函数调用栈.输入n可以执行下一步等等.具体的GDB有哪些命令就不多说了,可以找一些详细的文档看一下.这里给一个参考链接,如果感觉不全可以在找找其他的
