TDengine3.0源代码编译安装

从官方文档来看 TDengine3.0 的编译方法和 TDengine2.0 没有什么区别, 2.0 的编译见《通过源代码编译安装TDengine》。

官方文档：https://github.com/taosdata/TDengine/blob/main/README.md

以下为编译安装步骤。

• 1.下载源代码
• 2.安装编译工具
• 3.安装依赖包
• 4.编译
• 5.安装（非必要）
• 6.运行

• 6.1.配置taos
• 6.2.运行服务端
• 6.3.运行客户端

1.下载源代码

git clone https://github.com/taosdata/TDengine.git

[root@c3-14 /]# git clone https://github.com/taosdata/TDengine.git

因为代码一直处于开发状态，最新的代码不一定能编译成功，选择一个发行分支是比较妥当的做法。

[root@c3-14 /]# cd TDengine/
[root@c3-14 TDengine]# git branch
* main
[root@c3-14 TDengine]# git branch -a | grep release | grep 3.0
  remotes/origin/chore/sangshuduo/release-script-add-comp-for-taostools-for3.0.2.2

[root@c3-14 TDengine]# git checkout release/ver-3.0.2.4
Branch release/ver-3.0.2.4 set up to track remote branch release/ver-3.0.2.4 from origin.
Switched to a new branch 'release/ver-3.0.2.4'
[root@c3-14 TDengine]# git branch
  main
* release/ver-3.0.2.4

2.安装编译工具

sudo yum install epel-release -y
sudo yum update
sudo yum install -y gcc gcc-c++ make cmake3 git openssl-devel
sudo ln -sf /usr/bin/cmake3 /usr/bin/cmake

执行完 update 后建议重启，因为连内核都升级了。

安装go环境 (用于编译taosAdapter，如果不准备编译taosAdapter，可以不安装。)

sudo yum install -y golang

go env -w GO111MODULE=on
go env -w GOPROXY=https://goproxy.cn,direct

如果没有安装go环境，编译时会报如下错误：

......
taosadapter no need cmake to config
[ 91%] Performing build step for 'taosadapter'
/bin/sh: go: command not found
make[2]: *** [tools/taosadapter/src/taosadapter-stamp/taosadapter-build] Error 127
make[1]: *** [tools/CMakeFiles/taosadapter.dir/all] Error 2
make: *** [all] Error 2

3.安装依赖包

sudo yum install -y zlib-devel zlib-static xz-devel snappy-devel jansson jansson-devel pkgconfig libatomic libatomic-static libstdc++-static openssl-devel

4.编译

mkdir debug
cd debug
cmake .. -DBUILD_HTTP=false  -DJEMALLOC_ENABLED=true
make

查看编译结果

[root@c3-14 debug]# ls build/bin/
asyncdemo     demo             jemalloc.sh  prepare  schemaless  stream_demo  taosadapter  tmq       tmq_sim       tsim
create_table  jemalloc-config  jeprof       runUdf   sml_test    taos         taosd        tmq_demo  tmq_taosx_ci  udfd

5.安装（非必要）

sudo make install

6.运行

如果没有执行 make install，要运行taosd，需要先将 libjemalloc.so 加入系统

[root@c3-14 debug]# cp build/lib/libjemalloc.so.2 /usr/local/lib/
[root@c3-14 debug]# echo "/usr/local/lib" > /etc/ld.so.conf.d/jemalloc.conf
[root@c3-14 debug]# ldconfig

6.1.配置taos

如果没有执行 make install，需要手动创建配置文件目录

[root@c3-14 debug]# mkdir /etc/taos
[root@c3-14 debug]# echo "fqdn   c3014" >>/etc/taos/taos.cfg

至少做个测试，仅配置一下FQDN即可。

6.2.运行服务端

[root@c3-14 debug]# cd build/bin/
[root@c3-14 bin]# ./taosd -V
community version: 3.0.2.4 compatible_version: 3.0.0.0
gitinfo: c534b3c755fad3b63e840bf3ac74e4677408ca80
buildInfo: Built at 2023-02-02 09:27:05
[root@c3-14 bin]# ./taosd 

......

6.3.运行客户端

[root@c3-14 bin]# ./taos
