Installation for Tars Master

Install CentOS 8, refer to https://phoenixnap.com/kb/how-to-install-centos-8
Install IEC, refer to IEC Type1&2 Installation Guide for R2
Install Tars, refer to https://tarscloud.github.io/TarsDocs_en/installation/source.html

1. Dependency install

yum install -y glibc-devel gcc gcc-c++ bison flex make cmake psmisc ncurses-devel zlib-devel openssl openssl-devel

## install mysql
wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql-community-server
yum -y install mysql-devel

If you have problems to install mysql with the above step, add the new mysql repository to local server with this yum command and then re-run the previous commands.

sudo yum localinstall https://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm

yum install mariadb-server -y

## Configure mysql
systemctl start mariadb.service
systemctl enable mariadb.service
systemctl status mariadb.service
mysql -u root -p

grep "password" /var/log/mariadb/mariadb.log

ALTER USER 'root'@'localhost' IDENTIFIED BY '${your passwd}';
flush privileges;

2. Install develop environment for Tars
yum install -y npm
npm i -g pm2

wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash
source ~/.bashrc

nvm install v8.11.3
npm install -g pm2 --registry=https://registry.npm.taobao.org

mkdir Tars
cd Tars
git clone https://github.com/TarsCloud/TarsFramework.git --recursive
cd TarsFramework/build
chmod u+x build.sh
./build.sh prepare
./build.sh all

###Recompile if needed.###

./build.sh cleanall
./build.sh all

Change to user root and create the installation directory.

cd /usr/local
mkdir tars
mkdir app
chown ${normal user}:${normal user} ./tars/
chown ${normal user}:${normal user} ./app/

cd
cd Tars/TarsFramework/build/
./build.sh install or make install

The default install path is /usr/local/tars/cpp。
If you want to install on different path:

**modify tarscpp/CMakeLists.txt**
**modify TARS_PATH in tarscpp/servant/makefile/makefile.tars**
**modify DEMO_PATH in tarscpp/servant/script/create_tars_server.sh**

firewall-cmd --zone=public --permanent --add-service=http
firewall-cmd --add-port 3000/tcp
firewall-cmd --add-port 3001/tcp
firewall-cmd --add-port 3306/tcp

3.1. Add user

mysql -u root -p
grant all on *.* to 'tarsAdmin'@'%' identified by 'Tars@2019' with grant option;
grant all on *.* to 'tarsAdmin'@'172.22.195.10' identified by 'Tars@2019' with grant option;
