centos 7.4 + yugabytedb 2.5

os: centos 7.4.1708
db: yugabytedb 2.5

参考《centos 7.x 安装 yugabytedb 的优化设置》设置好centos 7.4

setup python

yugabytedb 2.5 需要 python 环境，2.5 版本 对 python2 或者 python3 都可以
python2 安装如下

# yum install python python-libs python-devel python2-pip

python3 安装如下

# yum install -y python3 python3-libs python3-devel python3-pip python3-setuptools

# alternatives --set python /usr/bin/python3

create user

# groupadd -g 5000 yugabyte;
useradd -g yugabyte -u 5000 yugabyte -d /home/yugabyte;
usermod -g yugabyte yugabyte;
mkdir -p /var/lib/yugabytedb; 
chown -R yugabyte:yugabyte /var/lib/yugabytedb;

yugabyte 用户的环境变量，先占位，后面修改

# vi /home/yugabyte/.bash_profile

export PGHOME=/usr/yugabytedb-
export PGDATA=/var/lib/yugabytedb 

export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${PGHOME}/lib
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/lib:/usr/lib:/usr/local/lib
export PATH=${PGHOME}/bin:$PATH
export MANPATH=${PGHOME}/share/man:$MANPATH

export TMP=/tmp
export TEMP=/tmp
export TMPDIR=/tmp

download、setup

# cd /usr
# wget https://downloads.yugabyte.com/yugabyte-2.5.1.0-linux.tar.gz
# tar xvfz yugabyte-2.5.1.0-linux.tar.gz
# chown -R yugabyte:yugabyte ./yugabyte-2.5.1.0

# su - yugabyte
$ cd /usr/yugabyte-2.5.1.0
$ ./bin/post_install.sh

startup(RF=1)

To create a single-node local cluster with a replication factor (RF) of 1
该方式只能初步试用，没有HA。

# su - yugabyte
$ cd /usr/yugabyte-2.5.1.0

$ ./bin/yugabyted start --base_dir=/var/lib/yugabytedb/node1 --listen=127.0.0.1
