1、恒生官网下载LightDB，这里以lightdb-x-13.3-22.2-5950-el7.x86_64.zip为例2、安装包上传到客户端服务器，解压并且给予相应的权限，系统用户我们以oracle为例
[oracle@node1 ~]$ cd /home/ta6/lightdb_client/lightdb-x-13.3-22.2-5950-kylinV10sp1.x86_64/lightdb-x/13.3-22.2/bin/ [oracle@node1 bin]$ pwd /home/ta6/lightdb_client/lightdb-x-13.3-22.2-5950-kylinV10sp1.x86_64/lightdb-x/13.3-22.2/bin
3、配置环境变量
[ta6@client bin]$ cat ~/.bashrc
# .bashrc
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
# Uncomment the following line if you don't like systemctl's auto-paging feature:
# export SYSTEMD_PAGER=
# User specific aliases and functions
export LIGHTDB_PORT=
export PGUSER=
export LIGHTDB_HOST=
export PGHOME=/home/ta6/lightdb_client/lightdb-x-13.3-22.2-5950-kylinV10sp1.x86_64/lightdb-x/13.3-22.2
export PGDATA=
export PATH=${PGHOME}/bin:${PGHOME}/tools/iftop/bin:${PGHOME}/tools/iotop/bin:${PGHOME}/tools/linux-ftools/bin:${PGHOME}/tools/vmtouch/bin:${PATH}
export LD_LIBRARY_PATH=${PGHOME}/lib:${PGHOME}/lib/ltext:${LD_LIBRARY_PATH}
export LTPORT=
export LTUSER=
export LTHOST=
export LTHOME=/home/ta6/lightdb_client/lightdb-x-13.3-22.2-5950-kylinV10sp1.x86_64/lightdb-x/13.3-22.2
export LTDATA=
export PATH=${LTHOME}/bin:${LTHOME}/tools/bin:${LTHOME}/tools/sbin:${PATH}
export LD_LIBRARY_PATH=${LTHOME}/lib:${LTHOME}/lib/ltext:${LTHOME}/tools/lib64:${LD_LIBRARY_PATH}
4、执行. ~/.bashrc 使环境变量生效 如果执行ltsql报如下错误
ltsql: error while loading shared libraries: libreadline.so.8: canot open shared object file
需要进入安装包下的system-lib目录使用root执行
rpm -ivh readline-8.0.3.ky10.x86_64.rpm
