安装依赖：
apt install -y zlib1g-dev gcc make libreadline-dev libreadline8 libssh-dev
sudo apt-get install libcurl4-openssl-dev
上传软件包
生产限制联网，需要工作机上传
postgresql-14.9.tar.gz
解压及安装
mkdir -p /usr/local/pgsql/14/
cd /data/soft/ && tar xzfv postgresql-14.9.tar.gz
cd /data/soft/postgresql-14.9 && ./configure --prefix=/usr/local/pgsql/14 --with-openssl
make && make install
cd /usr/local/pgsql/14/ && ls -hl
添加postgres用户：（有密码，记录一下密码，安全会侦测没有密码的用户）
adduser postgres
配置环境变量
root账号下：
vim /etc/profile
export PATH=/usr/local/pgsql/14/bin:$PATH
LANG=en_US.UTF-8
LC_TIME=en_US.UTF-8
LC_ALL="en_US.UTF-8"
lc_collate="en_US.UTF-8"
postgres用户下：
su - postgres
source /home/postgres/.bash_profile
vim /home/postgres/.bash_profile
export PGHOME=/usr/local/pgsql/14
export PGDATA=/data/pgsql14/5432/data
export PGPORT=5432
export PGUSER=postgres
export PATH=PGHOME/bin:PATH:$HOME/bin
export LD_LIBRARY_PATH=$PGHOME/lib
export PGUSER=postgres
export PGHOST=$PGDATA
alias rm='rm -i'
alias ll='ls -lh'
export LANG=en_US.UTF-8
export LC_TIME=en_US.UTF-8
export LC_ALL="en_US.UTF-8"
export lc_collate="en_US.UTF-8"
创建数据路径：（使用port：5432示例)
mkdir -p /data/pgsql14/5432/{data,archive}
chown -R postgres:postgres /usr/local/pgsql/ /data/pgsql14/
chmod -R go-rwx /data/pgsql14/5432/
初始化数据库：
su - postgres
/usr/local/pgsql/14/bin/initdb -D /data/pgsql14/5432/data
cd /data/pgsql14/5432/data && ls
修改配置文件：
修改pg_hba.conf
修改 postgresql.conf（已经与安全沟通确认，生产无需开ssl）
补充： random_page_cost 的值改为 1.0（SSD） 默认是4机械盘
