1、Linux上源码方式安装postgresql12
01、准备操作系统环境
echo "192.168.1.61 tsepg61" >> /etc/hosts mount /dev/cdrom /mnt
02、安装pg所需要的依赖包
yum install -y cmake make gcc zlib gcc-c++ perl readline readline-devel zlib \
zlib-devel perl python36 tcl openssl ncurses-devel openldap pam
03、下载pg程序并上传到服务器
#PG这边用的安装包提供了yum和source源码方式
#所以生产环境为了方便管理就用源码source包安装合适些
04、创建pg普通用户
groupadd -g 60000 pgsql useradd -u 60000 -g pgsql pgsql echo "pgsql" |passwd --stdin pgsql
05、创建数据库相关目录
#安装目录：/postgresql/pg12
mkdir -p /postgresql/{pgdata,archive,scripts,backup,pg12,soft} chown -R pgsql:pgsql /postgresql chmod -R 775 /postgresql
06、源码安装postgresql
#进入pgsql用户开始解压pg源码 su - pgsql cd /postgresql/soft tar zxvf postgresql-12.2.tar.gz cd postgresql-12.2 #prefix是安装的目录，--without-readline代表命令行中不现实历史命令，就是history这个命令 ./configure --prefix=/postgresql/pg12 --without-readline make make install
07、配置数据库环境变量
su - pgsql vi ~/.bash_profile export LANG=en_US.UTF8 export PS1="[`whoami`@`hostname`:"‘$PWD]$‘ export PGPORT=5432 export PGDATA=/postgresql/pgdata export PGHOME=/postgresql/pg12 export LD_LIBRARY_PATH=$PGHOME/lib:/lib64:/usr/lib64:/usr/local/lib64:/lib:/usr/lib:/usr/local/lib:$LD_LIBRARY_PATH export PATH=$PGHOME/bin:$PATH:. export MANPATH=$PGHOME/share/man:$MANPATH
08、初始化数据库
su - pgsql /postgresql/pg12/bin/initdb -U postgres -D /postgresql/pgdata -E UTF8 --locale=en_US.utf8
09、配置参数文件
/postgresql/pgdata/postgresql.conf /postgresql/pgdata/pg_hba.conf su - pgsql
#pg服务启动 pg_ctl start pg_ctl stop
#or或者命令启动
nohup /postgresql/pg12/bin/postgres -D /postgresql/pgdata > /postgresql/pg12/pglog.out 2>&1 &
#or或者写成服务配置开机启动
vi /etc/systemd/system/postgresql.service [Unit] Description=PostgreSQL database server Documentation=man:postgres(1) [Service] Type=notify User=pgsql ExecStart= /postgresql/pg12/bin/postgres -D /postgresql/pgdata ExecReload=/bin/kill -HUP $MAINPID KillMode=mixed KillSignal=SIGINT TimeoutSec=0 [Install] WantedBy=multi-user.target
#相关的开机启动命令
systemctl enable postgresql
systemctl start postgresql
systemctl status postgresql
11、配置数据库超级用户密码
su - pgsql
psql \password postgres #or: alter user postgres with password ‘123456‘;
12、创建表测试
create table tsetbs (name varchar(50)); insert into tsetbs values(‘百度‘); insert into tsetbs values(‘阿里‘); insert into tsetbs values(‘腾讯‘); insert into tsetbs values(‘www.baidu.com‘); insert into tsetbs values(‘wx‘); insert into tsetbs values(‘yone-com‘); insert into tsetbs values(‘wx-gzh‘); insert into tsetbs values(‘yone_com‘); insert into tsetbs values(‘oracle‘); insert into tsetbs values(‘mysql‘); insert into tsetbs values(‘nosql‘); insert into tsetbs values(‘pgsql‘); insert into tsetbs values(‘深圳‘); insert into tsetbs values(‘广州‘); select * from tsetbs;
13、登陆及测试使用
psql -U postgres -h127.0.0.1 \
