install as root
Create a user compiled a successful installation, the next step is to create a regular user because the default superuser (root) can not start postgresql, so you need to create a normal user to start the database, create a user execute the following command: [root @ localhost build_dir ] # groupadd postgres [root @ localhost build_dir] # useradd - G postgres postgres [root @ localhost build_dir] # passwd postgres Next, set permissions, assign all data directory pg postgres user, execute the following command: [root @ localhost build_dir ] # chown -R Postgres: Postgres / usr / local / pgSQL to create the directory [root @ localhost build_dir] # mkdir -p / mnt / db1 / PGDATA / pgSQL / mnt / db1 / PGDATA / pgtbs / mnt / db1 / ARCHIVELOG / Backups [build_dir the root @ localhost] # the chmod -R & lt 775 / mnt / DB1 [root@localhost build_dir]# chown -R postgres:postgres /mnt/db1 设置环境变量 [root@localhost build_dir]# vi /home/postgres/.bash_profile PATH=$PATH:$HOME/.local/bin:$HOME/bin export PATH export PGPORT=8432 export PGHOME=/usr/local/pgsql export PGDATA=/mnt/db1/pgdata/pgsql export PATH=$PGHOME/bin:$PATH export MANPATH=$PGHOME/share/man:$MANPATH export LANG=en_US.UTF-8 export DATE='+ DATE "the Y% m%%% D% H M" ' Export the LD_LIBRARY_PATH = $ PGHOME / lib: $ the LD_LIBRARY_PATH Export the PGHOST = $ PGDATA is Export PGUSER = Postgres Export PGDATABASE = Postgres the PATH = the PATH $: $ the HOME / .local / bin : $ the HOME / bin: $ PGHOME / bin Export the PATH execute the following command to take effect: [root @ localhost build_dir] # Source /home/postgres/.bash_profile
