Postgresql source code compilation and installation (linux-postgresql13.8)

1. Download the installation package

postgresql官方下载地址：https://www.postgresql.org/ftp/source/

2. Environmental preparation

1. Modify the maximum number of user processes

cat >> /etc/security/limits.conf << 'EOF'
* soft     nproc          65535
* hard     nproc          65535
* soft     nofile         65535
* hard     nofile         65535
EOF

2. Modify ordinary users

cat >> /etc/security/limits.d/90-nproc.conf << 'EOF'

*          soft     nproc          65535
*          hard     nproc          65535
*          soft     nofile         65535
*          hard     nofile         65535
EOF

3. Modify the number of file handles

cat >> /etc/sysctl.conf << 'EOF'
fs.file-max = 65536
EOF

4. Verification

 ulimit -a

5. Installation dependencies

yum install -y perl-ExtUtils-Embed readline-devel zlib-devel pam-devel libxml2-devel libxslt-devel openldap-devel  python-devel gcc-c++ openssl-devel cmake perl python36 tcl openssl-devel ncurses-devel openldap pam

3. Installation steps

decompress

tar -zxvf postgresql-13.8.tar.gz

Enter the installation directory

cd postgresql-13.8

Generate compiled files

/home/pgsql/ is the installation path, which can be modified as needed

./configure \
--prefix=/home/pgsql \
--bindir=/home/pgsql/bin \
--with-pgport=5432 \
--with-wal-blocksize=16 \
--with-segsize=1 \
--with-blocksize=8 \
--with-libedit-preferred \
--with-perl \
--with-openssl \
--with-libxml \
--with-libxslt \
--enable-thread-safety

compile

make -j4

Install

make -j4 install
