1、环境准备：Centos 7 minimal x64

yum install net-tools vima.setsebool -P httpd_can_network_connect 1b.setenforce 0 (临时性)c.修改/etc/selinux/config 文件  将SELINUX=enforcing改为SELINUX=disabled  重启机器即可

其中a,b,c是关闭SElinux的，如果不关闭，就会出现Wiki怎么也连不上数据库的。

yum install httpd -y

3、安装php环境：

rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpmrpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpmyum install -y php55w.x86_64 php55w-cli.x86_64 php55w-common.x86_64 php55w-gd.x86_64 php55w-intl.x86_64 php55w-xml.x86_64 php55w-mbstring.x86_64 php55w-pgsql.x86_64

4、安装数据库：

yum install -y flex bison readline-devel zlib-devel openssl-devel libxml2-devel libxslt-devel git gccuseradd postgressu - postgresgit clone git://git.postgresql.org/git/postgresql.git pg9.6cd pg9.6git checkout REL9_6_STABLE./configure --prefix=/home/postgres/pgdb9.6 --with-opensslmake; make installcd contribmake; make installcd; cd pgdb9.6cd bin./initdb -D ../data./pg_ctl -D ../data start./psql
