机器分配

Kong：10.95.196.149/150

PostgreSQL：10.95.196.149

PostgreSQL安装过程

10.95.196.149上的操作

下载PostgreSQL，

postgresql-9.6.6.tar.gz

#创建PGSQL用户及用户组

groupadd -g 26 -o -r postgres

useradd -M -g postgres -o -r -d /home/pgsql -s /bin/bash  -u 26 postgres

#创建pgsql数据目录及日志目录

mkdir -p /home/pgsql/{data,logs}

chown -R postgres /home/pgsql

#切换用户初始化PGSQL

su postgres

#添加环境变量

vi  .bash_profile

PGHOME=/home/pgsql/postgresql-9.6.6

export PGHOME

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PGHOME/lib

export PGLOG=/home/pgsql/logs/pgsql.log

PGDATA=/home/pgsql/data

export PGDATA

PATH=$PATH:$HOME/.local/bin:$HOME/bin:$PGHOME/bin

export PATH

---

初始化postgresql

initdb -E utf8 -D /home/pgsql/data -W -U postgres

注：以下操作均在postgres环境下操作

#增加PGSQL访问权限，修改/home/pgsql/data/pg_hba.conf

host    kong149            kong149            10.95.196.0/24           trust

新增的内容意思是允许10.95.196.0/24网段的机器可以使用用户kong访问数据库kong

#调整PGSQL的监听地址

sed -i "/#listen_addresses/c listen_addresses='10.95.196.149'" /home/pgsql/data/postgresql.conf

#启动PGSQL

pg_ctl start -D /home/pgsql/data -l /home/pgsql/logs/pgsql.log

#创建用户kong，根据提示设置用户kong的密码

createuser -l -E kong149 -P 

根据提示输入密码 ui8ga$No

#创建数据库kong

createdb -E utf8 -O kong149  kong149

---

10.95.196.149-150上的操作

安装一些另外的包

yum install devtoolset-3-gcc devtoolset-3-gcc-c++ devtoolset-3-libstdc++-devel gperftools-devel gperftools-libs

下载源码包

mkdir -p /home/package

cd  /home/package

wget https://openresty.org/download/openresty-1.11.2.4.tar.gz

wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.40.tar.gz

wget https://www.openssl.org/source/openssl-1.0.2j.tar.gz

wget http://luarocks.github.io/luarocks/releases/luarocks-2.4.2.tar.gz

git clone https://github.com/cloudflare/sslconfig.git

wget https://github.com/Mashape/kong/archive/0.10.3.tar.gz -O kong-0.10.3.tar.gz

以上包可以直接对对应网站下载，服务器直接下可以遇到ssl无法握手问题；

安装OpenSSL

tar -xf openssl-1.0.2n.tar.gz  #-xzvf解压安装会遇到问题，不清楚原因

cd  openssl-1.0.2n

patch -p1 

./config threads shared

make depend

make && make install

默认安装到 /usr/local/ssl 对应下面编译中ssl环境目录需要相应变更

安装OpenResty

#创建用户及用户组  也可以不创建

groupadd websuite

useradd -g websuite -M -s /sbin/nologin websuite

---

#编译安装openresty

tar -xf 

openresty-1.11.2.4.tar.gz

tar -xf pcre-8.40.tar.gz

#创建OpenResty所需目录

mkdir -p /usr/local/kong/{run,logs,conf}

mkdir -p /usr/local/kong/temp/{client,proxy}

cd  openresty-1.11.2.4

安装luarocks

tar zxf luarocks-2.4.2.tar.gz

cd luarocks-2.4.2

./configure --prefix=/usr/local/kong \

--rocks-tree=/usr/local/kong/luajit \

make build

make install

echo 'export PATH="${PATH}:/usr/local/kong/bin:/usr/local/kong/sbin:/usr/local/kong/luajit/bin"' > /etc/profile.d/kong.sh

source /etc/profile.d/kong.sh

把下载的luarocks-2.4.2-1.src.rock 放到luarocks-2.4.2目录下执行：

luarocks install luarocks-2.4.2-1.src.rock

---

安装Kong

tar -xf kong-0.11.0.tar.gz

cd kong-0.11.0

sed -i '/OPENSSL_DIR ?=/c OPENSSL_DIR ?= /usr/local/ssl' Makefile

make install

cp -r bin/* /usr/local/kong/bin/

安装

HiRes组件

yum -y  install perl-Time-HiRes

建立软连接

ln -f -s /usr/local/ssl/lib/libssl.so.1.0.0 /lib64/libssl.so.1.0.0

ln -f -s /usr/local/ssl/lib/libcrypto.so.1.0.0 /lib64/libcrypto.so.1.0.0

启动Kong

kong start or kong start -vv(如果执行kong start报错，可以使用kong start -vv来进行调试)

如遇数据库表结构不兼容 执行kong migrations up
