Kong API Gateway部署手册----安装
2016-10-25Linux撒加10006°c
A+ A-Changlog 2017年6月13日:
1、更新Kong为0.10.3
2、更新pcre为8.40
3、增加PGSQL的部署
4、OpenResty编译配置变更
5、升级OpenResty为1.11.2-2 (Kong 0.9.9支持的OpenResty版本为1.11.2-1)
6、增加serf的手动安装过程
Kong官方提供的源码安装方式还是略微显的简单了些,主要还是在突出Kong的安装,至于其他部分也就是寥寥带过。
源码安装Kong,需要准备的软件包有:
1、OpenResty 1.11.2-2
2、luarocks 2.42
3、pcre 8.40
4、openssl 1.0.2j+chacha20 patch
非必要模块或条件
1、Kong如果要部署在物理服务器上,CPU可以考虑使用E5-26xx v3或者v4的系列,因为AES-NI(可以去谷歌)
2、nginx-module-vts:第三方模块,用于输出更加详细的Nginx使用状态
操作系统版本 CentOS 6.5定制版,内核版本2.6.32-431.29.2

Kong：172.16.5.3
PostgreSQL：172.16.5.160
安装过程
172.16.5.160上的操作
下载OneSQL for PostgreSQL
mkdir -p /root/source/kong
cd /root/source/kong
wget https://www.onexsoft.cn/software/onepgsql-9.4.11-rhel5-linux64.tar.gz
安装PostgreSQL
tar zxf onepgsql-9.4.11-rhel5-linux64.tar.gz -C /opt/websuite/
mv /opt/websuite/pgsql9411 /opt/websuite/pgsql
#创建PGSQL用户及用户组
groupadd -g 26 -o -r postgres
useradd -M -g postgres -o -r -d /database/pgsql -s /bin/bash -N -u 26 postgres
#创建pgsql数据目录及日志目录
mkdir -p /database/pgsql/{data,logs}
chown -R postgres /database/pgsql
#添加环境变量
vi /etc/profile.d/pgsql.sh
export PATH=$PATH:/opt/websuite/pgsql/bin
export PG_HOME=/opt/websuite/pgsql
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:${PG_HOME}/lib
export PGDATA=/database/pgsql/data
export PGLOG=/database/pgsql/log/pgsql.log
#切换用户初始化PGSQL
su postgres
initdb -E utf8 -D /database/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/database/pgsql/data/pg_hba.conf
host kong kong 172.16.4.0/23 trust
新增的内容意思是允许172.16.4.0/23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='172.16.5.160'" /database/pgsql/data/postgresql.conf
#启动PGSQL
pg_ctl start -D /database/pgsql/data -l /database/pgsql/log/pgsql.log
#创建用户kong，根据提示设置用户kong的密码
createuser -l -E kong -P
#创建数据库kong
createdb -E utf8 -O kong kong
172.16.5.3上的操作
