开发笔记:安装指定版本openrestynginx

篇首语：本文由编程笔记#小编为大家整理，主要介绍了安装指定版本openresty-nginx相关的知识，希望对你有一定的参考价值。

OpenResty介绍

以下介绍内容引用于​​OpenResty官网，更多信息可进入官网。​​

OpenResty^® 是一个基于 ​​Nginx​​ 与 Lua 的高性能 Web 平台，其内部集成了大量精良的 Lua 库、第三方模块以及大多数的依赖项。用于方便地搭建能够处理超高并发、扩展性极高的动态 Web 应用、Web 服务和动态网关。

OpenResty^® 通过汇聚各种设计精良的 ​​Nginx​​ 模块（主要由 OpenResty 团队自主开发），从而将 ​​Nginx​​ 有效地变成一个强大的通用 Web 应用平台。这样，Web 开发人员和系统工程师可以使用 Lua 脚本语言调动 ​​Nginx​​ 支持的各种 C 以及 Lua 模块，快速构造出足以胜任 10K 乃至 1000K 以上单机并发连接的高性能 Web 应用系统。

OpenResty^® 的目标是让你的Web服务直接跑在 ​​Nginx​​ 服务内部，充分利用 ​​Nginx​​ 的非阻塞 I/O 模型，不仅仅对 HTTP 客户端请求,甚至于对远程后端诸如 mysql、PostgreSQL、Memcached 以及 Redis 等都进行一致的高性能响应。

系统适用范围

使用范围：centos类操作系统 \\ redhat操作系统

安装过程1-系统环境检查

查看操作系统版本
[root@10-13-135-162 ~]# cat /etc/system-release
CentOS Linux release 7.9.2009 (Core)
[root@10-13-135-162 ~]# uname -a
Linux 10-13-135-162 4.19.188-10.el7.ucloud.x86_64 #1 SMP Wed Apr 28 09:54:38 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
查看系统用户为root
[root@10-13-135-162 ~]# id
uid=0(root) gid=0(root) groups=0(root)
确认服务器能上网
[root@10-13-135-162 ~]# ping -c2 baidu.com
PING baidu.com (220.181.38.148) 56(84) bytes of data.
64 bytes from 220.181.38.148 (220.181.38.148): icmp_seq=1 ttl=48 time=40.7 ms

--- baidu.com ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 1001ms
rtt min/avg/max/mdev = 40.665/40.712/40.759/0.047 ms

安装过程2-OpenResty配置yum源

OpenResty配置源
[root@10-13-135-162 ~]# yum-config-manager --add-repo https://openresty.org/package/centos/openresty.repo
清空操作系统yum离线缓存
[root@10-13-135-162 ~]# yum clean all
更新操作系统yum离线缓存
[root@10-13-135-162 ~] yum makecache

安装过程3-OpenResty支持yum版本

查看OpenResty可以安装的yum版本
[root@10-13-135-162 ~]# yum list openresty --showduplicates
Loaded plugins: fastestmirror, langpacks, versionlock
Loading mirror speeds from cached hostfile
Excluding 1 update due to versionlock (use "yum versionlock status" to show it)
Installed Packages
openresty.x86_64 1.19.3.1-1.el7 @openresty
Available Packages
openresty.x86_64 1.17.8.1-1.el7 openresty
openresty.x86_64 1.17.8.2-1.el7 openresty

openresty.x86_64 1.19.3.2-1.el7 openresty
openresty.x86_64 1.19.9.1-1.el7 openresty
安装指定版本OpenResty
[root@10-13-135-162 ~]# yum install -y openresty-1.19.3.1-1.el7
语法格式: yum install -y openresty-[xx版本].[xx操作系统]
OpenResty安装后效果-yum检查
[root@10-13-135-162 tmp]# yum info openresty-1.19.3.1-1.el7
Loaded plugins: fastestmirror, langpacks, versionlock
Loading mirror speeds from cached hostfile
Excluding 1 update due to versionlock (use "yum versionlock status" to show it)
Installed Packages
Name : openresty
Arch : x86_64
Version : 1.19.3.1
Release : 1.el7
Size : 3.4 M
Repo : installed
From repo : openresty
Summary : OpenResty, scalable web platform by extending nginx with Lua
URL : https://openresty.org/
License : BSD
Description : This package contains the core server for OpenResty. Built for production
: uses.
:
: OpenResty is a full-fledged web platform by integrating the standard Nginx
: core, LuaJIT, many carefully written Lua libraries, lots of high quality
: 3rd-party Nginx modules, and most of their external dependencies. It is
: designed to help developers easily build scalable web applications, web
: services, and dynamic web gateways.
:
: By taking advantage of various well-designed Nginx modules (most of which
: are developed by the OpenResty team themselves), OpenResty effectively
: turns the nginx server into a powerful web app server, in which the web
: developers can use the Lua programming language to script various existing
: nginx C modules and Lua modules and construct extremely high-performance
: web applications that are capable to handle 10K ~ 1000K+ connections in
: a single box.
OpenResty安装后效果-rpm检查
[root@10-13-135-162 ~]# rpm -qa|grep -Ei "openresty"
openresty-pcre-8.44-1.el7.x86_64
openresty-openssl111-1.1.1l-1.el7.x86_64
openresty-1.19.3.1-1.el7.x86_64
openresty-zlib-1.2.11-3.el7.centos.x86_64

安装过程4-OpenResty日志自动轮转压缩

设置OpenResty的日志自动轮转压缩 -- (不设置服务器磁盘空间就用没的)
[root@10-13-135-162 ~]# cat /etc/logrotate.d/nginx
/var/log/nginx/*.log
daily
missingok
rotate 52
compress
delaycompress
notifempty
create 640 nginx nginx
sharedscripts
postrotate
if [ -f /usr/local/openresty/nginx/logs/nginx.pid ]; then kill -USR1 `cat /usr/local/openresty/nginx/logs/nginx.pid`
fi
endscript

安装过程5-OpenResty启动与开机启动

这里的systemctl命令是内核3.0以上版本才有，我所用操作系统为centos7
设置启动加载 (为了让进程在查看的时候,更美观，个人喜好)
