Linux下nginx的yum安装、源码安装、OpenResty的源码安装

Linux下nginx的安装

安装环境：

# cat /proc/version
Linux version 3.10.0-123.el7.x86_64 ([email protected]) (gcc version 4.8.2 20140120 (Red Hat 4.8.2-16) (GCC) ) #1 SMP Mon Jun 30 12:09:22 UTC 2014

# cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core) 

yum安装

1. 设置yum仓库地址vi /etc/yum.repos.d/nginx.repo：

[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

2. 使用yum安装：

# yum install -y nginx

安装完成后配置文件所在目录为/etc/nginx。

2. nginx的启动与停止：

• 启动nginx：nginx或systemctl start nginx。
• 停止nginx：nginx -s stop或systemctl stop nginx。

3. 查看nginx是否启动成功。

# ps -ef|grep nginx
root       1830      1  0 22:45 ?        00:00:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf
nginx      1831   1830  0 22:45 ?        00:00:00 nginx: worker process
root       1835   1638  0 22:45 pts/0    00:00:00 grep --color=auto nginx

4. 访问网站http://localhost/。

5. 卸载nginx。

源码安装

源码安装的方式方便对nginx进行自定义的配置以及安装插件。

1. 下载源码，下载地址：http://nginx.org/en/download.html，这里使用的版本为nginx-1.18.0.tar.gz。

2. 解压nginx-1.18.0.tar.gz：

# tar xf nginx-1.18.0.tar.gz

3. 安装可能需要的依赖：

# yum -y install autoconf automake make
# yum -y install gcc gcc-c++
# yum -y install pcre pcre-devel    
# yum -y install zlib zlib-devel
# yum install -y openssl openssl-devel

4. 配置：

# cd nginx-1.18.0
# ./configure

5. 安装：

# make && make install

安装完成后的二进制文件和配置文件在/usr/local/nginx目录下。

6. 配置环境变量：

# vi /etc/profile
最后增加 export PATH=$PATH:/usr/local/nginx/sbin

# source /etc/profile

7. 安装成为服务：

# vi nginx.service

# systemctl daemon-reload

OpenResty的安装

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。

1. 下载OpenResty，下载地址：https://openresty.org/download/openresty-1.17.8.2.tar.gz。

2. 安装：

# tar xf openresty-1.17.8.2.tar.gz
# cd openresty-1.17.8.2
# ./configure
# make && make install

3. 配置环境变量：

# vi /etc/profile
最后追加 export PATH=$PATH:/usr/local/openresty/bin

# cd /usr/local/openresty/bin
# ll | grep openresty
lrwxrwxrwx. 1 root root    37 Oct  9 14:09 openresty -> /usr/local/openresty/nginx/sbin/nginx

openresty是一个指向/usr/local/openresty/nginx/sbin/nginx的软链接，其实openresty内置了一个nginx，使用方法与nginx一样。
