Nginx安装及配置

创建nginx管理用户

先添加应用工作组，再创建nginx工作目录

# 创建app用户组ID为6666 
groupadd -g 6666 app 
# 添加nginx用户指定工作目录为/app/nginx 
useradd -g app -u 6660 nginx -d /app/nginx

下载nginx

在等待下载文件的过程中可以先配置后面的快捷命令和环境变量

wget http://nginx.org/download/nginx-1.23.1.tar.gz -O nginx-1.23.1.tar.gz
# 解压压缩包

tar -zxf nginx-1.23.1.tar.gz

下载pcre2

下载文件并保存为pcre2-10.40.tar.gz

wget https://github.com/PCRE2Project/pcre2/releases/download/pcre2-10.40/pcre2-10.40.tar.gz -O pcre2-10.40.tar.gz
# 解压压缩包
tar -zxf pcre2-10.40.tar.gz

下载zlib

下载文件并保存为zlib-1.2.12.tar.gz

wget http://www.zlib.net/zlib-1.2.12.tar.gz -O zlib-1.2.12.tar.gz
# 解压压缩包
tar -zxf zlib-1.2.12.tar.gz

下载openssl

下载文件并保存为openssl-3.0.5.tar.gz

wget http://artfiles.org/openssl.org/source/openssl-3.0.5.tar.gz -O openssl-3.0.5.tar.gz
# 解压压缩包
tar -zxf openssl-3.0.5.tar.gz

配置nginx编译参数

主要调整--prefix=path即可

cd nginx-1.23.1
# 配置编译参数
./configure \
--prefix=/app/nginx \
--with-threads \
--with-file-aio \
--with-http_ssl_module \
--with-http_v2_module \
--with-http_realip_module \
--with-http_addition_module \
--with-http_geoip_module=dynamic \
--with-http_sub_module \
--with-http_gunzip_module \
--with-http_gzip_static_module \
--with-http_auth_request_module \
--with-http_random_index_module \
--with-http_secure_link_module \
--with-http_slice_module \
--with-http_stub_status_module \
--with-mail=dynamic \
--with-stream \
--with-stream=dynamic \
--with-stream_ssl_module \
--with-stream_realip_module \
--with-stream_geoip_module \
--with-stream_geoip_module=dynamic \
--with-stream_ssl_preread_module \
--with-pcre=../pcre2-10.40 \
--with-zlib=../zlib-1.2.12 \
--with-openssl=../openssl-1.1.1q
# 执行编译和安装
make && make install

配置快捷命令

配置sudo权限

# 在/etc/sudoers.d/路径添加nginx命令文件
cd /etc/sudoers.d/ && vi nginx
# 添加如下内容后保存退出
nginx ALL= NOPASSWD:/app/nginx/sbin/run.sh
nginx ALL= NOPASSWD:/app/nginx/sbin/nginx -s reload
nginx ALL= NOPASSWD:/app/nginx/sbin/nginx -t

添加nginx管理脚本

在/app/nginx/sbin/目录下添加run.sh脚本，在/app/nginx/目录下添加nginx.sh脚本

#在/app/nginx/sbin/目录下添加run.sh脚本
cd /app/nginx/sbin/ && touch run.sh && chmod a+x run.sh

# 将下面内容完整复制到run.sh中

#!/bin/bash
# nginx Startup script for the Nginx HTTP Server
# this script create it by jackbillow at 2007.10.15.
# it is v.0.0.2 version.
# if you find any errors on this scripts,please contact jackbillow.
# and send mail to jackbillow at gmail dot com.

添加环境变量

在.bash_profile中添加如下生效语句

# User specific environment and startup programs
if [ -f ~/.profile ]; then
. ~/.profile
fi

在 /app/nginx目录新建.profile文件，添加下面内容到.profile中

#命令设置
alias start="sh ~/nginx.sh start"
alias stop="sh ~/nginx.sh stop"
alias restart="sh ~/nginx.sh restart"
alias reload="sh ~/nginx.sh reload"
alias status="sh ~/nginx.sh status"
alias check="sh ~/nginx.sh check"
alias conf="/bin/vi ~/conf/nginx.conf"
export NGX_HOME="/app/nginx"
export NGINX_CONF="$NGX_HOME/conf/nginx.conf"
alias log="cd ~/logs"
alias l='ls -l'
alias lf='ls -F'
alias rm="hrm"
hrm() {
echo "警告：生产系统禁止使用rm命令!!!"
}

#系统环境变量
export PS1='\h:''$PWD>'
set -o vi

echo "#######################################"
echo "# Nginx快捷命令 #"
echo "#######################################"
echo "  start 启动nginx"
echo "   stop 关闭nginx"
echo "restart 重启nginx"
echo " reload 重新加载nginx"
echo " status 查看nginx运行状态"
echo "  check 检查nginx.conf配置是否正确"
echo "   conf 修改nginx配置文件nginx.conf"
echo "    log 跳转到nginx日志目录"
echo "#######################################"

添加环境变量后需要source .bash_profile进行生效，或者重新登录系统会自动生效
