linux上离线部署nginx

准备

1. 下载nginx安装包
   [nginx: download](http://nginx.org/en/download.html)

2. 本次使用版本为：nginx-1.16.1.tar.gz

3. 部署的系统版本信息(CentOS Linux release 7.9.2009 (Core))

   Linux version 3.10.0-1160.el7.x86_64 ([email protected]) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC) ) #1 SMP Mon Oct 19 16:18:59 UTC 2020
   

4. 所需依赖环境提前上传(eg:/home/dagl/soft)

   gcc.zip 
   zlib-1.2.11.tar.gz 
   openssl-fips-2.0.10.tar.gz
   pcre-8.35.tar.gz
   

5. 安装前置环境

   unzip gcc.zip 
   cd /home/dagl/soft/gcc4.8.5-36
   rpm -Uvh *.rpm --nodeps --force
   #检查版本
   gcc -v
   g++ -v
   

   #编译安装 openssl
   cd /home/dagl/soft/
   tar zxvf openssl-fips-2.0.10.tar.gz
   cd openssl-fips-2.0.10
   

   #编译安装 pcre
   cd /home/dagl/soft
   tar zxf pcre-8.42.tar.gz
   cd pcre-8.42
   ./configure && make && make install
   #查看pcre版本
   pcre-config --version
   

   #安装zlib
   cd /home/dagl/soft/
   tar zxf zlib-1.2.11.tar.gz
   cd zlib-1.2.11
   ./configure && make && make install
   

开始

1. 上传nginx安装包至服务器 解压 （上传路径：/usr/local/）

tar zxvf nginx-1.16.1.tar.gz

2. 进入到nginx文件下（cd nginx-1.16.1）

./configure --prefix=/usr/local/nginx --user=nginx --group=nginx -–with-http_stub_status_module --with-http_ssl_module

#命令解释
##源码安装一般由3个步骤组成：配置（configure）、编译（make）、安装（make install）
./configure                     #可执行脚本
--prefix=/usr/local/nginx           #把所有的资源文件放在/usr/local/nginx路径中，不会杂乱
--user=nginx                    #指定用户
--group=nginx                   #指定用户组
-–with-http_stub_status_module \        #启用状态统计
-with-http_ssl_module               #启用SSL模块，提供SSL加密功能

如果出现此报错（缺少库）：

./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre= option.

解决：

yum -y install pcre-devel

3. 安装命令

make && make install

4. 添加环境变量

vi /etc/profile
export PATH=$PATH:/usr/local/nginx/sbin
source /etc/profile

5. 查看版本

nginx -V

nginx version: nginx/1.16.1
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC)
built with OpenSSL 1.0.2k-fips  26 Jan 2017
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module --with-http_ssl_module

6. 配置启动服务

vi /usr/lib/systemd/system/nginx.service
[Unit]
Description=nginx - high performance web server
After=network.target remote-fs.target nss-lookup.target
[Service]
Type=forking
ExecStart=/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/local/nginx/sbin/nginx -s stop

7. 重新加载并启动

#重新加载配置文件
systemctl daemon-reload
#启动nginx服务
systemctl start nginx.service
#设置开机启动
systemctl enable nginx.service
#查看运行状态
systemctl status nginx

如出现报错(nginx: [emerg] getpwnam("nginx") failed)：

Job for nginx.service failed because the control process exited with error code.See "systemctl status nginx.service" and "journalctl -xe" for details.

解决（创建nginx用户）：

useradd -s /sbin/nologin -M nginx

8. 权限不够

/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

9. 新建日志目录执行

mkdir /var/log/nginx

补充

安装过程出现问题

1. 可能缺少GCC和OpenSSL

yum install gcc-c++
yum install opensll openssl-devel

2. 安装zlib库（zlib 库提供了很多种压缩和解压缩的⽅式， nginx 使⽤ zlib 对 http 包的内容进⾏ gzip ，所以需要在 Centos 上安装 zlib 库）

yum install -y zlib zlib-devel
