1.安装工具和库

# PCRE是一个Perl库，包括 perl 兼容的正则表达式库。nginx 的 http 模块使用 pcre 来解析正则表达式

# 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

yum -y install gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel

2.目录结构

源码目录：/home/werben/pkgsrc/nginx
安装目录：/home/werben/application/nginx

3.下载解压源码

# 官网地址： https://nginx.org/en/download.html
wget -c https://nginx.org/download/nginx-1.17.5.tar.gz

4.创建用户组和用户

groupadd www
useradd -g www www

5.编译源码

./configure --user=www --group=www --prefix=/home/werben/application/nginx --with-http_v2_module --with-http_ssl_module --with-http_sub_module --with-http_stub_status_module --with-http_gzip_static_module --with-http_flv_module --with-http_mp4_module --with-pcre

make && make install

6.映射全局命令

ln -s /home/werben/application/nginx/sbin/nginx /usr/local/bin/nginx

7.启动，停止，重启

nginx -s stop
nginx -s quit
ngins -s reload

8.检测配置文件nginx.conf正确性

nginx  -t

9.开机自启动

vim /lib/systemd/system/nginx.service

[Unit]
Description=nginx
After=network.target

[Service]
Type=forking
ExecStart=nginx
ExecReload=nginx reload
ExecStop=nginx quit
PrivateTmp=true

[Install]
WantedBy=multi-user.target

#重新加载守护进程
systemctl daemon-reload

#启动nginx服务
systemctl start nginx.service
#停止nginx服务
systemctl stop nginx.service
#设置开机自启动
systemctl enable nginx.service
#停止开机自启动
systemctl disable nginx.service
#查看服务当前状态
systemctl status nginx.service
#重新启动服务
systemctl restart nginx.service
#查看所有已启动的服务
systemctl list-units --type=service

10.出现问题和解决方法

#如果`systemctl start nginx.service`提示如下报错

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

#执行
systemctl status nginx.service
#如果出现如下错误
    Process: 35783 ExecStart=...nginx/sbin/nginx(code=exitedstatus=203/EXEC)
    nginx.service: Control process exited, code=exited status=203
    systemd[1]: nginx.service: Failed with result 'exit-code'.
    localhost.localdomain systemd[1]: Failed to start nginx.


journalctl -xe

#如果看到如下信息          
    If you believe that systemd should be allowed execute access on the>
    Then you should report this as a bug.
    You can generate a local policy module to allow this access.
    Do allow this access for now by executing:
    # ausearch -c '(nginx)' --raw | audit2allow -M my-nginx
    # semodule -X 300 -i my-nginx.pp


#解决方法
setenforce 0
vim /etc/selinux/config
SELINUX=disabled
