centos8自定义目录安装nginx(教程详解)

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 wwwuseradd -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-pcremake && 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 stopnginx -s quitngins -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=nginxAfter=network.target[Service]Type=forkingExecStart=nginxExecReload=nginx reloadExecStop=nginx quitPrivateTmp=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 0vim /etc/selinux/configSELINUX=disabled
