一 简介：
Nginx (engine x) 是一个高性能的HTTP和反向代理服务器，也是一个IMAP/POP3/SMTP服务器。
官网地址：http://nginx.org/
二 编译安装Nginx
详细编译注释：===>>>点击进入
2.1.1更改阿里yum源
[root@centos7 ~]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
2.1.2 安装依赖工具
#建议安装pcre, zlib，前者为了重写rewrite，后者为了gzip压缩
[root@centos7 ~]# yum -y install pcre pcre-devel openssl openssl-devel gcc gcc-c++ autoconf automake zlib zlib-devel libxml2 libxml2-dev libxslt-devel gd-devel perl-devel perl-ExtUtils-Embed GeoIP GeoIP-devel GeoIP-data make GeoIP-devel GeoIP-update
2.1.3 创建Nginx运行用户和组及目录
[root@centos7 ~]# groupadd nginx
[root@centos7 ~]# useradd nginx -g nginx -s /sbin/nologin -M
[root@centos7 ~]# mkdir /tmp/nginx/client -p
[root@centos7 ~]# mkdir /var/tmp/nginx/proxy -p
2.1.4 下载Nginx1.15.2并编译安装
[root@centos7 tools]# wget http://nginx.org/download/nginx-1.15.2.tar.gz #解压 [root@centos7 tools]# tar xf nginx-1.15.2.tar.gz [root@centos7 tools]# cd nginx-1.15.2/ #--help可查看编译帮助 [root@centos7 nginx-1.15.2]# ./configure --help #配置 [root@centos7 nginx-1.15.2]# ./configure --prefix=/usr/local/nginx-1.15.2 --user=nginx --group=nginx --lock-path=/usr/local/nginx-1.15.2/lock --with-http_ssl_module --with-http_addition_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gzip_static_module --with-http_stub_status_module --with-http_perl_module --with-mail --with-mail_ssl_module --with-pcre --http-client-body-temp-path=/tmp/nginx/client/ --http-proxy-temp-path=/var/tmp/nginx/proxy --http-fastcgi-temp-path=/var/tmp/nginx/fcgi --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi --http-scgi-temp-path=/tmp/nginx/scgi --with-stream #查看返回值 [root@centos7 nginx-1.15.2]# echo $? 0 #编译安装 [root@centos7 nginx-1.15.2]# make -j 2 [root@centos7 nginx-1.15.2]# echo $? 0 [root@centos7 nginx-1.15.2]# make install [root@centos7 nginx-1.15.2]# echo $? 0
三 检查并验证启动
3.1.1 查看安装目录
[root@centos7 nginx-1.15.2]# cd /usr/local/nginx-1.15.2/ [root@centos7 nginx-1.15.2]# tree . ├── conf │ ├── fastcgi.conf │ ├── fastcgi.conf.default │ ├── fastcgi_params │ ├── fastcgi_params.default │ ├── koi-utf │ ├── koi-win │ ├── mime.types │ ├── mime.types.default │ ├── nginx.conf │ ├── nginx.conf.default │ ├── scgi_params │ ├── scgi_params.default │ ├── uwsgi_params │ ├── uwsgi_params.default │ └── win-utf ├── html │ ├── 50x.html │ └── index.html ├── logs └── sbin └── nginx 4 directories, 18 files
3.1.2 软连接
[root@centos7 nginx-1.15.2]# ln -sv /usr/local/nginx-1.15.2/ /usr/local/nginx "/usr/local/nginx" -> "/usr/local/nginx-1.15.2/" [root@centos7 nginx-1.15.2]# ln -sv /usr/local/nginx/sbin/nginx /usr/bin/nginx "/usr/bin/nginx" -> "/usr/local/nginx/sbin/nginx"
3.1.3 检查语法并启动
[root@centos7 ~]# nginx -t nginx: the configuration file /usr/local/nginx-1.15.2/conf/nginx.conf syntax is ok nginx: configuration file /usr/local/nginx-1.15.2/conf/nginx.conf test is successful [root@centos7 ~]# nginx [root@centos7 ~]# netstat -lnutp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 66669/nginx: master
四 编写启动脚本
[root@centos7 system]# cat /usr/lib/systemd/system/nginx.service [Unit] Description=nginx After=network.target [Service] Type=forking PIDFile=/usr/local/nginx/logs/nginx.pid ExecStartPre=/usr/local/nginx/sbin/nginx -t -q -g 'daemon on; master_process on;' ExecStart=/usr/local/nginx/sbin/nginx -g 'daemon on; master_process on;' ExecReload=/usr/local/nginx/sbin/nginx -g 'daemon on; master_process on;' -s reload ExecStop=-/sbin/start-stop-daemon --quiet --stop --retry QUIT/5 --pidfile /usr/local/nginx/logs/nginx.pid TimeoutStopSec=5 KillMode=mixed [Install] WantedBy=multi-user.target
测试
[root@centos7 system]# systemctl start nginx [root@centos7 system]# netstat -lnutp | grep 80 tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 67513/ng [root@centos7 system]# systemctl stop nginx [root@centos7 system]# netstat -lnutp | grep 80 [root@centos7 system]# systemctl restart nginx [root@centos7 system]# netstat -lnutp | grep 80 tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 67545/ng [root@centos7 system]# systemctl status nginx ● nginx.service - nginx Loaded: loaded (/usr/lib/systemd/system/nginx.service; disabled; vendor preset: disab Active: active (running) since 五 2018-08-10 14:05:21 CST; 13s ago Process: 67543 ExecStart=/usr/local/nginx/sbin/nginx -g daemon on; master_process on; Process: 67540 ExecStartPre=/usr/local/nginx/sbin/nginx -t -q -g daemon on; master_pro Main PID: 67545 (nginx) Tasks: 2 CGroup: /system.slice/nginx.service ├─67545 nginx: master process /usr/local/nginx/sbin/nginx -g daemon on; maste └─67546 nginx: worker process 8月 10 14:05:21 centos7.2 systemd[1]: Starting nginx... 8月 10 14:05:21 centos7.2 systemd[1]: Failed to read PID from file /usr/local/nginx/logs 8月 10 14:05:21 centos7.2 systemd[1]: Started nginx.
