一、安装工具及依赖
yum install -y wget make cmake gcc gcc-c++ \
yum install -y pcre pcre-devel lib zlib-devel && \
openssl openssl-devel
二、下载及解压nginx
wget http://nginx.org/download/nginx-1.12.2.tar.gz && \
tar -xzvf nginx-1.12.2.tar.gz && rm -f nginx-1.12.2.tar.gz && cd nginx-1.12.2
[root@localhost nginx-1.12.2]# pwd
/usr/local/nginx-1.12.2
三、编译安装
./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_realip_module --http-client-body-temp-path=/usr/local/var/tmp/nginx/client
--http-proxy-temp-path=/usr/local/var/tmp/nginx/proxy --http-fastcgi-temp-path=/usr/local/var/tmp/nginx/fcgi --http-scgi-temp-path=/usr/local/var/tmp/nginx/scgi --http-uwsgi-temp-path=/usr/local/var/tmp/nginx/uwsgi --with-http_geoip_module --with-http_stub_status_module
make && make install
四.检查安装
启动Nginx,启动完之后检查nginx是否已经正常启动
[root@localhost nginx-1.12.2]# /usr/local/nginx/sbin/nginx
[root@localhost nginx-1.12.2]# ps -ef |grep nginx
root 12563 1 0 14:44 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
nobody 12564 12563 0 14:44 ? 00:00:00 nginx: worker process
root 12568 3627 0 14:45 pts/1 00:00:00 grep --color=auto nginx
五、nginx常用命令
/usr/local/nginx/sbin/nginx -s start 启动nginx
/usr/local/nginx/sbin/nginx -s stop 关闭nginx
/usr/local/nginx/sbin/nginx -s reload 重启nginx
六、配置防火墙
[root@localhost nginx-1.12.2]# firewall-cmd --zone=public --add-port=80/tcp --permanent
success
[root@localhost nginx-1.12.2]# firewall-cmd --reload
success
七、测试nginx访问
通过浏览器访问nginx欢迎页,在地址栏输入:http://192.1680.122,如下图所示。
八、配置nginx
nginx最重要的配置文件nginx.conf
[root@localhost nginx-1.12.2]# vi /usr/local/nginx/conf/nginx.conf
#user nobody;#开启进程数 <=cpu数worker_processes 1;#错误日志保存位置#error_log logs/error.log;#error_log logs/error.log notice;#error_log logs/error.log info;#进程号保存文件#pid logs/nginx.pid;#每个进程最大连接数(最大连接=连接数x进程数)每个worker允许同时产生多少个链接,默认1024events {worker_connections 1024;}http { #文件扩展名与文件类型映射表include mime.types; #默认文件类型default_type application/octet-stream; #日志文件输出格式 这个位置相于全局设置#log_format main '$remote_addr - $remote_user [$time_local] "$request" '# '$status $body_bytes_sent "$http_referer" '# '"$http_user_agent" "$http_x_forwarded_for"'; #请求日志保存位置#access_log logs/access.log main; #打开发送文件sendfile on;#tcp_nopush on;#keepalive_timeout 0; #连接超时时间keepalive_timeout 65;#打开gzip压缩 #gzip on;server { #监听端口listen 80;#监听域名 server_name localhost;#charset koi8-r;#nginx访问日志放在logs/host.access.log下,并且使用main格式(还可以自定义格式) #access_log logs/host.access.log main; #如果没有location更明确的匹配访问路径的话,访问请求都会被该location处理location / { #root指定nginx的根目录为/usr/local/nginx/htmlroot html; #默认访问文件,欢迎页先去html目录下找index.html,如果找不到再去找index.htmindex index.html index.htm;}#error_page 404 /404.html;# redirect server error pages to the static page /50x.html# #错误页面及其返回地址,错误码为500、502、503、504都会返回50.html错误页面。error_page 500 502 503 504 /50x.html;location = /50x.html {root html;}# proxy the PHP scripts to Apache listening on 127.0.0.1:80##location ~ \.php$ {# proxy_pass http://127.0.0.1;#}# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000##location ~ \.php$ {# root html;# fastcgi_pass 127.0.0.1:9000;# fastcgi_index index.php;# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;# include fastcgi_params;#}# deny access to .htaccess files, if Apache's document root# concurs with nginx's one##location ~ /\.ht {# deny all;#}}# another virtual host using mix of IP-, name-, and port-based configuration##server {# listen 8000;# listen somename:8080;# server_name somename alias another.alias;# location / {# root html;# index index.html index.htm;# }#}# HTTPS server##server {# listen 443 ssl;# server_name localhost;# ssl_certificate cert.pem;# ssl_certificate_key cert.key;# ssl_session_cache shared:SSL:1m;# ssl_session_timeout 5m;# ssl_ciphers HIGH:!aNULL:!MD5;# ssl_prefer_server_ciphers on;# location / {# root html;# index index.html index.htm;# }#}}
配置文件里可以添加多个server,server监听的端口不同,可以根据需要让nginx代理多个端口,每个端口指定去做某些事情。
9、脚本安装nginx
#!/usr/bin/env bashecho -e '\e[31mInstallation tools and dependencies\e[0m'yum install -y wget make cmake gcc gcc-c++yum install -y pcre-devel lib zlib-devel openssl openssl-develif [ $? -eq 0 ];thenecho -e '\e[32mSuccessful!\e[0m'elseecho -e '\e[31mFailed\e[0m'exit 0fiecho -e '\e[31mInstallation nginx\e[0m'wget http://nginx.org/download/nginx-1.12.2.tar.gz \tar -xzvf nginx-1.12.2.tar.gz && rm -f nginx-1.12.2.tar.gz && cd nginx-1.12.2 \./configure --prefix=/usr/local/nginx \make && make installif [ $? -eq 0 ];thenecho -e '\e[32mSuccessful!\e[0m'elseecho -e '\e[31mFailed\e[0m'exit 0fiecho -e '\e[31mStart nginx\e[0m'/usr/local/nginx/sbin/nginxecho -e '\e[32mSuccessful!\e[0m'
亲测成功!主要防火墙开放80端口!
9、创建nginx启动命令脚本
vi /etc/init.d/nginx
#! /bin/bash# chkconfig: - 85 15PATH=/usr/local/nginxDESC="nginx daemon"NAME=nginxDAEMON=$PATH/sbin/$NAMECONFIGFILE=$PATH/conf/$NAME.confPIDFILE=$PATH/logs/$NAME.pidSCRIPTNAME=/etc/init.d/$NAMEset -e[ -x "$DAEMON" ] || exit 0do_start() {$DAEMON -c $CONFIGFILE || echo -n "nginx already running"}do_stop() {$DAEMON -s stop || echo -n "nginx not running"}do_reload() {$DAEMON -s reload || echo -n "nginx can't reload"}case "$1" instart)echo -n "Starting $DESC: $NAME"do_startecho ".";;stop)echo -n "Stopping $DESC: $NAME"do_stopecho ".";;reload|graceful)echo -n "Reloading $DESC configuration..."do_reloadecho ".";;restart)echo -n "Restarting $DESC: $NAME"do_stopdo_startecho ".";;*)echo "Usage: $SCRIPTNAME {start|stop|reload|restart}" >&2exit 3;;esacexit 0
chmod a+x /etc/init.d/nginx #设置执行权限
chkconfig --add nginx #注册成服务
chkconfig nginx on #设置开机启动
#启动nginx服务
service nginx start
#停止nginx服务
service nginx stop
#重启nginx服务
service nginx restart
#重新读取nginx配置(这个最常用, 不用停止nginx服务就能使修改的配置生效)
service nginx reload
