https://coding.net/u/aminglinux/p/nginx/git/blob/master/2z/nginx.repocss
1.安装最新稳定版本,能够安装epel-release扩展源,可是用epel安装的这个版本比较老,咱们这里用yum nignx源安装,建立一个nginx yum源html
[root@centos-03 ~]# vim /etc/yum.repos.d/nginx.repo^C [root@centos-03 ~]# cat /etc/yum.repos.d/nginx.repo [nginx] name=nginx repo baseurl=http://nginx.org/packages/centos/$releasever/$basearch/ gpgcheck=0 enabled=1 [root@centos-03 ~]#
2.用yum list命令查看下nginx的版本,若是有epel的源,为了不产生冲突咱们将epel源先关掉linux
[root@centos-03 ~]# mv /etc/yum.repos.d/epel.repo epel.repo.bak
3.咱们以前安装过nginx包先卸载掉nginx
[root@centos-03 ~]# yum remove nginx-filesystem
[root@centos-03 ~]# yum list | grep nginx nginx.x86_64 1:1.14.0-1.el7_4.ngx nginx nginx-debug.x86_64 1:1.8.0-1.el7.ngx nginx nginx-debuginfo.x86_64 1:1.14.0-1.el7_4.ngx nginx nginx-module-geoip.x86_64 1:1.14.0-1.el7_4.ngx nginx nginx-module-geoip-debuginfo.x86_64 1:1.14.0-1.el7_4.ngx nginx nginx-module-image-filter.x86_64 1:1.14.0-1.el7_4.ngx nginx nginx-module-image-filter-debuginfo.x86_64 1:1.14.0-1.el7_4.ngx nginx nginx-module-njs.x86_64 1:1.14.0.0.2.2-1.el7_4.ngx nginx nginx-module-njs-debuginfo.x86_64 1:1.14.0.0.2.2-1.el7_4.ngx nginx nginx-module-perl.x86_64 1:1.14.0-1.el7_4.ngx nginx nginx-module-perl-debuginfo.x86_64 1:1.14.0-1.el7_4.ngx nginx nginx-module-xslt.x86_64 1:1.14.0-1.el7_4.ngx nginx nginx-module-xslt-debuginfo.x86_64 1:1.14.0-1.el7_4.ngx nginx nginx-nr-agent.noarch 2.0.0-12.el7.ngx nginx pcp-pmda-nginx.x86_64 3.12.2-5.el7 base [root@centos-03 ~]#
4.开始yum安装nginxgit
[root@centos-03 ~]# yum install -y nginx
5.启动nginxweb
[root@centos-03 ~]# systemctl start nginx [root@centos-03 ~]# ps aux|grep nginx root 2702 0.0 0.0 48524 972 ? Ss 23:46 0:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf nginx 2703 0.0 0.1 48928 1924 ? S 23:46 0:00 nginx: worker process root 2705 0.0 0.0 112660 964 pts/0 R+ 23:46 0:00 grep --color=auto nginx [root@centos-03 ~]# netstat -lntp 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 2702/nginx: master tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1419/sshd tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 2521/master tcp6 0 0 :::22 :::* LISTEN 1419/sshd tcp6 0 0 ::1:25 :::* LISTEN 2521/master [root@centos-03 ~]#
6.curl访问nginx算法
[root@centos-03 ~]# curl 192.168.242.133 <!DOCTYPE html> <html> <head> <title>Welcome to nginx!</title> <style> body { width: 35em; margin: 0 auto; font-family: Tahoma, Verdana, Arial, sans-serif; } </style> </head> <body> <h1>Welcome to nginx!</h1> <p>If you see this page, the nginx web server is successfully installed and working. Further configuration is required.</p> <p>For online documentation and support please refer to <a href="http://nginx.org/">nginx.org</a>.<br/> Commercial support is available at <a href="http://nginx.com/">nginx.com</a>.</p> <p><em>Thank you for using nginx.</em></p> </body> </html> [root@centos-03 ~]#
7.浏览器访问失败缘由是服务器开启了iptables规则,关掉防火墙或者放行80端口vim
[root@centos-03 ~]# iptables -nvL
[root@centos-03 ~]# systemctl stop firewalld [root@centos-03 ~]# iptables -nvL Chain INPUT (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination [root@centos-03 ~]#
[root@centos-03 ~]# systemctl stop iptables
[root@centos-03 ~]# iptables -I INPUT -p tcp --dport 80 -j ACCEPT [root@centos-03 ~]#
8.查看nginx版本centos
[root@centos-03 ~]# nginx -V nginx version: nginx/1.14.0 built by gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) built with OpenSSL 1.0.2k-fips 26 Jan 2017 TLS SNI support enabled configure arguments: --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-

总结:首先配置一个nginx yum源,yum install安装,启动
http://nginx.org/en/download.html
1.下载源码包
[root@centos-03 ~]# cd /usr/local/src/ [root@centos-03 src]# wget http://nginx.org/download/nginx-1.14.0.tar.gz --2018-07-25 00:04:17-- http://nginx.org/download/nginx-1.14.0.tar.gz 正在解析主机 nginx.org (nginx.org)... 95.211.80.227, 206.251.255.63, 2001:1af8:4060:a004:21::e3, ... 正在链接 nginx.org (nginx.org)|95.211.80.227|:80... 已链接。 已发出 HTTP 请求,正在等待回应... 200 OK 长度:1016272 (992K) [application/octet-stream] 正在保存至: “nginx-1.14.0.tar.gz” 100%[======================================================================================>] 1,016,272 244KB/s 用时 4.1s 2018-07-25 00:04:22 (244 KB/s) - 已保存 “nginx-1.14.0.tar.gz” [1016272/1016272]) [root@centos-03 src]# ls filebeat-6.3.1-x86_64.rpm nginx-1.14.0.tar.gz [root@centos-03 src]#
[root@centos-03 src]# du -sh nginx-1.14.0.tar.gz 996K nginx-1.14.0.tar.gz [root@centos-03 src]#
2.解压tar包
[root@centos-03 src]# tar zxvf nginx-1.14.0.tar.gz
3.编译安装能够查看配置参数

4.src下面为nginx的核心源码文件
[root@centos-03 nginx-1.14.0]# cd src/ [root@centos-03 src]# ls core event http mail misc os stream [root@centos-03 src]#
[root@centos-03 src]# ls core/ nginx.c ngx_core.h ngx_hash.c ngx_module.h ngx_parse_time.h ngx_resolver.c ngx_string.c nginx.h ngx_cpuinfo.c ngx_hash.h ngx_murmurhash.c ngx_proxy_protocol.c ngx_resolver.h ngx_string.h ngx_array.c ngx_crc32.c ngx_inet.c ngx_murmurhash.h ngx_proxy_protocol.h ngx_rwlock.c ngx_syslog.c ngx_array.h ngx_crc32.h ngx_inet.h ngx_open_file_cache.c ngx_queue.c ngx_rwlock.h ngx_syslog.h ngx_buf.c ngx_crc.h ngx_list.c ngx_open_file_cache.h ngx_queue.h ngx_sha1.c ngx_thread_pool.c ngx_buf.h ngx_crypt.c ngx_list.h ngx_output_chain.c ngx_radix_tree.c ngx_sha1.h ngx_thread_pool.h ngx_conf_file.c ngx_crypt.h ngx_log.c ngx_palloc.c ngx_radix_tree.h ngx_shmtx.c ngx_times.c ngx_conf_file.h ngx_cycle.c ngx_log.h ngx_palloc.h ngx_rbtree.c ngx_shmtx.h ngx_times.h ngx_config.h ngx_cycle.h ngx_md5.c ngx_parse.c ngx_rbtree.h ngx_slab.c ngx_connection.c ngx_file.c ngx_md5.h ngx_parse.h ngx_regex.c ngx_slab.h ngx_connection.h ngx_file.h ngx_module.c ngx_parse_time.c ngx_regex.h ngx_spinlock.c [root@centos-03 src]#
5.编译安装,咱们只须要指定安装目录就能够了,到用到什么模块时咱们再编译安装对应的模块就能够了
[root@centos-03 nginx-1.14.0]# ./configure --prefix=/usr/local/nginx
[root@centos-03 nginx-1.14.0]# yum install -y gcc
[root@centos-03 nginx-1.14.0]# yum install -y pcre-devel
[root@centos-03 nginx-1.14.0]# yum -y install zlib-devel
6.make
[root@centos-03 nginx-1.14.0]# make
7.make install
[root@centos-03 nginx-1.14.0]# make install
[root@centos-03 nginx-1.14.0]# ls /usr/local/nginx/ conf html logs sbin [root@centos-03 nginx-1.14.0]#
8.查看版本
[root@centos-03 nginx-1.14.0]# /usr/local/nginx/sbin/nginx -V nginx version: nginx/1.14.0 built by gcc 4.8.5 20150623 (Red Hat 4.8.5-28) (GCC) configure arguments: --prefix=/usr/local/nginx [root@centos-03 nginx-1.14.0]#
9.启动的时候咱们须要将yum安装的nginx停掉
[root@centos-03 nginx-1.14.0]# /usr/local/nginx/sbin/nginx nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) ^C [root@centos-03 nginx-1.14.0]# systemctl stop nginx [root@centos-03 nginx-1.14.0]# /usr/local/nginx/sbin/nginx [root@centos-03 nginx-1.14.0]# ps aux|grep nginx root 9203 0.0 0.0 20548 612 ? Ss 00:32 0:00 nginx: master process /usr/local/nginx/sbin/nginx nobody 9204 0.0 0.1 20992 1076 ? S 00:32 0:00 nginx: worker process root 9206 0.0 0.0 112724 976 pts/0 R+ 00:33 0:00 grep --color=auto nginx [root@centos-03 nginx-1.14.0]#
10.查看下端口
[root@centos-03 nginx-1.14.0]# !net netstat -lntp 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 9203/nginx: master tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1419/sshd tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 2521/master tcp6 0 0 :::22 :::* LISTEN 1419/sshd tcp6 0 0 ::1:25 :::* LISTEN 2521/master [root@centos-03 nginx-1.14.0]#
11.访问下
[root@centos-03 nginx-1.14.0]# !curl curl 192.168.242.133 <!DOCTYPE html> <html> <head> <title>Welcome to nginx!</title> <style> body { width: 35em; margin: 0 auto; font-family: Tahoma, Verdana, Arial, sans-serif; } </style> </head> <body> <h1>Welcome to nginx!</h1> <p>If you see this page, the nginx web server is successfully installed and working. Further configuration is required.</p> <p>For online documentation and support please refer to <a href="http://nginx.org/">nginx.org</a>.<br/> Commercial support is available at <a href="http://nginx.com/">nginx.com</a>.</p> <p><em>Thank you for using nginx.</em></p> </body> </html> [root@centos-03 nginx-1.14.0]#
12.结束进程能够用killall nginx(或pkill),若是没有killall命令用rpm命令查找须要安装的包
[root@centos-03 nginx-1.14.0]# rpm -qf `which killall`
[root@centos-03 nginx-1.14.0]# yum install -y psmisc
[root@centos-03 nginx-1.14.0]# /usr/local/nginx/sbin/nginx [root@centos-03 nginx-1.14.0]# /usr/local/nginx/sbin/nginx -t nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful [root@centos-03 nginx-1.14.0]# /usr/local/nginx/sbin/nginx -s reload [root@centos-03 nginx-1.14.0]#
13.nginx服务管理脚本
https://coding.net/u/aminglinux/p/aminglinux-book/git/blob/master/D15Z/etc_init.d_nginx
[root@centos-03 nginx-1.14.0]# vim /etc/init.d/nginx^C [root@centos-03 nginx-1.14.0]# cat /etc/init.d/nginx #!/bin/bash # chkconfig: - 30 21 # description: http service. # Source Function Library . /etc/init.d/functions # Nginx Settings NGINX_SBIN="/usr/local/nginx/sbin/nginx" NGINX_CONF="/usr/local/nginx/conf/nginx.conf" NGINX_PID="/usr/local/nginx/logs/nginx.pid" RETVAL=0 prog="Nginx" start() { echo -n $"Starting $prog: " mkdir -p /dev/shm/nginx_temp daemon $NGINX_SBIN -c $NGINX_CONF RETVAL=$? echo return $RETVAL } stop() { echo -n $"Stopping $prog: " killproc -p $NGINX_PID $NGINX_SBIN -TERM rm -rf /dev/shm/nginx_temp RETVAL=$? echo return $RETVAL } reload() { echo -n $"Reloading $prog: " killproc -p $NGINX_PID $NGINX_SBIN -HUP RETVAL=$? echo return $RETVAL } restart() { stop start } configtest() { $NGINX_SBIN -c $NGINX_CONF -t return 0 } case "$1" in start) start ;; stop) stop ;; reload) reload ;; restart) restart ;; configtest) configtest ;; *) echo $"Usage: $0 {start|stop|reload|restart|configtest}" RETVAL=1 esac exit $RETVAL [root@centos-03 nginx-1.14.0]#
14.咱们先关掉nginx,而后用脚本启动,发现有冲突启动的是yum安装的那个nginx,咱们先把yum安装的卸载掉
[root@centos-03 nginx-1.14.0]# killall nginx
nginx: no process found
[root@centos-03 nginx-1.14.0]# chmod 755 /etc/init.d/nginx
[root@centos-03 nginx-1.14.0]# /etc/init.d/nginx start
Starting nginx (via systemctl): [ 肯定 ]
[root@centos-03 nginx-1.14.0]# !ps
ps aux|grep nginx

[root@centos-03 nginx-1.14.0]#
[root@centos-03 nginx-1.14.0]# yum remove -y nginx
15.再次成功启动了咱们编译安装的nginx
[root@centos-03 nginx-1.14.0]# ps aux|grep nginx
root 9320 0.0 0.0 112724 976 pts/0 S+ 01:10 0:00 grep --color=auto nginx
[root@centos-03 nginx-1.14.0]# /etc/init.d/nginx start
Starting nginx (via systemctl): [ 肯定 ]

#user nobody; (以哪一个用户运行worker进程,定义运行nginx服务的用户,还能够加上组,如 user nobody nobody;)
worker_processes 1; (定义worker进程有几个,这个数对应cpu个数,定义nginx子进程数量,即提供服务的进程数量,该数值建议和服务cpu核数保持一致。 除了能够定义数字外,还能够定义为auto,表示让系统自动调整。)
#error_log logs/error.log; (定义错误日志的路径,能够是相对路径(相对prefix路径的),也能够是绝对路径。 该配置能够在此处定义,也能够定义到http、server、location里)
#error_log logs/error.log notice;(定义错误日志路径以及日志级别. 错误日志级别:常见的错误日志级别有[debug|info|notice|warn|error|crit|alert|emerg],级别越高记录的信息越少。 若是不定义默认是error)
#error_log logs/error.log info;
#pid logs/nginx.pid; (定义nginx进程pid文件所在路径,能够是相对路径,也能够是绝对路径。)
events {
worker_connections 1024; (定义每一个work_process同时开启的最大链接数,即容许最多只能有这么多链接)
}
http {
include mime.types; (include mime.types; //cat conf/mime.types 定义nginx能识别的网络资源媒体类型(如,文本、html、js、css、流媒体等) default_type application/octet-stream; 定义默认的type,
若是不定义改行,默认为text/plain.)

"$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; 其中main为日志格式的名字,后面的为nginx的内部变量组成的一串字符串。)
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#access_log logs/access.log main; (定义日志的路径以及采用的日志格式,该参数能够在server配置块中定义。)
sendfile on; (是否调用sendfile函数传输文件,默认为off,使用sendfile函数传输,能够减小user mode和kernel mode的切换,从而提高服务器性能。 对于普通应用设为 on,若是用来进行下载等应用磁盘IO重负载应用,
可设置为off,以平衡磁盘与网络I/O处理速度,下降系统的负载。)
#tcp_nopush on; (当tcp_nopush设置为on时,会调用tcp_cork方法进行数据传输。 使用该方法会产生这样的效果:当应用程序产生数据时,内核不会立马封装包,而是当数据量积累到必定量时才会封装,而后传输。这样有助于解决网络
堵塞问题。 默认值为on。举例:快递员收快递、发快递,包裹累积到必定量才会发,节省运输成本。)
#keepalive_timeout 0;
keepalive_timeout 65; (该参数有两个值,第一个值设置nginx服务器与客户端会话结束后仍旧保持链接的最长时间,单位是秒,默认为75s。 第二个值能够省略,它是针对客户端的浏览器来设置的,能够经过curl -I看到header信息中有一项
Keep-Alive: timeout=60,若是不设置就没有这一项。 第二个数值设置后,浏览器就会根据这个数值决定什么时候主动关闭链接,Nginx服务器就不操心了。但有的浏览器并不承认该参数。)
#gzip on; (是否开启gzip压缩。)
server {
listen 80; (//监听端口为80,能够自定义其余端口,也能够加上IP地址,如,listen 127.0.0.1:8080;)

}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
