【操作记录】CentOS编译安装nginx

下载

wget http://nginx.org/download/nginx-1.9.6.tar.gz

解压缩

tar zxvf nginx-1.9.6.tar.gz

进入nginx目录

cd nginx-1.9.6

设置，编译，安装（configure过程可能出现的情况，见文章最尾）

./configure --prefix=/home/server/nginxmake && make install && make clean

添加用户组www

groupadd www

向用户组www添加用户www

useradd -r -g www -s /bin/false www

修改nginx配置文件

vi /home/server/nginx/conf/nginx.conf

user www;#CPU Core options#Nginx每个进程耗费10M~12M内存，这里只开启一个Nginx进程，节省内存。worker_processes  1;# 日志类型 [ debug | info | notice | warn | error | crit ]#error_log  logs/error.log;#error_log  logs/error.log  notice;#error_log  logs/error.log  info;error_log  logs/nginx_error.log error;#nginx Process options#pid        logs/nginx.pid;#Specifies the value for maximum file descriptors that can be opened by this process.worker_rlimit_nofile 51200;events {    use epoll;    #maxclient = worker_processes * worker_connections / cpu_number    worker_connections 51200;}http {    include       mime.types;    default_type  application/octet-stream;    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '    #                  '$status $body_bytes_sent "$http_referer" '    #                  '"$http_user_agent" "$http_x_forwarded_for"';    #access_log  logs/access.log  main;    # 设置默认文档格式    charset utf8;    # General options    server_names_hash_bucket_size 128;    client_header_buffer_size 32k;    large_client_header_buffers 4 32k;    # ignore_invalid_headers on;    # recursive_error_pages on;    server_name_in_redirect off;    sendfile on;    # timeouts    keepalive_timeout 60;    # TCP options    tcp_nopush on;    tcp_nodelay on;    #fastcgi options    fastcgi_connect_timeout 300;    fastcgi_send_timeout 300;    fastcgi_read_timeout 300;    fastcgi_buffer_size 64k;    fastcgi_buffers 4 64k;    fastcgi_busy_buffers_size 128k;    fastcgi_temp_file_write_size 128k;    # fastcgi_intercept_errors on;    # size limits    client_max_body_size 100m;    # client_body_buffer_size 256k;    # gzip  compression    # 对网页文件、CSS、JS、XML等启动gzip压缩，减少数据传输量，提高访问速度。    gzip on;    gzip_min_length 1k;    gzip_buffers 4 16k;    gzip_http_version 1.0;    gzip_comp_level 2;    gzip_types text/plain text/css application/x-javascript application/xml;    gzip_vary on;    # limit_zone  crawler  $binary_remote_addr  10m;    # 包含所有虚拟主机的配置文件    include vhosts/*.conf;}

创建针对localhost的配置文件

vi /home/server/nginx/conf/vhosts/localhost.conf

内容如下

server {    listen       80;    server_name  localhost;    location / {        # 网站根目录        root   /home/webroot/localhost;        # 默认文档        index  index.html index.htm;    }    # redirect server error pages to the static page /50x.html    #    error_page   500 502 503 504  /50x.html;    location = /50x.html {        root   html;    }}

创建nginx系统服务脚本

vi /etc/init.d/nginx

填入如下内容

#!/bin/sh##nginx - this script starts and stops the nginx daemin## chkconfig:   - 85 15# description:  Nginx is an HTTP(S) server, HTTP(S) reverse \#               proxy and IMAP/POP3 proxy server# processname: nginx# config:      /home/server/nginx/conf/nginx.conf# pidfile:     /data/webroot/logs/localhost/nginx.pid# Source function library.. /etc/rc.d/init.d/functions# Source networking configuration.. /etc/sysconfig/network# Check that networking is up.[ "$NETWORKING" = "no" ] && exit 0nginx="/home/server/nginx/sbin/nginx" # nginx启动文件prog=$(basename $nginx)NGINX_CONF_FILE="/home/server/nginx/conf/nginx.conf" # 配置文件路径lockfile=/var/lock/subsys/nginxstart() {    [ -x $nginx ] || exit 5    [ -f $NGINX_CONF_FILE ] || exit 6    echo -n $"Starting $prog: "    daemon $nginx -c $NGINX_CONF_FILE    retval=$?    echo    [ $retval -eq 0 ] && touch $lockfile    return $retval}stop() {    echo -n $"Stopping $prog: "    killproc $prog -QUIT    retval=$?    echo    [ $retval -eq 0 ] && rm -f $lockfile    return $retval}restart() {    configtest || return $?    stop    start}reload() {    configtest || return $?    echo -n $"Reloading $prog: "    killproc $nginx -HUP    RETVAL=$?    echo}force_reload() {    restart}configtest() {  $nginx -t -c $NGINX_CONF_FILE}rh_status() {    status $prog}rh_status_q() {    rh_status >/dev/null 2>&1}case "$1" in    start)        rh_status_q && exit 0        $1        ;;    stop)        rh_status_q || exit 0        $1        ;;    restart|configtest)        $1        ;;    reload)        rh_status_q || exit 7        $1        ;;    force-reload)        force_reload        ;;    status)        rh_status        ;;    condrestart|try-restart)        rh_status_q || exit 0            ;;    *)        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"        exit 2esac

保存

:wq

对脚本添加可执行权限

chmod +x /etc/init.d/nginx

启动nginx

/etc/init.d/nginx start

添加nginx到自启动服务

chkconfig --add nginx

设置开机启动

chkconfig nginx on

开启访问端口

vi /etc/sysconfig/iptables

添加如下

-A INPUT –m state –state NEW –m tcp –p tcp –dport 80 –j ACCEPT

重启防火墙以应用规则

/etc/init.d/iptables restart

此后，执行命令脚本即可，无需执行原路径的执行文件

/etc/init.d/nginx start     # 启动nginx/etc/init.d/nginx stop      # 停止nginx/etc/init.d/nginx restart   # 重启nginx/etc/init.d/nginx reload    # 重新加载配置文件

原操作命令

/data/server/nginx/sbin/nginx               # start server/data/server/nginx/sbin/nginx -s stop       # fast shutdown/data/server/nginx/sbin/nginx -s quit       # graceful shutdown/data/server/nginx/sbin/nginx -s reload     # reloading the configuration file/data/server/nginx/sbin/nginx -s reopen     # reopening the log files

至此，nginx的安装与最基本的配置已完成

configure过程可能出现的情况

缺少C编译器，需要安装gcc
运行安装命令，yum install -y gcc

未安装PCRE
运行安装命令，yum install -y pcre pcre-devel

运行安装命令，yum install -y openssl openssl-devel
