Linux 编译安装 nginx

很久没有登我的博客园了，这两年一直埋头写代码，最近突然觉得，需要为自己技术积累的过程留下一个记录，等哪一天可以回来看看曾经菜鸟的自己。

废话不多说，这次编译安装nginx是在阿里云 Centos7 环境下进行的，安装的 nginx 版本为：1.19.1 ，每一步安装过程除了命令之外，我会尽可能将操作过程进行截图展示，保证信息展示的完整性。

1. 进行源码下载准备：

wget http://nginx.org/download/nginx-1.19.1.tar.gz

2. 对源码进行解压：

tar -zxf nginx-1.19.1.tar.gz

cd nginx-1.19.1

3. 安装相关的编译环境

yum update
yum -y install gcc pcre pcre-devel zlib zlib-devel openssl openssl-devel

4. 编译安装

#添加用户和组
groupadd www
useradd -g www www

#配置
./configure \
--user=www \
--group=www \
--prefix=/usr/local/nginx \
--with-http_ssl_module \
--with-http_stub_status_module \
--with-http_realip_module \
--with-threads

#编译
make

#安装
make install

5. 安装完成之后进行验证

/usr/local/nginx/sbin/nginx -V

如此，安装nginx完成。

下面进行相关的配置：

6. 创建软链接

ln -s /usr/local/nginx/sbin/nginx /usr/bin/nginx

7. 设置开机自启动

vim /etc/init.d/nginx

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15
# description:  NGINX is an HTTP(S) server, HTTP(S) reverse \
#               proxy and IMAP/POP3 proxy server
# processname: nginx
# config:      /usr/local/nginx/conf/nginx.conf
# config:      /etc/sysconfig/nginx
# pidfile:     /usr/local/nginx/logs/nginx.pid
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0
nginx="/usr/local/nginx/sbin/nginx"
prog=$(basename $nginx)
NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf"
[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
lockfile=/var/lock/subsys/nginx
make_dirs() {
   # make required directories
   user=`$nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`
   if [ -z "`grep $user /etc/passwd`" ]; then
       useradd -M -s /bin/nologin $user
   fi
   options=`$nginx -V 2>&1 | grep 'configure arguments:'`
   for opt in $options; do
       if [ `echo $opt | grep '.*-temp-path'` ]; then
           value=`echo $opt | cut -d "=" -f 2`
           if [ ! -d "$value" ]; then
               # echo "creating" $value
               mkdir -p $value && chown -R $user $value
           fi
       fi
   done
}
start() {
    [ -x $nginx ] || exit 5
    [ -f $NGINX_CONF_FILE ] || exit 6
    make_dirs
    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
    sleep 1
    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 2
esac

赋予脚本可执行权限：

chmod a+x /etc/init.d/nginx

将 nginx 服务加入 chkconfig 管理列表

chkconfig --add /etc/init.d/nginx
chkconfig nginx on
# 启动
systemctl start nginx

8. 测试一下

curl localhost:80

输出：

 1 <!DOCTYPE html>
 2 <html>
 3 <head>
 4 <title>Welcome to nginx!</title>
 5 <style>
 6     body {
 7         width: 35em;
 8         margin: 0 auto;
 9         font-family: Tahoma, Verdana, Arial, sans-serif;
10     }
11 </style>
12 </head>
13 <body>
14 <h1>Welcome to nginx!</h1>
15 <p>If you see this page, the nginx web server is successfully installed and
16 working. Further configuration is required.</p>

22 
23 <p><em>Thank you for using nginx.</em></p>
24 </body>
25 </html>

9. 配置优化

下列配置在 nginx.conf 里与 http 节点同级

cd /usr/local/nginx/conf
vim nginx.conf

user  www www;
worker_processes auto;
worker_rlimit_nofile 51200;

events
    {
        use epoll;
        worker_connections 51200;
        multi_accept on;
    }

http 节点下加入下列配置，将会从指定目录加载配置文件

include /etc/nginx/*.conf;

10. 常用命令

# 启动
systemctl start nginx
# 查看状态
systemctl status nginx
# 停止
systemctl stop nginx

# 重载配置
nginx -s reload
# 测试配置是否正确
nginx -t
