• CentOS7.3编译安装Nginx设置开机启动


    起因

    最近想玩nginx了,本来用yum -y install nginx安装也启动好了,但是买了本《Nginx高性能Web服务器详解》,我咋能辜负我的书费呢?于是我就直接ps -ef |grep nginx kill -QUIT master的pid,然后yum -y remove nginx了。没错,就是这么帅。

    经过

    下载nginx

    当然是去nginx(http://nginx.org/en/download.html)主页了,没错我现在安装的就是稳定版1.14.2了。
    进入放置nginx的目录,我是/usr/local/tools/nginx
    输入命令: wget http://nginx.org/download/nginx-1.14.2.tar.gz,这儿就等着吧。

    解压

    接下来解压targz包,你要是喜欢看动画呢,就输入 tar -zxvf nginx-1.14.2.tar.gz ,你要是不看呢就输入tar xf nginx-1.14.2.tar.gz

    安装nginx

    安装必要的工具:yum -y install gcc gcc-c++ automake pcre pcre-devel zlib zlib-devel open openssl-devel gd-devel perl-devel perl-ExtUtils-Embed .
    接下来未来保证源文件和二进制文件不重复,我进行了一波骚操作: mv nginx-1.14.2 nginx-1.14.2-installer mkdir nginx-1.14.2就是把源码文件夹重命名,新建了一个nginx按照目录,现在的源码在/usr/local/tools/nginx ginx-1.14.2-installer,我要安装在/usr/local/tools/nginx/nginx-1.14.2目录里。
    进入源码文件: cd nginx-1.14.2-installer,
    编译文件:./configure --prefix=/usr/local/tools/nginx/nginx-1.14.2,注意这儿改成你的目录就行了,有两点你的注意。其一、你的nginx.lock位置是在/var/lock/nginx.lock;其二、只安装了标准模块;其三、用户不限制,任何人都能启动nginx
    我的完整的配置选项是这样子的(如果你也是用的修改的配置,一定要把这个配置信息记下来,否则以后查错,该配置你会哭的。):/configure --prefix=安装目录 --sbin-path=sbin/nginx --conf-path=conf/nginx.conf --pid-path=logs/nginx.pid --error-log-path=logs/error.log --http-log-path=logs/access.log --lock-path=logs/lock/subsys/nginx --user=你要启动nginx的用户 --with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_gzip_static_module --with-http_stub_status_module --with-http_perl_module --with-ld-opt="-Wl,-E" --with-http_image_filter_module--prefix是安装目录,一定要使用绝对路径;我把lock文件也放在了安装目录下的logs下;启用了几个基本模块
    一定要注意这时候是不是报错了。
    然后就是 make && make install

    测试安装成功

    进入安装目录:cd ../nginx-1.14.2,
    执行启动: ./sbin/nginx,如果启动报错的话,看下错误信息,一般情况下是啥也没有。
    查看服务: ps -ef |grep nginx

    停止服务:kill -QUIT 7555,这个7555对应的是上图master process的进程编号,为了后续启动这儿一定要停了服务
    查看服务: ps -ef |grep nginx

    配置系统服务

    配置系统服务:vim /etc/init.d/nginx
    将下面这段复制进去(这是官网提供的加入系统服务脚本,链接 Red Hat NGINX Init Script ,找到nginx="/usr/local/tools/nginx/nginx-1.14.2/sbin/nginx" NGINX_CONF_FILE="/usr/local/tools/nginx/nginx-1.14.2/conf/nginx.conf"这两句改成你自己的目录):

       if [ -n "$user" ]; then
          if [ -z "`grep $user /etc/passwd`" ]; then

          fi
          options=`$nginx -V 2>&1 | grep 'configure arguments:'`
          for opt in $options; do

                  value=`echo $opt | cut -d "=" -f 2`
                  if [ ! -d "$value" ]; then
                      # echo "creating" $value
                      mkdir -p $value && chown -R $user $value
                  fi
              fi
           done
        fi

    start() {

        make_dirs
        echo -n $"Starting $prog: "

        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
    

    配置启动脚本权限:chmod a+x /etc/init.d/nginx
    启动nginx: /etc/init.d/nginx start
    停止nginx: /etc/init.d/nginx stop

    加入系统服务:chkconfig --add /etc/init.d/nginx
    使用systemctl启动nginx: systemctl start nginx
    使用systemctl停止nginx: systemctl stop nginx

    开机启动

    配置开机启动:vi /etc/rc.local在最后加一句/etc/init.d/nginx start

    结尾

    打完收功!
