08 Tengine安装,


目标

1. 合并js、css文件
2. 后端服务器健康检查     http://{ip_addr}/status,查看后端服务器的状态

QA

1.安装PCRE库里,会提示找不到c++编译库

安装c++
yum install -y gcc gcc-c++

2. 安装nginx完成后,运行时会报错

[error while loading shared libraries: libpcre.so.1](https://www.oschina.net/question/12_78952)
定位错误原因:
[root@localhost nginx-1.8.0]#  ldd $(which /usr/local/nginx/sbin/nginx)
    linux-vdso.so.1 =>  (0x00007fffe61ff000)
    libpthread.so.0 => /lib64/libpthread.so.0 (0x0000003c29c00000)
    libcrypt.so.1 => /lib64/libcrypt.so.1 (0x0000003c35400000)
    libpcre.so.1 => not found
    libz.so.1 => /lib64/libz.so.1 (0x0000003c2ac00000)
    libc.so.6 => /lib64/libc.so.6 (0x0000003c29800000)
    /lib64/ld-linux-x86-64.so.2 (0x0000003c29000000)
    libfreebl3.so => /lib64/libfreebl3.so (0x0000003c34800000)
    libdl.so.2 => /lib64/libdl.so.2 (0x0000003c29400000)

解决办法:   
[root@localhost lib64]# cd /lib64
[root@localhost lib64]# ln -s libpcre.so.0.0.1 libpcre.so.1

3. 安装报没有Perl 5

yum install perl

4. 启用concat模块(使用shard模式编译,需要手动开启concat模块)

dso {
    load ngx_http_concat_module.so;
}

安装

在Centos下,yum源不提供nginx的安装,可以通过切换yum源的方法获取安装。也可以通过直接下载安装包的方法,以下命令均需root权限执行

首先安装必要的库(nginx 中gzip模块需要 zlib 库,rewrite模块需要 pcre 库,ssl 功能需要openssl库)。选定/usr/local为安装目录,以下具体版本号根据实际改变。

1.安装PCRE库

$ cd /usr/local/
$ wget http://nchc.dl.sourceforge.net/project/pcre/pcre/8.36/pcre-8.36.tar.gz
$ tar -zxvf pcre-8.36.tar.gz
$ cd pcre-8.36
$ ./configure
$ make
$ make install

2.安装zlib库

$ cd /usr/local/ 
$ wget http://zlib.net/zlib-1.2.11.tar.gz
$ tar -zxvf zlib-1.2.11.tar.gz
$ cd zlib-1.2.11
$ ./configure
$ make
$ make install

3.安装ssl

$ cd /usr/local/
$ wget http://www.openssl.org/source/openssl-1.0.1j.tar.gz
$ tar -zxvf openssl-1.0.1j.tar.gz
$ cd openssl-1.0.1j
$ ./config
$ make
$ make install

4.安装Tengine

$ cd /usr/local/
$ wget http://tengine.taobao.org/download/tengine-2.2.0.tar.gz
$ tar -zxvf tengine-2.2.0.tar.gz
$ cd tengine-2.2.0 
$ ./configure --prefix=/usr/local/nginx --with-http_concat_module --with-http_upstream_check_module --with-http_stub_status_module --with-openssl=/usr/local/openssl-1.0.1j --with-pcre=/usr/local/pcre-8.36
$ make
$ make install

5.启动

$ /usr/local/nginx/sbin/nginx

检查是否启动成功:

打开浏览器访问此机器的 IP,如果浏览器出现 Welcome to nginx! 则表示 Nginx 已经安装并运行成功。

6. 使用非root用户启动nginx

su root
chown root:${cws} nginx       启动nginx的用户
chmod +s nginx                        增加权限

部分命令如下:

重启:
$ /usr/local/nginx/sbin/nginx -s reload

停止:
$ /usr/local/nginx/sbin/nginx -s stop

测试配置文件是否正常:
$ /usr/local/nginx/sbin/nginx -t

强制关闭:
$ pkill nginx

使用示例

==== html部分 ====
<script src="/public/js/??jquery.min.js,index.js,blog/b1.js,blog/b2.js"></script>

==== nginx配置部分(合并css、js) ====
location /public/js/ {
    concat on;
}
location / {
    root   html;
    index  index.html index.htm;
}

使用完整示例(后端健康检查)

#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

    gzip  on;

    upstream cluster1 {

        access_log  logs/host.access.log  main;

        location / {

        }
        
        location /status {
            check_status;
            #access_log   off;
            #allow SOME.IP.ADD.RESS;
            #deny all;
        }
        
        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }

}
