9.1.4. nginx

9.1.4.1. 安装

9.1.4.1.1. 官网下载好压缩包，并解压

9.1.4.1.2. 安装依赖

yum -y install gcc automake autoconf libtool make

9.1.4.1.3. 执行 ./configure 命令进行初始化

进入安装目录运行 ./configure 进行初始化

./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.

如果出现错误：首先尝试nginx目录下的自带依赖包

# 查找pcre的路径。找到之后追加到初始化命令后面
$ find / -name pcre  

# 先尝试下面的命令是否能成功，如果不能成再追加 --with-zlib=/mnt/sit/app/nginx-1.13.2/auto/lib/zlib
$ ./configure --with-pcre=/mnt/sit/app/nginx-1.13.2/auto/lib/pcre --with-zlib=/mnt/sit/app/nginx-1.13.2/auto/lib/zlib --with-openssl=/mnt/sit/app/nginx-1.13.2/auto/lib/openssl

如果安装成功则会显示如下信息

...

  + OpenSSL library is not used
  + using system zlib library

  nginx http fastcgi temporary files: "fastcgi_temp"
  nginx http uwsgi temporary files: "uwsgi_temp"
  nginx http scgi temporary files: "scgi_temp"

如果安装失败。请手动安装倚赖包

1. 安装pcre
    1. 检查CentOS系统是否安装prce，，如果已安装则会显示pcre的版本信息
        [root@localhost /]# rpm -qa pcre
        pcre-7.8-6.el6.i686
    2.删除pcre包
        [root@localhost /]# rpm -e --nodeps pcre
        [root@localhost /]# rpm -qa pcre
    3.在线安装pcre
        [root@localhost /]# yum install pcre
    4.查看pcre的安装路径
        [root@localhost /]# rpm -qa pcre
    pcre-7.8-6.el6.i686
        [root@localhost /]# rpm -ql pcre-7.8-6.el6.i686
2. 安装编译依赖库yum install gcc gcc-c++ openssl openssl-devel zib-devel zib

安装成功之后，执行命令

$ make install

9.1.4.2. 上面的安装依然失败了，直接按照官网的安装文档

http://www.nginx.cn/install

就是最后初始化的时候，除了openssl需要指定地址外。剩下的不用再指定了。会自动找到的装成功之后的目录是在初始化显示的 nginx path prefix: "/usr/local/nginx" 目录中

# 启动
sudo /usr/local/nginx/nginx
# 如果报错  /usr/local/nginx/nginx: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory

## 先查看
ldd $(which /usr/local/nginx/sbin/nginx)

[root@localhost lib]# ldd $(which /usr/local/nginx/sbin/nginx)

# 可以看到上面的确是未找到。
# 手动关联一下
cd /lib
ln -s /lib/libpcre.so.0.0.1 /lib/libpcre.so.1
# 会发现还是没有找到.有可能你的机器是x64的。执行以下代码
ln -s /usr/local/lib/libpcre.so.1 /lib64/

9.1.4.3. 启动命令等

首先进入nginx安装目录，下面的命令都是在该目录中执行的

cd /usr/local/nginx
# 如果执行不了nginx命令的话就进入sbin目录
cd /usr/local/nginx/sbin

测试配置文件是否有异常

./nginx -t
``
指定配置文件启动：
```bash
# 这里的conf文件使用的相对路径需要区分当前目录是sbin还是根目录
./nginx -c ./conf/nginx.conf

修改了配置文件，重启

./nginx -s reload

停止服务

./nginx -s stop
