linux編譯安裝及配置Nginx(包含pcre), 日誌定時切割__linux

 

@安裝pcre(Nginx的Urlrewrite模組依賴PCRE)
        # wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.12.tar.gz
        # tar zxvf pcre-8.12.tar.gz
        # cd pcre-8.12
        # ./configure --prefix=/usr/local/webserver/pcre
        # make && make install
        # cp /usr/local/webserver/pcre/lib/libpcre.a /usr/local/webserver/pcre/libpcre.a
        # cp /usr/local/webserver/pcre/lib/libpcre.la /usr/local/webserver/pcre/libpcre.la
        # cp /usr/local/webserver/pcre/include/pcre.h /usr/local/webserver/pcre/pcre.h
                複製到pcre目錄
        # mkdir /usr/local/webserver/pcre/.libs
                建立.libs檔案夾
        # cp /usr/local/webserver/pcre/lib/libpcre.a /usr/local/webserver/pcre/.libs/libpcre.a
        # cp /usr/local/webserver/pcre/lib/libpcre.la /usr/local/webserver/pcre/.libs/libpcre.la
        # cp /usr/local/webserver/pcre/include/pcre.h /usr/local/webserver/pcre/.libs/pcre.h
                複製到.lib檔案夾

@安裝nginx /usr/local/nginx
        # wget http://nginx.org/download/nginx-1.0.10.tar.gz
        # tar zxvf nginx-1.0.10.tar.gz
        # cd nginx-1.0.10
        # ./configure --user=nobody --group=nobody --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module
                配置時出錯, pcre為編譯安裝,要指定pcre路徑
                ./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= option.
        # ./configure --user=nobody --group=nobody --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/webserver/pcre
        # make && make install
                報錯: Nginx不能很好的識別到系統中的PCRE
                make -f objs/Makefile
                make[1]: Entering directory `/usr/local/nginx-1.0.10'
                cd /usr/local/webserver/pcre \
                        && if [ -f Makefile ]; then make distclean; fi \
                        && CC="gcc" CFLAGS="-O2 -fomit-frame-pointer -pipe " \
                        ./configure --disable-shared
                /bin/sh: line 2: ./configure: No such file or directory
                make[1]: *** [/usr/local/webserver/pcre/Makefile] Error 127
                make[1]: Leaving directory `/usr/local/nginx-1.0.10'
                make: *** [build] Error 2
        # ./configure --user=nobody --group=nobody --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/webserver/pcre
        # vi objs/Makefile
                尋找configure --disable-shared,在1089行,刪除./configure --disable-shared, 儲存
                :st nu可顯示行號
                :1089直接跳到1089行
        #make && make install


@建立Nginx日誌目錄
        mkdir -p /var/log/nginx
        chmod +w /var/log/nginx
        chown -R nobody:nobody /var/log/nginx

@建立Nginx設定檔
        #mv /usr/local/webserver/nginx/conf/nginx.conf  nginx.conf-
        #vi /usr/local/webserver/nginx/conf/nginx.conf

@啟動Nginx
        #ulimit -SHn 51200
                使用ulimit -a 可以查看當前系統的所有限制值，使用ulimit -n 可以查看當前的最大開啟檔案數。
                新裝的linux預設只有1024，當作負載較大的伺服器時，很容易遇到error: too many open files。因此，需要將其改大。
                使用 ulimit -n 65535 可即時修改，但重啟後就無效了。（注ulimit -SHn 65535 等效 ulimit -n 65535，-S指soft，-H指hard)
        #/usr/local/webserver/nginx/sbin/nginx     ----->啟動
