# 前言 #

# 一：升级lib库 #

### 1.1：参考文档 ###

### 1.2：升级原因 ###

*  启动服务后，发现调用有问题，通过观察日志发现是lib库的问题，使用命令查看lib库
 *      [root@test lib]# ls
        libdbc.so  libdbc.so.bak111
        [root@test lib]# ldd libdbc.so
        ldd: warning: you do not have execution permission for `./libdbc.so'
        ./libdbc.so: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by ./libdbc.so)
        ./libdbc.so: /lib64/libstdc++.so.6: version `CXXABI_1.3.8' not found (required by ./libdbc.so)
        ./libdbc.so: /lib64/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by ./libdbc.so)
        ./libdbc.so: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by ./libdbc.so)
        	linux-vdso.so.1 =>  (0x00007ffc11be9000)
        	libstdc++.so.6 => /lib64/libstdc++.so.6 (0x00007fbaf52ae000)
        	libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007fbaf5098000)
        	libc.so.6 => /lib64/libc.so.6 (0x00007fbaf4ccb000)
        	libm.so.6 => /lib64/libm.so.6 (0x00007fbaf49c9000)
        	/lib64/ld-linux-x86-64.so.2 (0x00007fbaf55b6000)
 *  发现报错，缺少GLIBCXX\_3.4.20版本的内容，使用命令查看是否缺少
 *      [root@test ~]# strings /usr/lib64/libstdc++.so.6 | grep GLIBCXX
        GLIBCXX_3.4
        GLIBCXX_3.4.1
        GLIBCXX_3.4.2
        GLIBCXX_3.4.3
        GLIBCXX_3.4.4
        GLIBCXX_3.4.5
        GLIBCXX_3.4.6
        GLIBCXX_3.4.7
        GLIBCXX_3.4.8
        GLIBCXX_3.4.9
        GLIBCXX_3.4.10
        GLIBCXX_3.4.11
        GLIBCXX_3.4.12
        GLIBCXX_3.4.13
        GLIBCXX_3.4.14
        GLIBCXX_3.4.15
        GLIBCXX_3.4.16
        GLIBCXX_3.4.17
        GLIBCXX_3.4.18
        GLIBCXX_3.4.19
        GLIBCXX_DEBUG_MESSAGE_LENGTH
        [root@test ~]# ll  /usr/lib64/libstdc++.so.6	'//发现当前是链接到19版本的'
        lrwxrwxrwx. 1 root root 19 Jun 25  2018 /usr/lib64/libstdc++.so.6 -> libstdc++.so.6.0.19
 *  确实没有，需要升级解决

### 1.3：升级解决 ###

*  下载新版本库并解压
 *      wget https://adbin.top/packages/lib64.tar.gz
        [root@test ~]# mkdir /usr/lib64_version_25
        [root@test ~]# tar zxf lib64.tar.gz -C /usr/lib64_version_25/
 *  移动并重新连接
 *      cp /usr/lib64_version_25/lib64/libstdc++.so.6.0.25 /usr/lib64/
        ll  /usr/lib64/libstdc++.so.*
        
        [root@test ~]# ll  /usr/lib64/libstdc++.so.*
        lrwxrwxrwx  1 root root       30 Apr  1 11:42 /usr/lib64/libstdc++.so.6 -> /usr/lib64/libstdc++.so.6
        .0.19
        -rwxr-xr-x. 1 root root   995840 Apr 10  2018 /usr/lib64/libstdc++.so.6.0.19
        -rwxr-xr-x  1 root root 12129824 Apr  1 11:42 /usr/lib64/libstdc++.so.6.0.25
        [root@test ~]# 
        [root@test ~]# ln -sf /usr/lib64/libstdc++.so.6.0.25 /usr/lib64/libstdc++.so.6
        [root@test ~]# ll  /usr/lib64/libstdc++.so.*
        lrwxrwxrwx  1 root root       30 Apr  1 11:42 /usr/lib64/libstdc++.so.6 -> /usr/lib64/libstdc++.so.6
        .0.25
        -rwxr-xr-x. 1 root root   995840 Apr 10  2018 /usr/lib64/libstdc++.so.6.0.19
        -rwxr-xr-x  1 root root 12129824 Apr  1 11:42 /usr/lib64/libstdc++.so.6.0.25
 *  重新查看
 *      strings /usr/lib64/libstdc++.so.6 | grep GLIBCXX
        [root@test lib]# ldd libdbc.so
        ldd: warning: you do not have execution permission for `./libdbc.so'
        	linux-vdso.so.1 =>  (0x00007ffd6b731000)

        [root@test lib]# ldconfig
